    LoRaWAN open protocol and is compatible with the LoRaWAN protocol. R718PE uses ultrasound to detect the distance between the device and the detected object. The medium the device detects is the air, so the detected object can be any liquid or solid that has a flat and horizontal surface, water level.

  • Page 4: Main Features

     Low power consumption and long battery life Note: Battery life is determined by the sensor reporting frequency and other variables, please refer to http://www.netvox.com.tw/electric/electric_calc.html. On this website, users can find battery life time for varied models at different configurations.

  • Page 11: Application Scenario

    6. Application scenario In the use case of detecting the water level in water tanks, the device should be installed on the top of the water tank. After the device is installed and powered, turn on the device and it will detect the distance between the device and the water as well as the percentage of the water level in the water tank.

  • Page 12: Installation

    7. Installation Kindly note the illustration is only for reference. 1. The device can be installed in the middle or anywhere of the top of the container that is flat enough to ensure the ultrasonic detection direction will be vertical to the detected object, so the accuracy can be maintained. 2.
  • Page 13 4. If the top of the water tank can be opened, it is recommended to make a hole of diameter 32mm on the top of the water tank. 5. If the top of the water tank cannot be opened, the hole made on the top of the water tank is recommended to be 45mm diameter. It is recommended to add a gasket (size: 32.4*57.4*3mm) between the hole and the sensor.

    8. Keep the device from electromagnetic disturbances. 8. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.

  • Page 15: Important Maintenance Instruction

    9. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
