SLDL7120 (Hose Type) magnetostrictive liquid level gaug

Working principle
When MagScan Magnetostrictive Liquid Level Meter works, the circuit part of the sensor stimulates the impulse current on the waveguide wire. The current transmits along the waveguide wire, and the pulse current magnetic field is generated around the waveguide wire. The sensor rod of the meter is equipped a float, which can move up and down along the measuring rod along with the change of the liquid level. There is a set of permanent magnetic rings inside the float, and the magnetic field around the float changes when the magnetic field of the pulse current is encountered with the magnetic ring magnetic field generated by the float. Thus the waveguide wire made of magnetostrictive materials generates a torsional wave pulse in the position of the float. The pulse is transmitted back at a fixed speed along the waveguide wire and detected by a circuit. The position of the float (liquid level) is determined by measuring the time difference between the impulse current and the torsional wave.
