Devices for determining water salinity based on inductive balance sensors

Abstract

For determining the salinity of drinking water, a two‑coil inductive balance sensor is proposed, while for grounded water bodies a three‑coil sensor is used. In the first case, the useful signal is displayed on a pointer indicator, and in the second case, it is output to a personal computer monitor. The paper presents the electrical circuit of the devices and graphs showing the dependence of the useful signal on the concentration of table salt in water.
