Overview

The gas mass flowmeter ensures the reliability and reliability of the instrument through the analysis of two principles and the use of professional technology. The instrument has two sensors, one serving as a heat source and the other measuring the temperature of the medium. When the fluid flows, the molecular weight of the fluid passing through the two sensors is proportional to the heat loss from the heat source, so we can calculate the fluid flow rate through an electronic module.
