Thermal Mass Flow Meter

 

Thermal mass flow meters belongs to mass flow meters which mainly have two kinds of flow meters, one is thermal mass flow meters,and the other is Coriolos mass flowmeter for fluid.Thermal mass flow meters is initially designed for gas,but now fluid thermal mass flow meters are also available.

 

Some useful links

1.Patent about ABB thermal mass flow meters

http://www.freepatentsonline.com/7650783.html

From the links, it can know the information about ABB thermal mass flow meters.A thermal mass flow meter is disclosed with at least one heating element which is mounted on a holder and immersed into a vessel with a flowing medium, wherein the holder is subdivided into two zones of differing thermal conductivity, the holder substantially having a high thermal conductivity adjoined by a short zone of low thermal conductivity in which the heating element is arranged.
