1. Product Overview
The Smart TLC-2101-WL is a non-contact ultrasonic liquid level sensor designed for high reliability and ease of installation and maintenance. It measures liquid levels without direct contact with the medium, making it suitable for various applications such as water tanks, rivers, and sewage systems.
The sensor operates by emitting ultrasonic pulses (Tx) and receiving the reflected pulses (Rx). The time-of-flight (TOF) of these pulses is used to calculate the distance (d) to the liquid surface using the formula: d = (C x t) / 2, where C is the velocity of sound in air and t is the time taken for the pulse to travel to the surface and back.

3. Setup and Installation
3.1 Important Installation Notes
- Power-up Sequence: Always power up the display unit first, then connect and power the sensors. Incorrect power-up sequence may prevent proper operation.
- Pipe Installation: If installing the sensor on a pipe, ensure the pipe is a single, continuous piece without splices. No debris should be present on the inner wall of the pipe, as this can interfere with measurements.
3.2 Component Overview
3.3 Power Connection
Connect the provided DC 9V power adapters to the display unit and the sensor. Ensure the correct plug type (US, UK, EU) is used for your region.
3.4 Sensor Mounting
Proper sensor placement is crucial for accurate readings. Refer to the diagrams below for optimal installation positions.
- The sensor should be mounted in the middle of the tank, away from any liquid inlets, to prevent false readings caused by turbulence or incoming flow.
- Ensure the sensor is held perpendicular to the liquid surface.
- Avoid installing the sensor too close to bulkheads or tank walls, as this can cause strong pseudo-echoes and inaccurate measurements.
- The required hole size for mounting the sensor is 72mm.
4. Operating Instructions
4.1 Display Unit Functions
- Display State Switching: Toggles between 'Always On' and 'Display for 10 seconds' modes.
- Set Button: Used to enter settings menus and confirm selections.
- Model Switching: Cycles through different display modes or data views.
- Plus (+) Button: Increases values or navigates up in menus.
- Minus (-) Button: Decreases values or navigates down in menus.
- Real-time Levels: Graphical representation of the liquid level in the tank.
- Time Display: Shows the current time.
- Tank Temperature / Distance: Displays the temperature of the tank's contents or the distance from the liquid level to the sensor probe (in °C/M).
- Ambient Temperature: Shows the temperature of the environment where the display unit is placed.
4.2 Alarm Function
The device is equipped with an alarm function that will emit an audible beep when the liquid level reaches pre-set high or low thresholds. This feature helps in preventing overflows or critical low-level situations.

5. Maintenance
To ensure optimal performance and longevity of your Smart TLC-2101-WL sensor and display unit, follow these general maintenance guidelines:
- Keep the sensor and display unit clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the units to extreme temperatures or direct sunlight for prolonged periods.
- Regularly check all connections to ensure they are secure.
6. Troubleshooting
If you encounter issues with your Smart TLC-2101-WL, consider the following:
- Device Not Functioning: Ensure the display unit is powered on before the sensor. An incorrect power-up sequence can prevent the system from working.
- Inaccurate Readings: Check the sensor's installation. Ensure it is in the middle of the tank, perpendicular to the liquid surface, and away from liquid inlets or bulkheads. Verify there is no debris on the inner wall of pipes if installed in such a manner.
- Low Display Brightness: The display unit may have adjustable brightness settings. Refer to the operating instructions (Section 4.1) and use the 'Set', 'Plus', or 'Minus' buttons to navigate and adjust display parameters.
7. User Tips
- Optimize Sensor Placement: For the most accurate readings, ensure the sensor is mounted centrally and vertically above the liquid, avoiding any obstructions or turbulent areas.
- Brightness Adjustment: If the display appears dim, check the settings menu on the display unit for brightness adjustment options.
- Mobile App Connectivity: Please note that this specific model (TLC-2101-WL) primarily uses the dedicated LCD display for monitoring and does not feature mobile app connectivity. Other models, such as the TLC-2206, may offer app integration.
8. Frequently Asked Questions (FAQ)
- Q: How do I adjust the screen brightness?
- A: Use the 'Set' button to enter the settings menu, then navigate with the 'Plus' and 'Minus' buttons to find the brightness adjustment option. Confirm your selection with the 'Set' button.
- Q: Does this sensor connect to a mobile app?
- A: The Smart TLC-2101-WL model does not support mobile app connectivity. It is designed for monitoring via its dedicated LCD display unit.
9. Warranty and Support
The Smart TLC-2101-WL Wireless Ultrasonic Water Level Sensor comes with a 3-year warranty from the date of purchase. For any technical assistance or warranty claims, please contact your retailer or the manufacturer directly.
