It is a high quality hydrostatic level measuring instrument, which is developed by introducing the advanced diffusion silicon pressure sensor and IC SENSORS circuit technology from NOVO company in the United States, and it applies the silicon fine etching process and silicon wafer lamination, which are two cutting-edge technologies in the world. It is widely used in petroleum, chemical, metallurgy, environmental protection, food, water conservancy, urban water supply, oilfield and other industries for liquid level measurement. The excellent quality of the hydrostatic level transmitter meets the need for high-precision liquid level detection instrumentation for industrial automation and metering automation of some industries in China.
