Installation UPSG for verification and calibration of gas meters
For metrological support of verification of gas meters, the enterprise manufactures UPSG verification installations using critical nozzles as references.
The installations are intended for controlling gas meter parameters (sealing, relative gas volume measurement error, threshold sensitivity and pressure loss).
The installation principle of operation is based on creating a reference volumetric flowrate in the work channel and measuring it, and comparing the value with the readings of the meters being verified.
The installations are equipped with PCs for automating basic meter verification operations, including printout of test protocols.
Verification installations UPSG by JV Radmirtech are functioning effectively in the cities of Kharkiv, Theodosia and Mukachevo.
