Fast Flowmeter application

Sometimes a process is thát critical and each deviation in flowrate must be noticed and compensated for.
A customer application involves water with potentially some short disturbances in flowrate.
With water as medium, lots of measurement methods can be used to measure flow, why chose Ultrasonic measurement then?
The reason is in the additionla requirements.

Requirements mark the playing ground

There’s always more than one requirement when a flowmeter is being considered. In this Fast Flowmeter process, speed was obviously key-requirement number one!
Next to a quick response, it would be beneficial that the flowmeter would disturb the water-flow the least possible.
In addition, and related to that, a minimal pressure-drop could be allowed, pressure plays an important role in this customer’s process.
A last requirement has to do with accuracy and scaling. The current maximum flowrate is 12 liters per minute. This may rise a bit in the future, so additional capacity is not bad, but 12 l/min should be in the accuracy-range of the instrument.

Weighted requirements

In itself the above requirements would qualify for four types of Flowmax ultrasonic flowmeters.
To come to a ranking, the requirements are weighted, the most critical requirement is counted five times, the least important only once.
By judging with weighted requirements, it became obvious that the Flowmax 44i has the best overall score.

From good to better

All four considered flowmeters are equally fast, have an open bore and no moving parts. On that behalf, they are all good.
What made the difference is the close-to-straight bore of Flowmax 44.
The straight bore of DN10 matches ideally with the piping inner diameter. This results in low pressure-drop and in less noise in the flow itself.
Great how a non-critical parameter can make a small diference at the end.

How fast is Flowmax-fast?

The application may have minor disturbances that may last no longer than 0.1 second. Or 100 milliseconds to make it sound more 😉
Flowmax sensorics deliver 250 internal measurement values every second, that’s one reading every 4 milliseconds (!)

A minimum damping level is hard-coded in the Flowmax calculator, averaging each 4 measurements and providing the outcome as an output to the world. That makes the fastest rate 4×4= 16 milliseconds.
Do you have 3.05 minutes? Watch this video of the importance of milliseconds for athletes.!

Reduced speed on demand

On demand, the user may want to increase damping of the signal.

With increased damping , the meter still takes 250 measurements per second.
The difference is that a lot of things happen inside the calculator, with an end-effect resulting in one output signal every 2 seconds for example.
This damping is an important factor in PID-control cycles.

Optional: PID in the meter itself

PID software is optionally available in the Flowmax instruments. Tell us your aplication and get fast advise.

(This may take more than 16 milliseconds)

 

 

Eire flowmeter – Ireland

Ireland has an impressive industry in bio-pharmaceutical companies.
The world-wide top ranking of medicine-makers, at least has a plant in Ireland.
Given the fact that bio-medical production often invloves liquids, the Irish industry has a need for instrumentation for liquid-monitoring and -dosing.

Not an ordinary instrument

Process-control solutions in regular industries form the basis of instruments which can -and are allowed to- be used in hazardous processes such as bio-pharmacy.
The proven technology has to be translated into a capable design, approved materials, methods and shapes.
Once functional, the instrument will undergo an intensive trajectory of validation and approval before it can be introduced commercially.

Flowmeister is proud to intoduce the Eire Flowmeter for ireland. It’s a high-end solution, with the requirements properly in place for a quick plug-validate-play scenario.
Developed in 2014-2015, the MIB Flowmax 242i, a Single Use ultrasonic flowmeter, is readily available.

 

Less is more

Ranging from 0.015 liter per minute up to 24 liter per minute with four different measuring-tubes we believe to offer solutions to cover the spectrum of regular applications in the bio-pharmaceutical industry.
Knowing that the cost of an ultrasonic instrument is somewhat more than simple meters, it’s good to bring some relativity in the scale.


A first factor is a matter of smart design.
Only the wetted parts are to be disposed, the valuable calculator and electronics remain for a lifetime.
Secondly, the accuracy is high, better tan 1% of measured value, even at fluctuating flowrates! Ultrasound is fast, we give you a measurement every 16 milliseconds (if you like).
Thirdly, the instrument has a free bore, with no obstacles no moving parts and only one wetted material.

Inquire for your Eire Flowmeter

A soon response is ensured!

Your instrument has been tested, which is certified with the delivery. Optionally, a 3- or 8-point calibration-certificate can be ordered to prove the exact accuracy.

