      Installation manual for SENSE FL 4300

      February 2025
      The SENSE FL 4300 has two modes: fill level and load detection. This manual covers installation advice for both modes.
      Mounting the sensor
      All mounting options for your sensor can be found in the Sensolus product mounting instructions.
      Load detection
      Horizontal mounting
      When mounting the sensor horizontally for load detection:
      • Install the sensor in the middle of the load
      • Install in the middle of the cavity
      • Install the sensor so it has a 90° angle with the object it has to detect
      Do not install too close to the side and do not install at an angle. The radio signals can be obstructed and cause false sensor
      values.

      [www.sensolus.com](http://www.sensolus.com) | [info@sensolus.com](mailto:info@sensolus.com)
      February 2025
      Make sure there is a minimum distance of 10 cm between the top of the sensor and the load.
      Vertical mounting
      When mounting the sensor vertically for load detection, install with the arrow on the back of the sensor facing up.

      Fill level
      Mounting inside an asset
      When mounting inside a container for fill level detection:

      • Install the sensor in the middle of the container
      • Install the sensor so it has a 90° angle with the surface it has to detect
      Do not install too close to the side and do not install at an angle. The radio signals can be obstructed and cause false sensor
      values.
      Make sure there is a minimum distance of 10 cm between the top of the sensor and the load.
      Mounting outside an asset
      When mounting outside a container for fill level detection:
