Product Description

Structure and working principle

It consists of waveguide wire, active magnetic and electric, which transmits pulse signals and receives back signal. When the pulse generator in the electric probe produces electric impulse, the pulse transmits to 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 with the speed of light. When the pulse magnetic field meets the float magnetic field, they form helical magnetic field and produce instantaneous torsion, that torsion forms torsion wave which returns to the electric probe at velocity of sound which lead the two ends of coil produce induced pulse. By measuring the time difference of between electric pulse and return torsion wave we can calculate the measured liquid level precisely. If a temperature sensor is added to the measuring tube, we can measure also the liquid temperature.
