Flow-metering calibration rig PURS-V-1
The PURS-V-1 unit is used for calibration of water meters with the upper measurement limit up to 217.2 mЗ/h. Value of the relative error of no more than 0.3%
The calibration rig operating principle is based on comparison of the results of simultaneous measurements of the calibration medium flow rate (volume), reproduced by the unit, flowmetercounter being calibrated and the reference measuring instrument, connected in series in measurement mainlines.
