Stainless Steel Immersion Level Gauge Panel Mount Liquid Level Measurement Instrument

The immersion level gauge is a widely used liquid level measurement instrument in both industrial and civil fields. By being directly immersed in the liquid, it accurately and continuously monitors the liquid level through principles such as pressure or capacitance.

• Sensor probe: Usually made of stainless steel or titanium alloy, with an internal pressure-sensitive element.
• Gas-conducting cable: Used for pressure transmission and signal transmission, featuring waterproof and corrosion-resistant properties.
• Transmitter/display: Processes signals and outputs standard signals, with some models supporting remote monitoring and alarm functions.

• Water treatment and environmental protection: liquid level monitoring in urban water supply, sewage treatment, sedimentation tanks, reservoirs, rivers, etc.
• Industrial fields: liquid level measurement in chemical storage tanks, reaction vessels, industrial water tanks, oil tanks, etc.
• Food and pharmaceuticals: liquid level control in aseptic tanks, condiments, beverages, etc.
• Resource extraction: geothermal wells, mines, groundwater monitoring.
• Agricultural irrigation: liquid level management in water towers, reservoirs.

• Still water environment: Directly immerse the probe at the bottom of the liquid, and fix the cable at the opening of the container.
• Flowing or stirred environment: Insert a steel pipe with an inner diameter of approximately Φ45mm (with several small holes) into the liquid, and place the probe inside the steel pipe to reduce the influence of fluctuations.
• Avoid interference: The installation location should be away from the liquid inlet and outlet, agitators, and vibration sources.
• Cable protection: Avoid excessive bending, and the bending radius should be greater than 10 centimeters. Use steel wire for shock absorption if necessary.
• Anti-clogging design: The probe should be kept at a certain height from the bottom of the container to prevent silt from clogging.

1. Regular Cleaning: Clean the sensor diaphragm with trichloroethylene or alcohol once a month to prevent scaling or biological fouling; in the food industry, use a CIP system (pressure ≤ 3MPa, temperature ≤ 80℃).
2. Sealing Check: Inspect the cable interface and flange seal every quarter, replace aged fluororubber sealing rings, and ensure the insulation resistance is > 20MΩ.
3. Temperature Monitoring: In extreme temperature environments, use an infrared thermometer to monitor the sensor temperature, and the temperature difference with the medium should be < 5℃.

1. Signal Fluctuation: May be caused by poor cable shielding or diaphragm blockage. Check if the grounding is reliable and clean the diaphragm.
2. Zero Drift: Caused by environmental temperature changes or aging of silicone oil. Recalibrate the zero point and check the temperature compensation parameters.
3. No Signal Output: Check the power supply voltage (24VDC ± 10%) and whether the HART communication protocol is matched. If a fault code is displayed, replace the circuit board.

With the advancement of Industry 4.0 and Internet of Things (IoT) technology, submersible level transmitters are evolving towards intelligence and integration, supporting remote monitoring, data analysis, and fault diagnosis, further enhancing the accuracy and convenience of liquid level measurement.
