A wireless system for liquid level measurement

Abstract

A wireless system for liquid level measurement is presented. It is developed in order to meet stringent power consumption requirements, but without sacrificing the accuracy of the built-in pressure sensor. The communication is realized using Bluetooth modules. An alternative solution based on radio units for 10.4 GHz is also discussed. The receiver is a personal computer with both the radio module and the appropriate software for reception and presentation of the acquired data. The developed wireless sensors have, a very high performance/power consumption ratio.
