Module 14. Propulsion

A fuel flow transmitter requires a motor or a synchronous motor to have a

  • constant voltage within small tolerances
  • constant frequency within small tolerances
  • low EMF as it is immersed in fuel

Explanation

A fuel flow transmitter that uses a synchronous (mass-flow) motor relies on the motor turning at a precisely fixed speed to provide the reference against which the impeller's drag is measured. Synchronous motor speed is set by supply frequency, so a constant frequency within tight tolerances is essential for accuracy; voltage is far less critical.

Mihir Somaia asking:

Can someone please explain.

most basically motor or syncro motor rotates on a fixed speed (mean fixed frequency) to give the fuel to non changing flow on a pipe,after that the fuel with constant flow hits a turbine which spring loaded, turbine rotates slıghtly from original position by that fuel force and that change measured as fuel flow,
