System for the determination of the speed of rotation of a body, especially of the turbine of a flowmeter

Creators

Description

The device comprises a small magnet and a magnetometric sensor with a thin magnetic layer producing in a magnetic field an electric signal. The rotation speed is given by the frequency of this electric signal. The system is used for flow rate determination in PWR type reactors
