Meter Provers: Uses, Types, and Functioning ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Meter provers are flow meter calibration apparatuses used for analyzing readouts from a flow meter. By deploying these devices for flow meter calibration, required adjustments can be made. Readings obtained from a liquid or gas flow meter are authenticated and calibrated by deploying these advanced devices. Contemporary meter provers are automatic and take care of the whole process on their own as compared to manual provers of olden times.
So now that we know what is a meter prover and their use, let’s move on to understand how they work.
How do Meter Provers Work? Meter provers are deployed to detect changes in the amounts of gas/liquid flowing through a pipe at different times. Each prover has highly advanced sensors to capture any deviation in fluid or gas flow. The whole process ensures that meter readings remain accurate at all times. There are different prover types available in the market and you can choose the one that fits your needs the best. Let’s take a look at the different types of provers available in the market. ➢ Pipe provers Pipe provers are also known as sphere provers and ball provers. Functioning on the principle of continuously replicated displacements of liquid in fixed amounts, these provers help compare volumes so that necessary measures can be taken to correct the variations. When the fluid moves inside the ball prover, the attached meter makes the calculations. 1
