What is the highest accuracy of mass flow meters for high-pressure gases? Where in the country can it be calibrated?
Thread Content
Where in China can high-pressure gas mass flow meters be calibrated? Which brands offer better precision and stability? I am looking to purchase a high-pressure gas mass flow meter. If anyone knows, please recommend it; a private message is also fine
There are 2 options available for high-pressure gas mass flow meters: 1. High-pressure Coriolis mass flow meter； 2. High-pressure thermal gas mass flow meter. Therefore, please specify the name of the gas? Work stress? Temperature? Traffic range? (Should the flow rate at standard conditions be displayed in Nm3/h or mass flow rate in Kg/h?) Traffic accuracy? Only then can I recommend which type of mass flow meter would be suitable for you? And where to calibrate it? It’s high-pressure, and the calibration cost is quite expensive.
Emerson, Siemens, Yokogawa. Calibration certificate, provincial metrology institutes (quality inspection and quarantine)

Most CNG refueling stations use high-precision Coriolis flow meters； Calibration can be carried out at metrology institutes in various provinces; in-use foam generators are usually calibrated on-site.
