Gas Meter Calibration Test Bench

The ‘Calibration Standard’ of the Test Bench is “Bell Prover”, which is considered a Primary (Calibration) Standard to Test & Calibrate Domestic Gas Meters (& Gas Meters used in Hotels/Restaurants etc.). The device is ideal for OEMs, Calibration Laboratories & Calibration Service Providers.

The Test Bench, with 2 Sizes of Bell Prover (20L & 100L)will effectively cover Very Low (Qmin – typically 0.016 m3/h (0.27 LPM)) to Maximum (Qmax – 6 m3/h (100 LPM)) Flow Rates. Available Accuracies : 0.2% & 0.5% F.S.

Upto 4 Gas Meters can be connected (inserted) during a campaign. Facility provided for continuously monitoring Differential Pressures (DP) across each Meter as well as upstream & downstream Line Pressures & Line Temperatures. Line Pressures are regulated typically around 500Pa.

All the testing procedures are controlled by the PC and run automatically, the Test Results can be saved, printed.

Simple/Basic, Manual/Semi-Automatic Test Bench Models are also available. Test Bench frame is made of Industrial Aluminium with perfect outlook and strong structure.
