Knowing the Different Flow Meter Specifications

Flow Meter Specifications

When it comes to choosing flow meters, one size definitely does not fit all. There are different things that you would have to consider when choosing one, and specifications are definitely one of the most important.

Below, we will discuss what specs you should look into when getting a flow meter. Whether you are going for an insertion type flow meter or a mag flow meter, you definitely have to be wary of these things to make sure you are getting the right one.


The rangeability or turndown ratio implies the range that your flow meter can measure. It would be best if you can choose a flow meter that has the greatest range available, as well as one that would not compromise other critical components.


The main purpose of measuring a unit — whether it’s gas, liquid, air, or energy is to get an accurate measurement so you would be able to compute and list everything down properly. Having an accurate reading can lead to huge problems, especially if you are trying to measure for an industrial company that handles huge units and measurements.

Nobody wants an inaccurate meter and thus, you should see to it that the flow meter that you are getting is of high-quality and can handle heavy measurements. However, you should note that not all applications require precision, but still, you should aim for getting the right measurements at all times by getting an accurate flow meter.


The costs should not determine how well a flow meter works. Some flow meters are simply affordable while some can be super expensive. It all depends on the manufacturer, but, in the end, it should boil down to how well it actually works.

The costs should cover the installation and maintenance, so you should make sure to ask the manufacturer and the seller if there are extra costs for such. Buying a flow meter that involves both installation and maintenance will help you save tons of money in the long run.

Also, certain factors such as electrical demands can increase the total cost of the flow meter.


When measuring units, you would want to make sure that you are getting the correct results no matter how many times you do it. This means you have to measure the units over again. If the flow meter is giving you the same exact measurements, then you have yourself a high-quality meter. Make sure that the results will be consistent, though, as the repeatability of a flow meter is often considered more important than accuracy itself.

Hygiene Requirements

If you are measuring units for pharmaceuticals, food, or the medical industry, then you would want to make sure that your flow meter can handle measurements in a sterile environment. These industries are often sensitive when it comes to contamination.

These five factors or specifications are very important when it comes to flow meters. Discuss them with the manufacturer before actually getting one so you’d know you are getting a good deal.
