  • How Does a Thermal Flowmeter Work?

    A thermal flowmeter works by measuring the total mass flow rate of a fluid flowing through a pipe or duct. In a thermal flowmeter’s simplest working configuration, fluid flows past a heated thermal sensor and a temperature sensor. As the molecules of the fluid flow past the heated thermal sensor, heat is lost to the flowing fluid. The thermal sensor cools down while the temperature sensor ...
