When electrical pulse annular magnetic field meets with floater intrinsic magnetic field, both of the field vectors add together to form spiral magnetic field to produce instantaneous torque force and form a mechanical torque force wave on the aveguide wire to transfer back to electrical probe at a certain speed nso as to create induction pulse on both ends of the coil.
Through measurement of time difference between induction pulses produced by electrical pulse and torque force wave, it can accurately calculate the height of liquid level. Fixing high accurate temperature sensor in the measuring pole can measure medium temperature.
