Sonic Nozzle Method Gas Flow Calibration System
Price:
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.
The LNQ-3000 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. This device can be used for the calibration of various gas flow meters with diameters ranging from DN25 to DN200(including ultrasonic, roots, turbine, vortex shedding, etc.), covering a flow range of 0.5 to 3000m³/h.
Design basis:
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.
The core component of this Gas Flow Standard Device, the critical flow Venturi nozzle, is designed and manufactured by the company itself in accordance with ISO 9300:2005 "Measurement of Gas Flow Using Critical Flow Venturi Nozzles." It has been certified as compliant by the national legal metrology authority.
