At the end of 2014 in accordance with contractual terms the project on manufacturing of Mechanical Displacement Meter Prover 180 ANSI 300 (1st rate) and Test Measure 500 liters was completed. Mechanical Displacement Meter Prover is a technological unit, consisting of a calibrated section, loading and receiving chambers, piston detector switches, system of draining pipeline, washing and air removal systems connection devices, pressure and temperature measuring gauges. Technological system is mounted on the metal base. Mechanical Displacement Meter Provers are designed for verification (calibration) of different types of flow transducers by multiple transferring of a definite fluid volume. Test Measure is a calibrated tank with sight glass and scale of tolerance. Test Measure is designed for checking the volume of the calibrated section of the pipe prover by comparing the volume of displaced water from the pipe prover into the test measure and the volume measured with the help of the test measure.
