RIM20 Rotor Insertion Flowmeter

RIM20
The RIM20 multivariable insertion turbine flowmeter utilises three primary sensing elements to measure the mass flowrate of steam, liquids and gases:

  • Turbine velocity sensor,
  • RTD temperature sensor,
  • Solid-state pressure transducer.

Insertion turbine flowmeters measure flow of liquid, gas, and steam by detecting the frequency of rotation of the turbine blades. According to the proven laws of physics, the frequency at which the turbine rotates is directly proportional to the flow velocity.
Insertion turbine flowmeters measure flow by detecting the local velocity at a strategically located position within the pipe. The RIM20 detects the frequency within the sensor head.
It uses the local velocity, along with other parameters such as fluid type, pipe size, and Reynolds Number to calculate the average pipe velocity, and consequently, the volumetric flowrate.
