Product Overviews

Kaifeng Instrument TGK-100 thermal gas mass flow meter is a kind of thermal dispersion or immersible mass flow meters comprise a family of instruments for the measurement of the total mass flow rate of a gas fluid in closed pipelines. 

It features no moving parts, nearly unobstructed straight through flow path, require no temperature or pressure corrections and retain accuracy over a wide range of flow rates. Straight pipe runs can be reduced by using dual-plate flow conditioning elements and installation is very simple with minimal pipe intrusions.

Features And Functions


● Measuring the mass flow or volume flow of gas;

● Do not need to do temperature and pressure compensation in principle with accurate messurement and easy operation;

● Wide range:0.5Nm/S~100Nm/S for gas.The meter also can be used for gas leak detectino.

● Good vibration resistance and long service life.No moving parts and pressure sensor in transducer,no vibration influence on the measurement accuracy.

● 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).

● Digital design,high accuracy and stability.

● Configuring with RS485 or HART interface to realize factory automation and integration.

Industry Applications

The thermal measuring principle is widespread in industry and is being used successfully in many applications with gas flow, for example:

  • Compressed air (consumption, distribution)

  • Carbon dioxide (for beverage production and chilling)

  • Argon (in steel production)

  • Nitrogen and oxygen (production)

  • Natural gas (for burners and boiler feed control)

  • Air and biogas measurement (e.g. in wastewater plants)
