Pipe provers are used to verify or calibrate the measuring feature of positive displacement or velocity flowmeters in closed pipeline under working condition.The Bi-Directional Pipe Prover has proven itself over and over again as one of the most relia…
● It can prove or calibrate positive displacement type or velocity type flowmeters outputting pulse signal.
● As a movable flow proving centre,it can prove or calibrate the fowmeter with actual flow under the working condition;the error aroused by the different working condition and proving condition is overcome.
● It can carry out a real time dynamic leak hunting to the conversion valve of the pipe prover to satisfy the requirement of the international MAP.
● There needs no start and stop of the flowmeter in the course of proving or calibration;the error caused by the start and stop of the flowmeters is eliminated.
