Abstract
For nearly a decade, liquid level sensors have been on the market as white food or beverage products, manufacturing, medical, residential, farming, automotive, aerospace, defense and liquid leak detection or level measurement devices. The nano material-resistive sensor based on reduced graphene oxide is highly sensitive and highly reactive to level measurement. This rGO liquid level sensor was developed, and using screen printing process, nano material film is printed on Al2O3 substratum. For safety purposes the sensor film was coated with Parylene-C. The rGO-based nano material was synthesized using Modified Hummer process. A linear relationship between the rGO film's resistances was observed due to the change in liquid level, which implies fast detection and therefore calibration. With its fast and cost-effective manufacturing process, this liquid level sensor has considerable potential in industries where liquid level sensing is mandatory e.g. pharmaceutical also, space, automotive and even for liquid storage, liquid levels using cryogenic fluids of H2O icewater, LCO2, LN2, LH2, LOX and LHe. © Published under licence by IOP Publishing Ltd.
