Abstract
A device for measuring the depth and temperature of a liquid stored in a tank is provided. The device includes a hermetically sealed vertically disposed tube having ultrasonic transmitter/receiver devices at either end thereof with a reflector vertically movable in the tube and having a through-hole therein permitting transmission from one end of the tube to the other as well as reflection. A float encircles the tube and moves up and down with the level of liquid in the storage tank. The float and reflector are magnetically interconnected so that the reflector moves up and down with the float.