Flowmeter chemical and chemics

flowmeter chemie

<Dutch version here >

Within chemical processes, a controlled and regulated flowrate is one of the key-parameters to ensure a safe and succesful process.
The top-three features in this sector are:
– Safety
– Reliability
– Repeatability
The ultrasonic flowmeter for chemicals robustly fills in these three demands. In addition, the instruments are fast and accurate, which is an advantage in processes with fluctuating flow, such as fast dosing processes.

Chemical Flowmeter is all about material-properties

Each aspect in a product-design is important, but for the chemical flowmeter the choice of materials is crucial.
Imagine one of the wetted parts being insufficiently resistant to your fluid, what would the consequences be….?
If safety cannot be guaranteed, who wants to know about reliability or repeatability?

The MIB flowmeter named Flowmax, is not a one-size-fits-all solution, it is a whole range of instruments with different shapes and materials.
Besides some specific properties, all instruments have five important features in common:


– Plastic housing
– Free bore
– No moving parts
– Smooth inner surface
-No electrodes or metals, just one wetted part!

Some examples of Flowmax

PSU polysulfon flowmeter chemie

 

 

The basis instrument is Flowmax 44i, made of PolySulfon (PSU)
This typical black shiny housing is injection-moulded, resulting in zero gaps or joints in the wetted area.
Usable for multiple properties of conducting or non-conducting liquids, but not for Chloride.

 

 

 

 

 

PVDF flowmeter chemie

 

A real pro in chemical flowmeasurement is Flowmax 400, made of PFA and also injection moulded.
Its usability excels in the lower flowranges, down to one liter per hour.
Integration  in tubing systems makes a perfect fit with the integrated flare-connections.
Adaptor to threaded process-connection is optionally available.

 

 

 

PE flowmeter chemie

 

Higher flowrates up to 900 liter per minute are possible with the Flowmax 54i range. The machined body gives additional flexibility in material and process-connection.
Standard material is PE-HD because of the good properties in lightly aggressive media. Process connection is outer thread.
Flowmax 54i is also available in the extremely resistant PE-Xc and in poly-propylene (PP).
Customized process-connections are possible on demand.

 

 

flowmeter chemie Flowmax 242i

 

Another variant is Flowmax 242i, also in a machined PE-HD body with possibilities and certification for application in bio-chemical and bio-pharmaceutical environments.

Not just any material, but the result of a fully validated and certified design-trajectory.

What’s particularly interesting is the re-use of the standard electronics housing (in black PSU) whilst the wetted measuring-tube is made of the mandatory certified PE_HD.

New material PE-Xc for PE Flowmeter

PE flowmeter chemie

Application-driven development leads to new products. This is an overview of high-end flowmeters in PE-Xc

Why develop Flowmax in PE?

Flowmax has been available in chemically resistant materials since years.
Why making the addition to existing Flowmax series in PSU and PFA?
MIB GmbH has developed the Flowmax in HDPE for two reasons:

Reason 1: Flexibility
Existing Flowmax 44 (in PSU) and 400 (in PFA) are based on die-casting. This is a good manufacturing-process, but is limited in flexibility because of the existing moulds.
The ability to machine every shape allows for a wide range in:
– integrated process-connections such as Tri-clamp, hose-pillar or threaded.
– different bore-diameters
– customer-specific mechanical mounting
– customer-branding / logo integration

PE flowmeter BKS clamp
PE-flowmeter body with integrated process-connection (BKS-camp)

Reason 2: Material-properties
The material-properties of PE are interesting for the applications we support.
First of all, PE is available in a FDA-approved version. This is a basic need for our Single Use Flowmeter Flowmax 242i
Secondly, the base-properties of HDPE offer a great portfolio of chemical resistance.
Thirdly, the standard HDPE can be upgraded to withstand extreme situations, see below for more details.

 

Improved material properties for PE-HD

High Density Poly-Ethylene (HDPE) has proven to be a useful basematerial for industrial components.

To achieve maximum performance, a treatment can be done to convert the material properties to a higher level.
The molecular structure of regular HDPE will migrate to a stronger 3D structure with an after-treatment. When electron-radiation is used, the improved material is named PE-Xc. (X stands for cross-linked, c represents after-treatment by electron-radiation.
In daily German operation, the HDPE-Xc version is also known as PE-HDV (V stands for ‘vernetzt)

Available flowmeters in PE-Xc

Flowmax offers a range of instruments in HDPE, most of them in PE-Xc upgrade as well.
Typically the Chemical Applications benefit from the increased properties. (Link in Dutch)

Flowmax 42i is the initiator of the HDPE-versions.
Main reason for its existence was a reduced bore-diameter in order to lower the measuring range for a pharmaceutical application.

