Calibration rigs

The range of portable calibration rigs allows calibrating utility and household meters of standard sizes from G1.6 to G65 inclusive. The meters, basing on different physical principles of measurement, present different requirements to the calibration rig's dynamic range. The dynamic range of SPU-3 rigs allows operating with any meter types: membrane, jet, ultrasonic, etc.

The rig is placed in a compact case, has an integrated power supply source and a printer. Calibration and protocol drawing-up are performed on site, without meter dismounting.

Stationary calibration rigs SPU-5 are used for calibration of gas meters with standard sizes from G1.6 to G40 inclusive. Calibration of gas meters is based on comparison of the results of simultaneous measurements of air volume by the gas meter being calibrated and by the rig. The result of volume measurements by means of the rig is adopted as the actual value.
