A prover system is required with each fiscal metering system to calibrate and prove the accuracy of the flow meters supplied. At MeTAS we offer a complete range of provers to compliment the selected metering technique, liquid properties, ergonomics and project requirements. Provers can be integrated into the metering package or mounted on a separate skid.

Types of commonly used proving systems are:

Bidirection, displacer type
Unidirectional, displacer type
Compact (Small volume) Piston Prover
Master Meter
