 Critical Flow Sonic Nozzle Gas Flow Calibration Device

The LSJ Series Critical Flow Sonic Nozzle Gas Flow Calibration Device (hereinafter referred to as the "Device") utilizes critical flow Venturi nozzles that conform to national standards (GB/T21188-2007/ISO9300:2005) as standard flowmeters. It is classified as a standard measurement flow calibration device.

This series of devices meets the calibration and verification needs of various instruments. It features multiple temperature and pressure measurement interfaces in accordance with national calibration regulations for velocity-type and volumetric flowmeters, enabling the calibration and periodic verification of gas flowmeters including turbines, vortex meters, rotary meters, swirl meters, orifice meters, and industrial diaphragm meters.

The series boasts a modular design with key units that can be skid-mounted, offering advantages such as high uncertainty level, wide measurement range, high degree of automation integration, and significant energy savings in the power source.

It is suitable for manufacturers with a diverse range of flowmeters and large quantities, as well as calibration and verification units that require high accuracy and low uncertainty in the overall device performance.
