Selecting the right flow meter is the key to success while selecting the wrong one means nothing but trouble. There are a lot of flow meters to choose from for every kind of application. The right flow meter is essential for crucial data collection and the wrong one can lead to grief in the budget and costly lost production time.
In this blog I will discuss some of the important elements that go into the decision-making process of a flow meter, taking into account the differences between volume- and mass flow measurement. Read below how you can more easily select a flow meter for your application.
The most common criteria to select a flow meter are: price and popularity. Beware of relying on two of the most common criteria that people tend to use in the selection process: cost and popularity. If you place price at the top of your criteria, it will be easy to get the wrong flow meter for the application or one that does not hold up physically or performance-wise. That bargain will quickly turn into a budget nightmare.
If the measuring device and its ancillary equipment need frequent and expensive maintenance, what you saved on that flow meter will quickly dissipate. Moreover, a flow meter that has a higher initial investment can also make up for it by costing less to maintain and operate. Coriolis mass flow meters are more expensive in purchase initially than many other types of flow meters, but can save a great deal of money over time because they are easier to maintain, translating into less downtime.
While it is important to research what type of flow meter is most commonly used in your industry, just selecting what is popular can also lead to disaster. If the flow meter is not appropriate for the application, measurements can be under or over which means valuable material can be lost and revenue negatively impacted.
Advances in technology can also put instruments on the market that may not be as well-known, but provide a better solution. For instance, in the past, inline ultrasound flow meters had to be re-calibrated when a new fluid was introduced and could not be used in applications where hygiene was important. Nowadays new ultrasonic flow meters have solved those concerns and opened up the use of inline ultrasound flow meters to those types of applications.
A flow meter is a highly technical device that is influenced by lots of variables. We’ll breakout the most important ones, but realise that every application is unique.
There are two basic measurements of fluids, volume- and mass flow measurement, so a flow meter is either a volumetric flow meter or a mass flow meter. However, you can calculate volume from mass and mass from volume if you know the density and agreed upon variables. Whether a volumetric flow meter or mass flow meter is the best depends on the application, its components and the purpose of the measurement.

Some flow meters can be easily eliminated because they simply will not work with the application. For instance, electromagnetic flow meters will not work with hydrocarbons and require a conductive liquid to function. Many flow meters cannot measure gases or slurries. Listed below are some of the main flow meter categories paired with the fluid type the meters can handle.
It is crucial to know the properties of the fluid being measured, below are some of the primary components:
It is also important to know about the physical dynamics of the application site. Some of the physical properties of the site to consider are:
Read in this blog why piping important is for thermal mass flow meters
Flow meters for food, pharmaceuticals, and the medical industry especially demand sterile environments.
As stated above, this should include installation, maintenance and repairs over time. How much the meter costs to operate, like its electrical demands, can also increase the overall cost of the flow meter.
As you can see, there are a lot of variables to finding the right flow meter and the ones we have listed are only the basics. This does not even touch on the various options in different models. The best way to get the right meter is to get help with your search and team up with experts in the field. Experience matters.
It is important to get your information from people who know these complex and important devices. To let Bronkhorst help in the search for the right flow meter for your needs, please contact us.
