Ultrasonic heat meter with LoRaWAN communication
The SensoStar 2,5m3 130mm DN20 TempSensor Ø5mm LoRaWAN is an Engelmann ultrasonic thermal energy meter designed for heat and cooling energy measurement in residential, commercial and building energy applications. This configuration has a nominal flow rate of 2.5 m³/h, DN20 nominal diameter and a compact 130 mm installation length.
The meter can transmit measurement data through LoRaWAN to a compatible LoRaWAN gateway, network server and energy-management or billing platform.
2.5 m³/h DN20 thermal energy measurement
This SensoStar U configuration combines a qp 2.5 m³/h flow sensor with a DN20 connection, G1B thread and 130 mm overall length. The ultrasonic measuring principle enables thermal energy measurement without moving mechanical measuring parts in the flow sensor.
The meter uses Pt1000 temperature sensors and supports Ø5 mm probes. Thermal energy is calculated from measured flow together with the temperature difference between the supply and return circuits.
LoRaWAN is available as a wireless communication option for the SensoStar U platform. The meter also provides an optical interface, LCD display and storage of historical measurement values.
See the official Engelmann SensoStar U datasheet for detailed specifications, communication options and installation requirements.
