Sonic nozzle gas flow testing device in production

Sonic nozzle gas flow testing device is widely used to calibrate the gas flowmeters including vortex flowmeter, thermal mass flow meter, precession vortex flowmeter, gas turbine flow meter etc.  
We Q&T not only make flow meters but also make testing devices including liquid flow testing devices and also gas flow testing devices (sonic nozzle gas flow testing device). 
Below is the sonic nozzle gas flow testing device which is under production, it will be used for a famous testing institute. After production finished, we'll ship it to user's work site, and get national certificate.
