Abstract

PURPOSE: To make it possible to measure a liquid level accurately and continuously by permitting a float, having the 2nd coil and an electronic circuit incorporated, to fluctuate with the level of a liquid along a bar-shaped body wound with the 1st coil helically.
CONSTITUTION: Float 5 having a through hole in the center penetrates conductive bar 1 wound with the 1st coil 2 and has the 2nd helical coil 6 and the electronic circuit, shown by being encircled with the broken line, provided internally. Interrupted wave A from driver 3 is supplied to the 2nd coil 6 by way of the 1st coil 2 and AC electric current generated by the 2nd coil is smoothed by rectifying circuit 7. With the electric current, transmitter 10 is put into operation and the 2nd AC electric current, electromagnetically coupled and sent out through the 2nd and 1st coils 6 and 2, is led from the 1st coil to detector 4 and then processed there, so that the value of the relative distance from one terminal of the 1st coil to a random point of the 2nd coil will be measured.
