General
SRK-M Micro-flowrate Thermal gas mass flow meter is designed on the basis of thermal dispersion, and miniature gas flow meter adopts method of constant differential temperature to measuring gas flow. It has advantages of small size, easy installation, high reliability and high accuracy, etc.

Features of ultra low gas flow meter

Measuring the mass flow or volume flow of gas in low flow rate ,at ml/min or cc/min
Miniature gas flow meters Do not need to do temperature and pressure compensation in principle with accurate measurement and easy operation.
Wide range: 0.5Nm/s~100Nm/s for gas. The meter also can be used for gas leak detection
Good vibration resistance and long service life. No moving parts and pressure sensor in transducer, no vibration influence on the measurement accuracy.
Microfluidic flow meter Easy installation and maintenance. If the conditions on site are permissible, the meter can achieve a hot-tapped installation and maintenance. (Special order of custom-made)
Ultra low gas flow meter with Digital design, high accuracy and stability
Configuring with RS485 or HART interface to realize factory automation and integration
