Abstract: An innovative design of a water level sensor is reported in this paper. The proposed design is suitable for high precision measurements usually required in sensing the water level of dams, tanks & reservoirs. This paper employs a reflected float mechanism in the presented design which helps in sensing the level to be measured. The proposed sensor design has a simple, reliable and low cost design concept and ease of installation. For precise measurement, the presented design has been calibrated and tested for level measurement up to 225 cm and corresponding error have been considered. The error is under acceptable limits i.e. within 2 % of the measured value. The improvement in the precision value has been also reported in the paper. The design is suitable for measuring level in the range of 0.1 cm and it can be improved further as per the requirement, by simply varying the circuit parameters. Steps utilized to develop the presented design have been also mentioned to clearly present the design concept and required setup.


Keywords: Level sensor, Measurement, Sensor design, Water level measurement.
