Analysis of additive in a liquid level process using multi sensor data fusion

This paper presents a technique for analyzing the amount of additives added to the liquid, whose level is to be controlled. The objective of the proposed work is to design a technique which will (i) measure level of liquid independent of solution, (ii) analyze the quantity of additives present in the solution and (iii) design a multi sensor framework to achieve objectives (i) and (ii). Capacitive Level Sensor (CLS) and Ultrasonic Level Sensor (ULS) are used for measurement of liquid level. Respective data conversion circuits are designed to convert output of both the sensor to a standard signal (voltage). For incorporation of Multi Sensor Data Fusion (MSDF) Joint Defense Labortory (JDL) framework is considered. Once the system is designed it is tested with data. Results obtained shows successful implementation of proposed work.
