Introducció
The Briidea HRWL-01 is a non-contact freshwater tank level indicator designed for recreational vehicles (RVs), caravans, and boats. It provides real-time monitoring of your freshwater tank's level, allowing for timely refills and preventing empty tank situations. This system utilizes a non-contact detection method, ensuring the purity and hygiene of your fresh water by avoiding direct contact with the sensor.
The kit includes all necessary components for installation, eliminating the need for additional detection electrodes. This manual provides detailed instructions for the proper setup, operation, and maintenance of your Briidea HRWL-01 indicator.

Configuració i instal·lació
Proper installation is crucial for accurate readings. Please follow these guidelines carefully:
- Col·locació del sensor: Install the sensor in the middle of the water tank. Direct water contact with the sensor can affect measurement accuracy. Ensure the sensor remains dry during the calibration process.
- Dimensions del dipòsit: For optimal performance, the length of your water tank should be approximately twice its height. Verify that your tank dimensions are compatible with the product's requirements before installation.
- Material del dipòsit: Be aware that some metal water tanks may influence the accuracy of the measurement.
- Profunditat de detecció: The sensor supports deep detection up to 400 cm.

Instruccions de cablejat
The Briidea HRWL-01 operates on a DC power supply ranging from 7V to 32V. Connect the indicator according to the following diagram:
- Connect the positive (+) terminal of the indicator to the positive terminal of your 7-32V DC power source (e.g., vehicle battery).
- Connect the negative (-) terminal of the indicator to the negative terminal of your 7-32V DC power source (e.g., vehicle battery).
- Connect the sensor cable to the designated port on the indicator unit.

Calibració
After installation and wiring, ensure the sensor is dry before initiating any calibration steps. While specific calibration steps are not detailed, the system is designed to provide accurate readings once properly installed and powered. If initial readings appear inaccurate, re-verify sensor placement and ensure no water contact with the sensor during the initial power-up or calibration phase.
Instruccions de funcionament
Once installed and powered, the Briidea HRWL-01 indicator will display the current freshwater level in your tank.
- Pantalla LED: The indicator features a multi-color LED display that shows the water level in percentages (10% to 100%). Each LED segment illuminates to represent the corresponding water level.
- Power-Down Memory: The device includes a power-down memory function. This means that once the initial settings are configured, they are retained even after power interruptions or disconnections, eliminating the need for re-configuration.

Manteniment
The Briidea HRWL-01 is designed for low maintenance. To ensure continued accurate operation:
- Reviseu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
- Ensure the sensor unit remains clean and dry on its exterior surface. Avoid direct water contact with the sensor's detection area.
- Keep the display unit clean using a soft, dry cloth. Do not use abrasive cleaners or solvents.
Resolució de problemes
If you encounter issues with your Briidea HRWL-01, consider the following:
- Lectures inexactes:
- Verify the sensor is installed in the middle of the tank and is not in direct contact with water.
- Confirm that the water tank's length-to-height ratio meets the recommended 2:1 specification.
- If using a metal water tank, be aware that it may affect measurement accuracy.
- Ensure the sensor was dry during initial setup and calibration.
- Sense pantalla/alimentació:
- Check all power connections to ensure they are secure and correctly wired to a 7-32V DC source.
- Verifiqueu que la font d'alimentació estigui activa i que proporcioni el volum correctetage.
