ABSTRACT:
An upright metallic pipe, which extends into the supply of liquid in a vessel adjacent to a conduit for a float with a permanent magnet which rises and falls with the upper level of liquid, contains an elongated flexible body having an impermeable insulating sheath and an insulating web in the sheath. The web carries a row of electric resistors and an adjacent row of electric switches which are connected with a level indicating instrument. The switches are actuated by the magnet to thereby change the number of resistors which are connected with the instrument. The flexible body can be withdrawn from the pipe and converted into a small package consisting of overlapping convolutions. Such conversion involves flexing the web in the regions between neighboring switches. Such regions are traversed by flexible conductors which connect the neighboring switches and/or resistors to each other.
