Sincerity high accuracy thermal mass flow meter emerson function for the mass flow

What is a thermal mass flow meter?

The rotameter emerson product is able to guarantee constant productivity. It can be frequently upgraded, which can offer the desired functionality during operation.

Gas flow is almost exclusively measured with thermal mass flow meters. Using one or more temperature sensors, the meters measure the amount of heat dissipated by introducing heat into a flowing stream. This method works best when measuring the mass flow of gas.

In general, a thermal mass flow sensor/controller can be used for other fluids. However, it is important that the suitability of the sealing material used for the new gas or liquid is ensured beforehand.

The thermal meter is almost exclusively used for gas flow applications. This method works best when measuring gas mass flow, as it introduces heat into a flowing stream and measures how much heat is dissipated by using one or more temperature sensors.

Working Principle of Thermal Mass Flow Meter 

Thermal mass flow sensors use the thermal dispersion principle which allows for the rate of heat absorbed by a gas to be directly proportional to its mass flow. In a typical thermal flow meter, flowing gas absorbs heat and cools the source. As flow increases, more heat is transferred to the gas, leading to an amount of heat dissipated from the source that is proportional to both the gas's mass flow and its thermal properties. Through measuring this heat transfer, it is possible to work out a mass flow rate. These meters are designed to accurately measure mass flow rather than volumetric flow, in clean gases that are not affected by temperature changes, pressure levels, viscosity or density. Therefore, corrections do not need to be made for these conditions.
