Sonic Nozzle Method Gas Flow Calibration System

Sonic nozzle gas flow test device is used to test and inspect vortex flow meter,turbine and ultrasonic flow meters at wide flow range.Keep your flowmeter's measurements as accurate as their specifications.

LNQ Sonic Nozzle Gas Flow Standard Device is a gas flow standard device (negative pressure method) that utilizes a critical flow Venturi nozzle as a standard meter. It is designed, manufactured, and installed in accordance with various relevant calibration regulations, including JJG643-2003 "Calibration Regulations for Standard Flow Standard Devices," JJG620-2008 "Calibration Regulations for Critical Flow Venturi Nozzles," JJG633-2005 "Calibration Regulations for Gas Volume Flow Meters," JJG1030-2007 "Calibration Regulations for Ultrasonic Flow Meters," JJG1029-2007 "Calibration Regulations for Vortex Flow Meters," JJG1037-2008 "Calibration Regulations for Turbine Flow Meters," JJG577-2012 "Calibration Regulations for Diaphragm Gas Meters," and others.
