Explosion proof natural gas LPG gas Biogas thermal gas mass flowmeter flow meter
The application of thermal gas mass flowmeter flow meter in natural gas mainly includes the following aspects:
1. Gas metering and quality control: Thermal gas mass flow meter can be used for gas metering to ensure accurate
measurement of natural gas flow. This is crucial for flow control and energy management of natural gas pipelines.
2. Natural gas extraction and gathering: In natural gas wellheads and gathering pipelines, thermal gas mass
flowmeters can measure the mass flow of natural gas to ensure the stability of extraction and transportation
process. Especially in harsh environments such as offshore natural gas extraction platforms, this flowmeter can
provide reliable data support.
3. Natural gas filling station: In automobile filling stations and industrial gas filling stations, thermal gas mass
flowmeters are used to measure and control the mass flow of natural gas during the filling process to ensure the
accuracy of the filling amount and prevent safety problems caused by natural gas leakage or flow out of control.
4. Energy exchange and leakage test: In the oil and gas industry, thermal gas mass flowmeters are also used in
energy exchange, leakage gas testing and other scenarios to ensure the quality of natural gas and the accuracy of
energy exchange.
Working principle: The thermal gas mass flow meter uses the principle of heat diffusion for measurement. The
sensor consists of two reference-grade thermal resistors (RTDs), one for heating (velocity sensor RH) and the other
for measuring the temperature change of the gas (temperature sensor RMG). When the gas flows through, the
heated sensor takes away heat, causing its temperature to drop, and the gas flow rate is calculated by measuring
this temperature change.
