Operating principle of thermal mass flow meter

This measurement principle is based on the fact that heat is removed from a heated body when a liquid flows past it. Thermal mass flow meter is a flow meter based on the principle of thermal diffusion. That is, when a fluid flows through an object, the amount of heat loss from the heat-generating object is proportional to the speed of the fluid flow. SI-RSL Thermal Mass Flow Meters Specifically, the sensor sensor has two standard RTDs. One for the heat source and one for measuring the liquid temperature. As the fluid passes through, the temperature difference between them is nonlinear with the flow of the pond. The meter can turn this relationship into a linear output that measures the flow signal. There are two ways to design flow meters based on the principle of thermal diffusion: one is based on the principle of a constant temperature difference. The other is based on the principle of constant power.

Thermal mass flow meter. Peculiarities

This article is about using or inserting a thermal vitratomer for gas or wind suppression. Gas mass loss suppressor is an ideal solution for gas suppression from small pipelines to large pipelines, canals or stacks. We can carry out the recovery of liquefied gas, compressed air, CO2, biogas, natural gas, O2, BF gas (blast furnace gas), combustion air, industrial wind, flare gas, He gas, nitrogen gas, etc. Thermal vitratomers of various types are installed in various galuzes of industrial gas supply, in the container of a micromass vitratomer, microtemperature, high-temperature, linear device-sensor of a thermal mass vitratomer.
