Float level sensor ARF817 series

for liquidsliquidLoRaWAN

Overview
The Double-level-sensor is a ready-to-use product enabling the detection of a double level of liquid. The package is composed of a DRY CONTACTS transceiver and a double-level sensor. Default settings have been established to simplify product installation by the user.

Highlights of the IoT sensor

• 4 configurable inputs/outputs:
  • Control an output based on change in the state of an input
  • Remote and near-real-time control of output – LoRaWAN Class C
  • Track the time spent in a given state
• Over 15 years of autonomy (depending on version and configuration)
• Local and remote configuration
• Data transmission modes: periodic and/or event-triggered
• Compatible with KARE
• Available versions: LoRaWAN: EU863-870 / US902-928 / AU915-928 / AS923-1; Sigfox: RC1 / RC2 / RC4

What actions are carried out by the connected sensor?

• Alert: Alert on events – warn when the level rises or drops, anticipate an overflow, prevent the end of the tank.
• Monitor: Count the number of status changes, evaluate the time spent in a given state.

Features of the Double Level Sensor

• Four configurable digital inputs/outputs
• LoRaWAN Class C (with external power supply)
