Daniel^®Compact Prover

A technology that verifies accuracy of a petroleum measurement meter, the Daniel^® Compact Prover is a leading choice of customers with fiscal flow measurement applications seeking excellence in meter calibration for laboratory or field installations.

Multivariable electronics enable mass proving as well as volumetric master meter proving. Small size, low weight and a 1,000:1 turn-down flow range make the product ideal for truck or trailer mounting. Customers also have the freedom to use a single prover for various meter sizes.

Wherever used, the Daniel^® Compact Prover reduces cost of field calibration, cost of disposal and risk of cross-product contamination.

One design element features piston assembly with internal poppet valve. Additional features include optical position sensing, hydraulic piston return, pneumatic piston actuation and advanced electronic data processing. The result brings to the customer a complete, packaged proving system significantly reduced in size, weight and cost.
