Gas Pulse Sensors

APC Smartwave provides a range of gas pulse sensors capable of measuring consumption and flow by connecting to gas meters with pulse output. Our gas pulse sensors provide precise, real-time data that can help you compare actual consumption against billed consumption and form an complete picture of consumption highs and lows over time.

Indoor Pulse Sensor

Real-time indoor pulse sensors from APC Smartwave are battery powered wireless transmitters capable of capturing pulse information from 2 meter points.

The sensor monitors the number of pulses from the meter and can be used with any meter where a mechanical pulse output is available including gas, electric (including sub meters) and water meters.

Our indoor pulse sensors are available for dual and single input.

Adeunis Modbus

The Adeunis LoRaWAN Modbus Master is a ready-to-use radio transmitter with a Modbus interface. This product meets the needs of users to communicate with one or several Modbus slaves and transmit the information via a LoRaWAN, Sigfox or Wireless M-Bus network.

  • Can handle up to 10 slaves with 15 registers by slave
  • Transmits the data from the slaves either periodically or in an event-related way based on high or low thresholds
  • The configuration of the transmitter is accessible by the user via a micro-USB port or remotely via the LoRaWAN network, allowing in particular a choice of modes of transmission, periodicity or triggering thresholds
  • Powered by an external power supply (not included)
  • Can provide and control the power supply for a slave

Elsys ELT-1

ELT-1 and ELT-2-HP are general LoRaWAN devices for measuring analogue or digital signals. ELT-1/ELT-2-HP can be used together with electricity meters, flow meters, analogue sensors, moisture sensors, temperature sensors, water leak cable or ultrasonic distance sensors. They are enclosed in an IP65 box and are designed to be outside. Inside the ELT-1/ELT-2-HP you will find three internal sensors: a temperature sensor, a humidity sensor and an accelerometer for orientation measurements.
