A. Product Overview
The RDCLWLPSF Corrosion Resistant Hydrostatic Level Transmitter is designed to measure liquid levels by detecting the hydrostatic pressure generated by the liquid column above the submerged sensor probe.
The transmitter is particularly suitable for applications where conventional metallic level sensors may experience corrosion due to exposure to aggressive liquids or demanding industrial conditions.
The RDCLWLPSF features a corrosion-resistant housing available in polypropylene (PP) or polytetrafluoroethylene (PTFE).
These materials provide chemical resistance for suitable industrial liquids, including selected acidic and alkaline solutions, subject to chemical compatibility.

B. Working Principle
The RDCLWLPSF Corrosion Resistant Hydrostatic Level Transmitter operates using the hydrostatic pressure measurement principle, where the pressure produced by a liquid column is proportional to its height and density.
When the sensor probe is submerged in a liquid, the liquid above the probe generates pressure on the pressure-sensitive element.
The sensor detects this pressure and converts it into an electrical signal that represents the liquid level.
How It Works
1. Sensor Submersion
The RDCLWLPSF sensor probe is submerged inside a liquid storage tank, reservoir, wastewater collection tank or other compatible vessel.
The sensor is positioned at a suitable measurement point, generally near the bottom of the tank.
2. Hydrostatic Pressure Detection
The liquid column above the sensor generates hydrostatic pressure.
As the liquid level increases, the pressure acting on the sensing element increases. When the liquid level decreases, the pressure reduces.
3. Pressure Signal Measurement
The internal pressure-sensitive element detects the applied hydrostatic pressure and converts it into an electrical measurement signal.
4. Electronic Signal Processing
The transmitter's electronic circuit processes the pressure measurement and determines the corresponding liquid level using the configured measuring range and liquid density.
5. Output Signal Conversion
The measured liquid level is converted into the selected electrical output.
Available configurations include 4 to 20 mA, analog voltage outputs and RS485 communication.
6. Continuous Level Monitoring
The output is transmitted through the sensor cable to a compatible PLC, digital level indicator, data acquisition system or industrial monitoring controller.
C. Why Is the RDCLWLPSF Corrosion Resistant Hydrostatic Level Transmitter Used?
The RDCLWLPSF is used for continuous liquid level monitoring in industrial environments where corrosion resistance, submersible installation and automation compatibility are important.
Key Benefits
1. Corrosion Resistant Construction
The transmitter is available with PP or PTFE housing materials, providing resistance to various industrial chemicals when the selected material is compatible with the process liquid.
2. Continuous Liquid Level Measurement
The RDCLWLPSF provides continuous level measurements rather than only detecting predetermined high-level or low-level switching points.
3. Industrial Measurement Accuracy
The transmitter is specified with 0.5% full-scale accuracy, supporting industrial liquid level monitoring and process control applications.
4. Multiple Output Signal Options
Available output configurations include 4 to 20 mA, 0 to 5V, 0 to 10V, 0.5 to 4.5V and RS485.
This allows the transmitter to be selected for different compatible monitoring and automation systems.
5. Wide Measuring Range Availability
The RDCLWLPSF supports configurable measuring ranges up to 200 meters, allowing selection for different tank depths, reservoirs and liquid level measurement requirements.
6. IP68 Submersible Protection
The IP68 protection rating supports submerged operation under the specified conditions, making it suitable for industrial tanks and liquid reservoirs.
7. No Mechanical Moving Parts
The hydrostatic pressure sensing principle does not require moving floats, reducing mechanical wear associated with float-based measurement systems.
Common Applications
Industrial chemical storage tanks
Acid and alkali storage tanks with compatible materials
Wastewater treatment plants
Sewage collection tanks
Effluent treatment plants
Chemical neutralization tanks
Environmental monitoring systems
