Pipeline thermal gas mass flowmeter

Thermal gas mass flowmeter is a flow instrument designed based on the principle of thermal diffusion. Its working principle is to utilize the proportional relationship between the amount of heat lost by the heating object and the fluid flow rate when the fluid flows through it. The sensors of this series of flow meters have two standard level RTDs, one used as a heat source and the other used to measure the fluid temperature. When the fluid flows, the temperature difference between the two is linearly related to the flow rate, and this relationship is then converted into a linear output of the measured flow rate signal through microelectronic control technology. The head of the pipeline type thermal gas mass flowmeter is made of stainless steel and carbon steel material, which is anti-corrosion and moisture-proof. The chip has effective protection with three anti chip mounting, anti interference circuit design, anti lightning protection circuit design, anti surge, efficient anti…
