PRODUCT DISPLAY
Working Principle
Thermal gas mass flow meter is designed on the basis of thermal dispersion, and adopts method of constant differential temperature to measuring gas flow. It has advantages of small size, easy installation, high reliability and high accuracy, etc.
The meter contains two platinum resistance temperature sensors. The thermal principle operates by monitoring the cooling effect of a gas stream as it passes over a heated sensor, Gas flowing through the sensing section passes over two sensors one of which is used conventionally as a temperature sensor, whilst the other is used as a heater
The temperature sensor monitors the actual procesvalues whilst the heater is maintained at a constant diferential temperature above this by varying the power consumed by the sensor, The greater the gas velocity, the greater the cooling effect and power required to maintain the differential temperature, The measured heater power is therefore a measure of the gas mass flow rate.
FEATURES
-Oxygen,nitrogen, hydrogen, chlorine and multi-component gas measurement.
-Blast furnace gas, coke oven gas measurement.
-Natural gas, liquefied gas, flare gas, and other gas flow measurement.
-Primary and secondary air flow measurement of power plant blast furnace.
-Flow measurement of underground mine ventilation or exhaust system.
-Flue gas measurement.
-Compressed air measurement.
