BPG Bell Prover

​The BPG Bell Prover test bench is designed to test residential and commercial diaphragm meters from size G1.6 up to G160. These test benches are manufactured using bell prover technology and are suitable to be used in meter manufacturers’ plants or for laboratory utilities. The bell prover standard is a reference standard for air volumes. It is used as a volume reference standard for validating the pre-determined volumes of air needed to perform the calibration of verification of residential and commercial diaphragm gas meters.  The test bench generates the requested flow rates and compares the measured volume of the gas meter under test with the applied standard reference system.
