Mobile Proving Services

Westech is pleased to provide meter calibrations utilizing the Honeywell Small Volume Prover. Currently, we operate two Honeywell S-25 Provers with the max flow rate of 3570 BPH, 2499 GPM and 568 m3/h. The two mobile provers are trailer mounted allowing for broad coverage of the western United States, with one prover located in California and the other in Washington. Outfitted with two 12vdc deep cycle batteries that are wired in series to create 24VDC operating power, our provers can perform in the most remote locations.

Westech utilizes Prove-it 8 software to operate the provers and collect data from each meter proving that will meet each customer’s required measurement policy, along with State and Federal guidelines and tolerances. Our technicians follow the Westech company policy of .05% repeatability and .0020 factor variation between previous and current proving.
