BTMF thermal type gas mass flowmeter is designed on the basis of the principle of thermal diffusion, the use of fluid flow through the external heat source heating pipe when the temperature field changes to measure fluid mass flow, or by heating fluid fluid temperature rise a certain value, the amount of energy needed and the relationship between the fluid quality to measure fluid mass flow rate of a flow meter. Without pressure and temperature compensation, the mass flow rate of natural ga
■ Measurement of gas mass flow without temperature and pressure compensation.
■ Large range ratio, measuring flow rate range: 0.1m/s~120m/s.
■ No pressure loss, suitable for arbitrary shape of pipeline with known cross-sectional area.
■ Corrosion resistant sensor, suitable for measuring corrosive gases.
■ Plug-in sensors can be installed and maintained online.
■ he expert algorithm of full range ensures the accuracy of measurement. Suitable for trade settlement or gas leak detection.
