CALIBRATION PROCEDURE FOR FLOW RATE OF DIFFERENTIAL PRESSURE METERS AND VOLUME DEVICES OF THE DISCHARGED VOLUME SCOPE OF APPLICATION The calibration rig within VCS is intended for measurements conducted by means of the flying start method, when the flow prior and immediately after the measurement remains steady. The route design accommodates the weight (gravimetric) method of measurement with collection of water in weight tank and the volume (volumetric) measurement method using reference electromagnetic flow meters. It is exceptional for its parameters: • the length of gauges subject to calibration (approx. 45 m), • the basic clearance of DN 500 pipeline system, • the option for installation of gauges up to DN 1400 • the use of hot water up to 80 °C.