PE flowmeter
Flowmax 42i with the typical darker colour of PE-Xc

 

 

 

Low-flow bore,customer specific process-connection and FDA-approved material came together in the design of the Flowmax 42i measuring tube.

The standard electronics have been integrated in the Flowmax 42i body.
Demanding applications can be fulfilled with the Flowmax 42i in PE-Xc material.

Quickly after approval of the Flowmax 42i, the pharmaceutical customer requested a Single Use version of this PE Flowmeter.

 

 

 

This Single Use request eventually resulted in Flowmax 242i M, a separate measuring tube out of FDA-approved HDPE, with remote electronics.

Flowmax 242i M separate measuring tube and electronics

 

For bio-pharmaceutical use, the standard HDPE is excellent.
The standard HDPE body is more white than the treated PE-Xc.

 

 

 

 

 

A third line in HDPE is the newest instrument, Flowmax 54i.
These instruments typically address higher flowrates such as cooling-circuits or high-volume chemical processes.
The three versions (DN32-40-50) are available in PE-Xc as well, making them optimally equipped for higher temperatures and mechanical wear when measuring abrasive slurries.

About MIB GmbH

MIB GmbH is the German company behind Flowmeister.nl where the ultrasonic flowmeters are developed, produced, calibrated and shipped.

Filling of vials with flow-control

filling of vials

Filling of 1 ml vials

Accurate volume control at high speed

Together with pre-filled syringes and ampoules, vials are the most common packaging for liquid pharmaceuticals.
When dispensing this valuable medicine, the dose-control is important for more than one reason:
– patients must get the right dose
– each drop which is given away costs money
– a detected error will have big consequences on the whole batch

Two important process steps

Delivering a properly filled vial merely depends on two actions.
Step one is adding the right volume in the vial.
Step two is verification that the dosed volume is really within specifications.

filling of vials
Filled vials, often the result of a process with single use components

Ways to check the vial filling result

There is more than one way to verify the content of a filled vial, and the best one is a weight verification.
Another method can be visual inspection of the fluid level in the vial.
Weight verification can be done fast and accurate and is the most common -and often prescribed- verification method.

The weight-verification should be no more than a verification. In a nominal process, 100% of the vials are verified and found to be ok.
However, not all processes are nominal and deviations may happen during the filling.
Weight-verification will detect any vial which is out of range. This is good for the customer, but affects production output and leads to reduced efficiency (OEE Overall Equipment Efficiency).

Raising OEE by reducing filling errors

The OEE-figure depends on availability of liquid and vials, the filling time and verification error-percentage.
Assuming there are enough vials and liquid, influencing OEE can only be done by the filling-time and accuracy.
By establishing a fast filling-process which flawlessly doses the right volume for each vial, the reject-percentage will be -close to- zero!

A capable flowmeter will be one of the key-components of such a fast-filling process.
Such an instrument can only be capable if speed and accuracy are inline with the process values.
(next to the measuring, a good PID-control, piping and actuator-valve are key components)

Capability by design

The ultrasonic flowmeter can be considered capable, this has been proven by validation and daily practice.
Capability is good due to the below properties of ultrasonic FlowMax instruments:

  • Flowmax delivers hundreds of measurements per second
  • Instrument body-sizing starts from DN3, (500 ml per hour)
  • The length of the measuring tube is maximized
  • The sonic path is optimized for low-flow accuracy
  • Smart algoritms process the raw measured data into a robust and stable signal

Speed can be increased by filling multiple vials in parallel. Field validation has proven this is still capable.
– Weight-verification will still be in place
– Rejects found are at ppm-level.
– PID, Piping and Actuator need to be capable as well

Disposable flowmeter

disposable flowmeter

 

The Disposable Flowmeter is a niche-product of which meanwhile multiple variants have become available in the market.
Diversity in the available solutions is good, since there is no universal solution that only has advantages.
Depending on your demands and wishes, it can be determined which type of single use flowmeter will suit your application best.
Below I like to menstion some aspects that are to be considered in the selection-process.

