Small Volume Provers

Simplifying field calibration

The Compact Prover provides high accuracy, rapid operation and continuous flow for proving a flow meter in an operational line. This is accomplished without interrupting normal flow and without the use of manually operated bypass valves.

Its unique design features a patented 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 while equaling or exceeding the performance of conventional provers.

The Compact Prover offers flexible mounting configurations on a truck or trailer for field proving of flow meters, or can be permanently installed in a testing facility either vertically or horizontally.

Pulse interpolation electronics permit exact time determination and pulse counting which provides high accuracy proving with a smaller volume and fewer flow meter pulses than any previous prover technology. The use of a small displacement volume is made possible by the high resolution of the Compact Prover which is attributed to two major factors; precision optical switches, and data acquisition using double chronometry.
