Liquid level sensor

The article reports an idea of using a simple, cantilever-type load cell with a rod as a level sensor for continuous liquid level measurements. The sensor is based on the principle of the Archimedes buoyancy principle. The density and geometry of the rod govern the choice of the load cell. The length of the rod is governed by the height of the tank. A series of cyclic tests have demonstrated a highly repeatable response of the sensor. The accuracy of this low-cost sensor is field tested and found to be {+-}0.5% of the full range, for a 10 m level of water in a tank, and is working reliably for the period of 18 months. The sensor range can be easily extended to lower and higher tank heights. The sensor is crowned by its easy installation and calibration.
