High Precision Good Safety Magnetostrictive Liquid Level Meter
Magnetostrictive Liquid Level Meter Working Principle
When the magnetostrictive liquid level meter works, the pulse generator in the electronic warehouse sends out an initial pulse. When the initial pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire. When this magnetic field meets the permanent magnetic field in the floating ball, a magnetostrictive effect is produced, causing the waveguide wire to twist to generate a constant-speed mechanical wave. The mechanical wave propagates in two directions, the mechanical wave reaching the end of the measuring rod is absorbed by the damper, and the mechanical wave transmitted back to the direction of the electronic warehouse is sensed by the energy pickup mechanism installed in the electronic warehouse, and converted into corresponding current pulses, the energy pickup mechanism After calculating the time difference between the two pulses, the height of the measured liquid level can be accurately measured.