Demands and wishes

When starting to think about specifications, a number of aspects will come to your attention.
In this phase it is useful to separate the absolute demands from the more ‘soft’ wishes. Doing this will help you in a later stage where you might be forced to choose between possible solutions.
An example is de flowrange of the instrument. The current application will hae a lower limit and an upper limit. If the lower limit is a demand, please store it as such in your list. If a higher max flowrate may be useful in the future, write it down as a wish. It may very well be that a high flowrate instrument is available, but doesn’t offer the required accuracy in it’s lower measuring range.

 

Accuracy

Each type of instrument measures differently and with a different deviation.
Each method has in it’s physical form a maximum achievable accuracy. Deviation from the nominal measured value results in a process-deviation.

It’s up to you to determine wich level of accuracy is required.
When comparing, please be advised to ensure the unit of measure in which accuracy is expressed.
A 1% deviation of Full Scale (FS) can be completely different from a 1% of  Measured Value (MV). This topic is further detailed in another chapter.
A high-end instrument such as Coriolis or Ultrasonic will prove it’s accuracy on the certificate of calibration.

Wetted parts

The socalled ‘wetted parts’ are all the internal parts of the disposable flowmeter that actually are in contact with the measured medium, zijn de onderdelen van het instrument die met het medium in aanraking komen.
In the example of a turbine-meter these are: housing, turbinenbladed, shaft, bearings and possible sealing material.
An electromagnetic flowmeter already has less wetted parts, but will always have a housing, metal electrodes and seals.
Coriolis- and ultrasonic flowmeters often have just one wetted part, the housing itself.
In the case of MIB Flowmax, the wetted material is an approved and resistant plastic. Here’s an example of a Suppliers certificate.

Gaps and dead-space

The main reason to go for a single use / disposable component is cleanliness or purity. Contamination in any form or shape is absolutely unacceptable.
The form and shape of your instrument affects the risk of contamination.
Gaps between components are potential hiding places for bacteria and other unwanted particles or even molecules. Presence of sharp edges and corners or bearing points means an increase of risk. 
Free-bore instruments are always the better option, electromagnetic, Coriolis and Ultrasonic have a comparable ranking.
When considering all details like number of gaps, surface roughness and dead-space, the all-plastic one-piece housing of the ultrasonic disposable flowmeter scores best.

 

Costs

The financial aspect will remain an aspect in the total ranking.
In cases where cost is the most important factor, a turbine-meter will be the better option compared to more advanced instruments.

single use flowmeter
Price-differences between  flowmeters are less important in environmts like this.

Bio-pharmaceutical processen have risks which financially have hundreds or thousands times the impact of the instrument value.

Those riscs can partly be prevented by selecting the right equipment for your process.

A clean instrument, free of moving components and with only one wetted part, which reliably measures with high accuracy -even in pulsating flow- is always good value for the money!

 

 

 

Save money by replacing only the neccessary

In  MIB‘s strive to always do the maximum possibe in your advantage, also the cost-impact has been considered.
By designing the instrument with a separate measuring tube, the wetted parts can be exchanged whilst leaving the electronics in place.
In fact it is a single use flowmeasuring tube rather than a single use flowmeters. By providing factory-calibrated measuring tubes, including a dongle with the unique calibration details, you’re ensured of the original accuracy.
In case of a process-change, the nominal bore-size of the measuring tube can be replaced by another size and the matching dongle takes care of the accuracy.

This smart design is freely available and saves you €1.500,= per exchange!

Flowmeter chemie en chemicaliën

flowmeter chemie

<English version here>

Het veilig en gecontroleerd laten verlopen van chemische processen gaat nagenoeg altijd gepaard met gecontroleerde flow.
De top drie van het eisenpakket bestaat uit:
– Veiligheid
– Betrouwbaarheid
– Reproduceerbaarheid
De ultrasone flowmeter voor chemie toepassingen geeft een robuuste invulling aan deze drie eisen. Daarnaast is het instrument nog eens lekker snel en zeer nauwkeurig.

