Abstract: Salinity measurement is important because it plays a significant role in measuring subsequent parameters like density etc. This method describes a method to measure the salinity of water using a capacitive transducer which has two parallel plate electrodes. The electrodes are immersed continuously in the water so that the area and distance between the plates don’t change. The change in capacitance is converted to a proportional voltage using Schering bridge. This can be analyzed under various conditions before made into a handheld device where the data can be stored. This method is simple and reliable which can be used for industrial purpose.
