Category: Thermal Mass meters
Thermal mass flow meters, also known as thermal dispersion or immersible mass flow meters, are for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits. The operation of thermal dispersion mass flow meters is attributed to L.V. King who, in 1914, published his famous King’s Law revealing how a heated wire immersed in a fluid flow measures the mass velocity at a point in the flow. Industrial-grade thermal dispersion mass flow meters were introduced in the 1950’s and 1960’s.
