Product Description

The submersible pressure level transmitter utilizes high-performance pressure-sensing chips, combined with advanced circuit processing and temperature compensation technology. At different depths, the sensor experiences varying pressures, which are converted into corresponding current signals, enabling precise measurement of liquid level depth.

This product features a stainless steel housing for corrosion resistance and can be directly immersed in the measured liquid. It can accurately measure a wide range of substances, from water and oil to highly viscous slurries. It demonstrates excellent performance in applications such as river water level measurement, reservoir level measurement, water supply level monitoring, urban groundwater level monitoring, and water treatment tank monitoring.
