Product Description

Product Description

Thermal Gass Mass Flowmeter

Thermal flowmeters are flow meters designed based on the principle of thermal diffusion. Due to their wide measurement range ratio, resistance to on-site pipeline vibration, and relatively short installation requirements for straight pipe sections, they are increasingly favored by the market and are widely used in multiple fields

CHARACTERISTIC

1,Convenient installation, simple maintenance bidirectional detection, anti-vibration up to 24 points of flow measurement 
2,Output analog calibration multi-point non-linear curve correction 
3,Wide-range ratio of 100:1 
4,Flow and temperature detection at the same time, switching the display 
5,Large-diameter small-flow measurement, can be done to detect leakage 
6,Using proprietary technology "double balance structure" encapsulated sensors 
7,Proprietary high humidity, high temperature algorithms, medium temperature up to 300 ℃ direct mass flow detection, without temperature and pressure compensation

PRINCIPLE

Thermal flowmeter is a flow meter designed based on the principle of heat diffusion. That is, when a fluid flows through a heating object, the amount of heat dissipated by the heating object is in a certain proportional relationship with the flow rate of the fluid. The sensor of this series of flowmeters has two standard-grade RTDs, one for heat source and the other for measuring fluid temperature. When the fluid flows, the temperature difference between the two is linearly related to the flow rate. This relationship is then converted into a linear output of a flow measurement signal through microelectronic control technology.
