Flow Calibration Systems

SV METER(Critical nozzle)

       The inherent characteristics demonstrated by gas flows in the sonic region (critical flows) are used in this type of flowmeter. Because of their high degree of accuracy and reproducibility, they find uses, as the standard meter, in calibrating other flowmeters for gas service. And the property of producing a constant flow is used in running a performance test of various gas-service flow control equipments.
