What is steam mass flow meter?
Steam mass flow measurement can be achieved by Coriolis mass flow meter or vortex flow meters or other DP flow meters. We here introduce vortex flow meters to measure steam mass flow.
Steam flow meter vortex type
Vortex flowmeter is a flow measurement instrument without moving parts. Vortex flow transmitters measure flow rate by measuring the vortex frequency downstream of obstacles in the flow path, so as to achieve the purpose of measuring flow. Vortex meters have a wide range of applications and measurement accuracy. It is a kind of flow measuring instrument developed in the 1970s. It has attracted attention as soon as it came out, and it has been paid more and more attention. It is a promising flow meter recognized by the domestic and foreign instrument industry.
Working principle of steam mass flow meter
In the vapor or steam flow measurement, perpendicular to the flow direction of the fluid, insert a bluff cylindrical object as a vortex generator. Within a certain range of Reynolds number, a regular oscillating motion will be generated behind the vortex generator, that is, in the vortex two rows of vortices will be generated on both sides of the generator, with opposite directions, alternating vortices. These two parallel rows of vortices are called Karman vortex streets. Vortex flowmeters use this principle to measure. However vortex flow meter measure steam volumetric flow, by introducing built-in industrial temperature sensor or pressure sensor , vortex flow transmitter totalizer steam mass flow .
