Purpose of the development: Hydrostatic level sensors are designed to conduct long-term monitoring of water level and temperature in water reservoirs, water storage basins, lakes, rivers and geological engineering wells.

The development stage readiness: Pre-production model is made

Description of the development:
()
The hydrostatic pressure exerted on the isolation membrane of the pressure module and the temperature of the case are converted to analog electrical signals. Further, the signals are transmitted to a precision multichannel analog-digital converter with a built-in instrumentation amplifier that provides a high degree of resolution. After the amplification and conversion to digital code, the signals from the ADC come to the microcontroller. The programming of the microcontroller and the program correction are performed through a separate access connectors. The exchange of data on water level and sensor temperature with the information system is mediated by an RS485 interface (Modbus RTU protocol). Using a system of data collection and transmission via the GSM network, it is possible to monitor the condition of wells and reservoirs in real time scale, which will give the possibility to rapidly respond to changes in the level and temperature of groundwater. The table also lists the specifications of one of the best analogue, i.e., a DL/N high-precision hydrostatic sensor (STS, Switzerland). Comparing and analyzing the engineering data of the TPH and DL/N sensors, we can state for certain that the basic percentage pressure error for the developed sensor is almost 5 times less than that of the DL/N sensor. This will make it possible to determine the change in the water level in boreholes with accuracy better than 1-2 mm.
