Overview

According to King's law of thermal effect, heating power P, temperature difference △T (TRH-TRMG) and mass flow Q have a definite mathematical relationship. P/△T=K1+K2 f(Q)K3 K1, K2, and K3 are constants related to the physical properties of the gas. The unique temperature difference measurement method of the thermal gas mass flowmeter overcomes the large zero drift caused by the water, oil and impurities in the gas when the thermal gas mass flowmeter adopts the principle of constant temperature difference to measure the gas flow, resulting in unmeasured Disadvantages. It can also be used to measure the mass flow of wet gas, such as real-time detection of the air volume (speed) in the mine gas drainage, air supply, and exhaust system.
