Submersible Hydrostatic Level Sensor for Water/Oil/Fuel Tank, 4-20mA/RS485

Submersible hydrostatic level transmitters utilize the principle that the hydrostatic pressure of a liquid is proportional to its level. An internal pressure sensor measures the pressure generated by the liquid column and converts it into a level signal. Its core principle is Pascal's Law, achieving stable measurement by compensating for temperature and cable pressure changes.

Generally, they are suitable for various media such as water, sewage, seawater, groundwater, river water, and chemical liquids. If special materials such as PTFE or 316L are used, they can be used for mildly corrosive media or media containing impurities. For high-viscosity, high-temperature, or highly corrosive liquids, a dedicated model must be selected.

During installation, avoid proximity to turbulent areas such as pump inlets and water inlets to prevent errors; avoid friction between the probe and the pool wall; ensure the cable has sufficient slack; when installing in deep wells, it is recommended to use a guide steel pipe to prevent swaying; and add lightning protection devices if necessary.
