Remote Type Vortex Steam flow Meter

A device used to measure the flow rate of steam in a steam system is a remote type vortex steam flow metre. It is based on the theory behind the phenomena of vortex shedding, in which a fluid passing by a bluff body (also referred to as a vortex shedder) generates alternating vortices downstream of the body. Since the frequency of these vortices is inversely related to the fluid velocity, the flow rate may be determined.

These are the parts of a remote type vortex steam flow metre:

2. Sensor/Transducer: A sensor or transducer is affixed to the metre, however it is situated far from the flow pipe. The vortices produced by the bluff body are picked up by this sensor, which then transforms them into an electrical signal.

3. Signal Processing Unit: A signal processing unit receives the electrical signal from the sensor and analyses it to calculate the frequency of the vortices.

Vortex steam flow metres of the remote type have benefits such non-intrusive flow measurement (no direct fluid contact), low-pressure drop, and comparatively little maintenance requirements. They are frequently used in industrial applications such as steam distribution systems, power plants, refineries, and others where precise steam flow measurement is crucial for process control, energy management, and efficiency improvement.
