Abstract:
A simple and reliable approach has been made to calibrate and certify Air, Oil or Gas-operated Dead Weight Pressure Tester (DWPT) against a Reference Dead Weight Pressure Tester, Periodic calibration data of dead weight pressure testers of different ranges and make has been collected against a reference DWPT traceable to the National Physical Laboratory, UK and NIST (NBS) USA. Using these techniques, the uncertainties of calibrated DWPTs have been found within their limits of error as specified by the manufacturer. The method has been found suitable for the certification of oil, gas, air-operated Dead Weight Pressure Testers using oil-operated DWPT as reference standard.
