📡 How does the TFSR fill level sensor work?

The TFSR sensor is a smart fill level sensor used to measure waste levels, particularly in underground containers. Many of our customers are already using it because this sensor is reliable, accurate, and low-maintenance.

🔍 What does the TFSR do?

• 1. Continuous measurement with radar:
  The sensor hangs at the top of the container and measures the distance to the waste. This is done using radar technology, which means that the measurements are not affected by dirt, moisture, condensation, or temperature differences.
• 2. Automatic calibration after installation:
  Once the TFSR is connected to the software (such as Suite), it automatically performs a zero measurement after the container has been emptied three times.
  
  With each emptying, the sensor recognizes that the container is empty. After three successful emptyings, it learns what an empty container 'looks like' from the inside. Based on that, it sets the correct zero point.
• 3. Settings and memory:
  The sensor saves this zero measurement in its internal memory. From that moment on, the sensor knows what the minimum (empty) and maximum (full) depth of the container is. Therefore, the measurements are extremely accurate from that point onward.
• 4. No manual calibration needed:
  Thanks to this automatic process, there is no need to manually enter settings or dimensions. The sensor adjusts itself to the specific container in which it is placed.

📤 Feedback to the configuration

After completing the calibration, the TFSR automatically sends its settings back to the configuration in Suite or Tardif. This includes information such as the measured depth of the container and the set zero measurement.

If a new TFSR is later placed in a container that previously had a sensor, the system recognizes this and the new sensor automatically receives the correct settings from the platform. This way, the measurement remains reliable without needing to be manually recalibrated.

📌 Why is calibration important?

Calibration ensures that the sensor knows what the lowest (empty) and highest (full) positions are. Without proper calibration, the measurements may deviate. Thanks to the self-learning system of the TFSR, this happens automatically, without manual adjustment.

• ✅ Accurate measurements, even with varying container heights.
• ✅ Fewer error messages or incorrect fill level percentages.
• ✅ No manual entry of depths or dimensions needed.
• ✅ New sensors automatically take over existing settings.
