An in-ground tank measuring system for monitoring the level of fuel in a plurality of tanks. A float is provided in each tank connected by cable to a biased take-up reel connected to a potentiometer. A palm-sized monitor with provision to switch from one potentiometer has a switch to select the tank to be monitored, supply the reference voltage, receive the wiper voltage, and produce a liquid crystal digital display of fuel level.
