Flow Meter Calibration: 3 Best Practices You Should Be Aware Of

Before you can calibrate your flow meter, it’s important that you understand how they work. A flow meter measures the amount of fluid moving through a pipe or conduit, and it can be used to track anything from water usage to air pressure.

Flow Meter Calibration are based on turbine-like designs that use pressure differentials to calculate the amount of liquid passing by them. However, these devices have been known to have errors in their measurements due to factors like temperature variations and turbulence caused by bends in pipes (which increase friction).

As such, it is important that your flow meters be calibrated regularly so that you can maintain accurate readings. Here are three best practices for calibrating your flow meter:

Choose the right flow meter design for your needs

For example, if you need your flow meter to measure a low-flow process (less than 1 liter per hour), choose a design with a high range. However, if you need it to measure high-flow processes (more than 10 liters per second), then pick one that has higher accuracy and measurement uncertainty.

Additionally, take note of the sensor type used by the flow meter as this can affect its accuracy. For example, some models use strain gauge sensors while others employ temperature compensated thermistors. Lastly, check each model’s pressure rating and temperature rating as well so that they’re compatible with your process environment.

For instance, if your process involves high pressure and temperature levels, then pick a model with high ratings. In addition to the above points, make sure that the flow meter is easy to install and maintain. This way, you won’t have any trouble using it in your facility once it arrives.

Flow Meter CalibrationUnderstand how a flow meter works and how different fluids affect it

You need to know that there are two types of flow meters: positive displacement meters and turbine meters. And each type has its own method of measuring liquid flow rate. Positive displacement meters count the number of times the fluid passes through an orifice (like a pipe), while turbine meters measure rotational speed and calculate volume over time.

As for viscosity, it’s a measure of how hard it is for one substance to move against another when they’re in contact with each other.

For example, if you have molasses (a very viscous liquid) flowing through your pipes, then there wouldn’t be much friction between this substance—and thus no resistance against its movement down those pipes—but if you were using water instead, then there would obviously be more friction because water isn’t as thick as molasses!

But just because you understand how flow meters work doesn’t mean they’re easy to install. In fact, there are a lot of components that need to be working in unison for a proper installation—and if any one of them is missing or damaged then your meter might not be accurate at all!

Conduct calibration with an accredited calibration lab

It is important to calibrate your flow meter with an accredited lab. Accredited labs are qualified to calibrate the specific flow meter and have the right equipment to do so. They have also been trained on how to use that equipment properly, which ensures that they can conduct a calibration with high accuracy and precision.

Calibration is very important. It ensures that your flow meter is giving you accurate readings at all times, which in turn ensures that you are accurately measuring the fluid flowing through it and therefore able to make decisions based on those measurements.


In conclusion, we hope that this post has helped you understand the importance of flow meter calibration and how to ensure your meters are always accurate.
