low volume flow meters

Choosing the correct flow meter is the option of selecting the wrong one means nothing but trouble. There are a lot of flow meters to select from for every kind of application. The correct flow meter is important for crucial data collection; the wrong one may lead to grief in the budget with costly lost production time.

In this article, you get to know some of the essential elements that go into a flow meter’s decision-making process—putting into account the differences in volume- with mass flow measurement. Read below to know how you can easily select a flow meter for your application.

Flowmeter categories based on fluid

Several flow meters cannot measure gases or slurries. Other flow meters may be easily eliminated as they do not work with the application. But, the electromagnetic flowmeter may not work with hydrocarbons and requires a conductive liquid to work well. Below are various main flow meter categories paired with the fluid type the meters can handle.

Fluid Properties

It is difficult to know the properties of the fluid being determined, below are some of the major components:

  • Type of fluid – liquid, gas, slurry, vapor
  • Density
  • Viscosity
  • Temperature
  • Pressure
  • Condition of the liquid – foreign objects in it, suspended items, air bubbles,
  • Other contaminants

Physical Properties

It is also essential to know about the physical dynamics of the application site. Other physical conditions of the site you should consider are:

Configuration of the pipe before and when the flow meter and the length of straight pipe at the inlet and outlet of the flow meter are completed.

The size of the pipe. Other flow meters have a poor performance having very small pipes, although some cannot detect fluids in larger pipes.

The product the pipe is made from

The surrounding environment with whether it is stable or variable

Will the flow meter operate at a certain angle? This may seriously affect a flow meter’s working.

Flowmeter Specifications

Some specifications have to be taken into consideration when choosing the right flow meter.


Naturally, an essential factor of a flow meter is accuracy. But, not all flow meters have the same accuracy; some applications do not even need precision. To even recommend that accuracy is a variable seems ridiculous. Who would need an inaccurate meter?


Repeatability shows the number of times (%) you get similar results running the same test or measurement under the same conditions. Accuracy needs repeatability, though repeatability does not need accuracy. It just requires consistency. Therefore, it may also be said that the repeatability of a flow meter is mostly taken even more important than accuracy.

Turndown Ratio or Rangeability

This implies the range that a flow meter may accurately detect the fluid. Generally, choosing a flow meter using the basic range found without compromising some more critical products is best.

Hygiene Requirements

Flow meters for food, pharmaceuticals with the medical industry mostly demand sterile environments.


As stated above, this may need installation, maintenance, and repairs over time. How much is the meter price to work? Like its electrical demands, it can also add the overall cost of the flow meter.

As you can see, there are many variables to finding the right flow meter, and the ones we have listed are only the basics. This will not even touch on some ways in separate models. The best option to get the correct flow meter is to find assistance with your search by team up with experts in the field—experience matters.

It is essential to find your information from people who know these complex with basic devices. To let Bronkhorst support in the search for the correct flow meter for your requirements.

Choosing a Flow Meter Based on Type.

Each type of flow meter is suitable for a particular type of application or fluid. Selecting the best type is difficult because the accuracy of the measurement depends majorly on this factor.


The above are common important ways to choose low volume flow meters are price and popularity. You should know the basic two most common ways which people tend to use in the selection process. 

 Several principles of operation with design variations and thins to follow while carrying out installation parameters, location, and the economies of operation.
