Product Description
Product Overview
This hydrostatic submersible water level sensor features a protective front-end cap that shields the sensor diaphragm while allowing smooth liquid contact. With waterproof cable and sealed housing, it ensures secure connections for long-term underwater operation.
Key Features
- Reverse polarity protection and transient overcurrent/overvoltage protection with EMI compliance
- High-quality vented cable designed for permanent water immersion
- Strong overload capacity and anti-interference performance for cost-effective stability
- Core auto-calibration algorithm prevents value fluctuations from water surface movement
- Sloped liquid inlet design prevents silt and debris entry while resisting impact
- Submersible probe measurement for easy installation
- Multi-layer protective structure with IP68 rating and corrosion-resistant stainless steel construction

Working Principle
The water level sensor operates based on the relationship between liquid hydrostatic pressure and liquid level (P = ρgH). It converts hydrostatic pressure into electrical signals to measure liquid levels. The sensor cable contains a vent tube connected to the external atmosphere, measuring both underwater and atmospheric pressure to calculate water depth based on pressure differentials.
When connected to a monitoring host, this liquid level sensor can control water pump and solenoid valve switching based on administrator-set water level data, enabling remote automatic control systems.
