Master Meter Gas Flow Calibration System

ఉత్పత్తి వివరణ
The master meter method gas flow standard device adopts four high-precision gas turbine flowmeters produced by Elster GmbH, Germany.These flowmeters serve as standard instruments for the calibration of other flowmeters. The device operates with air as the medium and employs the negative pressure method to achieve the calibration of the flow meters under test.
