Product Description

General Introduction
Transmitter Added to Magnetic Level Indicator is a new type of level transmitter with high accuracy.
It can be installed outside of the magnetic level gauge tube as a set, to realize high accuracy liquid level measuring and remote transmitting.
Structure and Working Principle
It is consist of waveguide wire (tube), active magnetic and electrics which transmit pulse signal and receive the returned signal. When the pulse generator in the electric probe produced electric pulse, the pulse transmit on the waveguide wire, at the same time, pulse produce a magnetic field which is around and perpendicular to the waveguide wire, the magnetic field transmit on the waveguide wire at speed of light. When the pulse magnetic field meets the floater magnetic field, they formed helical magnetic field, and produce instantaneous torsion, that torsion forms a torsion wave return to electric probe at velocity of sound which lead the two ends of coil produce induced pulse. By measuring the time difference between electric pulse and returned torsion wave, we can calculate the measured liquid level precisely. If add temperature sensor into the measuring tube, we can know the liquid temperature.
