Gas Meter Calibration Facilities APU-G-011
The company manufactures automated calibration facilities for gas meters APU-G of the following modifications:
Systems for verification of household meters;
Closed-cycle systems;
General industrial design systems.
The automated calibration system for gas meters APU-G is intended for verification (calibration) and research of turbine, rotary, ultrasonic, and vortex meters of natural gas, air, other gases, and their mixtures that have a pulse output signal, by the comparison method with reference meters. The working medium in APU-G systems is air.
Facilities can be used for conducting initial verification (calibration) of gas meters with limits of relative error of volumetric flow measurement ±1.0% and higher during release from production and after repair, as well as for conducting periodic verification of gas meters that are in operation.