Flowmeter chemie draait om materiaalkeuze

Elk aspect van een ontwerp is belangrijk, maar voor de chemie flowmeter is materiaalkeuze cruciaal te noemen. Wanneer de ‘wetted parts’ niet voldoende resistent zijn voor het te meten medium blijft er niets over van veiligheid en betrouwbaarheid. Over reproduceerbaarheid hoeven we het dan al niet eens meer te hebben……
De ultrasone chemie flowmeter van MIB GmbH is geen one-size-fits-all, daarom is er een reeks van instrumenten met verschillende bouwvorm en materialen.
Er zijn enkele overeenkomstigheden in de verschillende reeksen:
– Kunststof behuizing
– Vrije doorlaat
– Geen bewegende delen
– Glad binnenoppervlak
-Geen electroden of metalen, slechts één wetted part

Enkele voorbeelden

PSU polysulfon flowmeter chemie

 

 

De basisreeks is vervaardigd uit PolySulfon (PSU)
Deze kenmerkende glanzend zwarte behuizing wordt middels spuitgieten vervaardigd.
Inzetbaar voor veel doeleinden, maar bijvoorbeeld niet voor Chloor.

 

 

 

 

 

PVDF flowmeter chemie

 

De echte chemie flowmeter is de Flowmax 400, uitgevoerd in PFA heeft deze reeks een enorm breed inzetgebied. Beschikbaarheid is beperkt tot de wat lagere flowrates. Ook de Flowmax 400 body is een spuitgietproduct met uiterst glad binnenoppervlak.

Standaard zijn flare procesaansluitingen, adaptor naar schroefdraad is als optie beschikbaar.

 

 

 

PE flowmeter chemie

 

Hogere flowrates tot 900 l/min zijn mogelijk in de Flowmax 54i reeks. De materiaalkeuze is hierbij gegaan naar PE-HD vanwege goede eigenschappen in laag-agressief milieu.
Flowmax 54i is ook verkrijgbaar in extreem bestendig PE-Xc 

 

 

flowmeter chemie Flowmax 242i

 

Als laatste variant is de Flowmax 242i beschikbaar, deze variant heeft ook een PE behuizing en mag in biochemie en biofarmacie toegepast worden.

Niet zomaar een kunststof dus, maar het resultaat van een geheel gevalideerd en gecertificeerd traject.
Het mooie aan het ontwerp is hergebruik van de standaard PSU behuizing voor de elektonica, terwijl de meetbuis als ‘wetted part’ uit de -noodzakelijk- speciale kunststof vervaardigd is.

Flowmeten of doseren in de chemie -> begin met goed advies 

Kennis is er om te delen.

Doseren kleine hoeveelheid vloeistof

doseren kleine hoeveelheid vloeistof

Hoe kleiner het volume, hoe belangrijker de nauwkeurigheid.

Voor het juist doseren van vloeistoffen waarbij u hoge nauwkeurigheid wenst, is een goede volumemeter het overwegen waard.
Een actieve meting van het exact gedoseerde volume, welke vervolgens gelogd kan worden verhoogt uw zicht op de processen.

Doseren kleine hoeveelheid vloeistof in ampullen en vials
De hoeveelheid medicijn in een vial moet juist zijn

In een doseerproces waar bij een klein volume nog steeds een hoge nauwkeurigheid verlangd wordt speelt de volumemeter een belangrijke rol.
Natuurlijk moeten uw pomp, leidingwerk en vulnozzle goed gedimensioneerd zijn, maar de hoofdrol ligt bij de flowmeter.

De ultrasone flowmeter is op dit gebied in het voordeel ten opzichte van veel andere types, en wel om een aantal redenen.
Ten eerste vanwege de hoge meetsnelheid, met 250 metingen per seconde worden de belangrijkste fluctuaties in de actuele flow waargenomen.

Een twdoseren kleine hoeveelheid vloeistofeede voordeel is de absolute nauwkeurigheid die ook bij lage flows behaald wordt.
Juist bij lage flows is dit vaak een aandachtspunt.

Door het instrument uit te voeren met een -vrije- doorlaat van 5 mm is er toch nog een relatief hoge vloeistofsnelheid.
Doordat de meetbuis relatief lang uitgevoerd is ondervindt het ultrasone signaal maximaal effect van de flow, dat komt de meetnauwkeurigheid ten goede.

Het streven naar een steeds lagere ondergrens leidt tot verfijning.
In de nabije toekomst zal een DN3 uitvoering ter beschikking zijn waarmee tot een halve liter per uur gemeten kan worden.

 

Het instrument werkt zonder bewegende delen, er is dus geen enkel effect van massatraagheid bij stop/start gedrag van de vloeistof.

