A thermal gas mass flowmeter measures the mass flow rate of gas directly, utilizing the thermal properties of the gas. The thermal gas mass flowmeter utilizes a heated sensor to measure the cooling effect of flowing gas, providing high accuracy and repeatability for a wide range of gases.
How Does A Gas Mass Flow Meter Work?
1. Heating Element and Temperature Sensors:
The core components of a thermal mass flow meter for natural gas include a heating element and at least one temperature sensor, though typically two sensors are used. These components are positioned in the flow path of the gas.
2. Constant Temperature Differential:
In one common design, the meter maintains a constant temperature difference (ΔT) between the two temperature sensors by adjusting the power to the heating element. The amount of power required to maintain this temperature difference is directly proportional to the mass flow rate of the gas.
Sensor One is placed upstream of the heating element and measures the gas temperature as it enters.
