Compact Prover / Small Volume Prover

Fast, repeatable meter proving in a compact design built for dependable performance in custody-transfer applications.

The Brodie Compact Prover provides high accuracy, rapid operation and continuous flow for proving a flow meter in an operational line. Designed per API MPMS Chapter 4 standards, the Brodie Compact Prover can be utilized to verify the accuracy of almost any liquid flowmeter type, including positive displacement, turbine and manufactured pulse meters.

Proving is accomplished without interrupting normal flow and without the use of manually operated bypass valves. The unique design features a piston assembly with an internal poppet valve in conjunction with optical position sensing, hydraulic piston return, pneumatic piston actuation and modern data processing techniques. The result is a complete packaged proving system significantly reduced in size, weight and cost that ensures accurate and repeatable proving performance.