Trillingen uit de omgeving zijn niet van invloed zoals dat bij bijvoorbeeld een Coriolis flowmeter het geval is. Ook is het prijskaartje een stuk gunstiger in vergelijk met Coriolis.

dosering kleien hoeveelheden

 

De afbeelding toont de Flowmax 42i van MIB GmbH
Met de kleinst beschikbare doorlaat van DN3 en een meetfrequentie van 250 metingen per seconde bent u verzekerd van nauwkeurig doseren van kleine hoeveelheden vloeistof.

Aandacht voor thermisch design en werking van het koelsysteem

PE flowmeter chemie

Aandacht voor thermische aspecten is in elk design van belang.
Onderstaand artikel uit Mechatronica & Machinebouw benadrukt nogmaals de invloed van een goed thermisch ontwerp in de -high tech- machinebouw.

Lees hier het artikel

Dwing invloed af!

Thermische stabiliteit is geen toeval. Onderdeel van een goed thermisch ontwerp is de sturing die u aan warmte kunt geven.
Door te bepalen waar de onvermijdelijke energie naartoe gaat kunt u ook invloed uitoefenen op de afvoer van deze energie.
Wanneer de afvoer vervolgens geforceerd kan plaatsvinden bouwt u extra zekerheid in uw thermische balans.

Meten is nog steeds weten.

Toepassing van actieve koeling met een vloeistofgevuld koelcircuit is een effectieve manier om overtollige warmte af te voeren.
De effectiviteit is eenvoudig te meten door een continue registratie van de temperatuur.
Daarbovenop is de koelwatertemperatuur en het debiet inzichtelijk te maken met één instrument: een flowmeter.
Terugkoppeling van gemeten waarden en een passende PID-regeling houden de temperatuur binnen de grenzen die u zelf stelt!

Met deze hoofdlijnen verzekert u zich van twee zaken:

  1. een stabiel proces met voorspelbare uitkomst en minimale spreiding
  2. onmiddellijke waarschuwing wanneer de koeling aan effectiviteit dreigt in te leveren

Het juiste instrument borgt een goed thermisch design van uw koelsysteem

Koelsystemen bevatten vaak gedemineraliseerd water, een niet-geleidend medium.
Twee voor de hand liggende instrumenten om flow en temperatuur te meten zijn in dit geval de Vortex-flowmeter en de ultrasone flowmeter.

Optie Vortex

Omdat de Vortex-flowmeter werkt door het opwekken van vortices krijgt u trillingen in het koelsysteem. Zolang dat niet nadelig is en u aan een globale meting voldoende hebt zou een Vortex-meter een goede optie kunnen zijn.
Let er wel op dat u zich goed laat adviseren, want dimensionering is bij dit type instrument cruciaal. Bij lage flows is de Vortex-vorming namelijk niet mogelijk en meet u niets.
Meestal is een Vortex-meter in aanschaf goedkoper dan een ultrasone flowmeter.

Optie Ultrasoon

De ultrasone flowmeter combineert een vrije doorlaat met een trillingsvrije meting én een hoge nauwkeurigheid over het hele flowbereik. Ook bij lage en schommelende debieten is de nauwkeurigheid uitstekend, een factor 5 tot 25 beter dan Vortex (afhankelijk van de flowrate en volle schaal waarde, lees hier meer over).
Temperatuurmeting is inclusief en u kunt grenswaarden aan het debiet koppelen zodat uw systeem een alarmsignaal krijgt bij onder- of overschrijding van ingestelde limieten.
Naar wens voert u het instrument uit met display en zijn er diverse kalibratieprotocollen te bestellen.

Flowmax 54i is een reeks ultrasone instrumenten wat bij uitstek geschikt is voor bewaking van u w koelcircuit. Tot een maximale flowrate van 900 liter per minuut zit u goed.

Laat u vakkundig en snel informeren door uw procesgegevens en vraagstelling hieronder te delen!

Uw instrument is getest en daarvan ontvangt u een certifikaat bij de levering. Optioneel is een kalibratiecertifikaat 3 meetpunten, of is een 8-punts kalibratie mogelijk.

thermisch design koelsysteem

Extraatje ingebouwd

De ultrasone flowmeter heeft nog een ingebouwd extraatje. Zoals de Vortex niet zonder trillingen kan werken, zo zal de ultrasone flowmeter automatisch detecteren of gasvorming in het vloeistofsysteem aanwezig is.
Gas is een slechtere warmtegeleider dan vloeistof, dus de aanwezigheid daarvan meldt Flowmax u graag terug!
Instelbaar, snel, betrouwbaar.
Uiteraard!
