Flow Meter Calibration System

A flow meter calibration system is a set of tools and equipment used to test, verify, adjust, and calibrate the accuracy of flow meters, ensuring they provide precise measurements of fluid flow rates.

Flow meter calibration systems can be designed to calibrate various types of flow meters, including Coriolis mass, Electromagnetic, Ultrasonic, Turbine, Vortex, and Positive Displacement meters, among others.

Yes, various national and international standards exist for flow meter calibration, such as ISO 4185. Compliance with these standards is often required for certain industries.

In the Gravimetric method, water (or fluid) is collected in collection tanks that are placed over high precision weighing scales. These scales have a high accuracy and resolution and hence we can accurately measure the total weight/mass of the fluid collected. From this and with the help of an online/offline density meter, we can get the density of the fluid and thus calculate the actual volume of the fluid that is collected with high accuracy.

Volume=Mass/Density

In the Comparison or Master meter method, the readings between the Reference (test) flow meter and a pre-calibrated meter known as the Master meter, typically Electromagnetic or Coriolis Mass flow meters are compared, and the error deduced by calculating the difference in reading in the test meter from the master meter and calibrate the test meter to match the master meter readings.
