Tips: How does a hydrostatic submersible level sensor work?
A Hydrostatic Submersible Level Sensor measures liquid level by detecting the hydrostatic pressure generated by the liquid column. The pressure changes according to the liquid density and depth, following the principle of P = ρgh. The built-in pressure sensor converts the detected pressure into standard electrical signals such as 4–20mA, voltage, or RS485, allowing accurate liquid level monitoring through PLCs and control systems.
