Ultrasonic heat meter with LoRaWAN communication
The Sharky 775 2,5m3 190mm DN20 TempSensor Ø5,2mm LoRaWAN is a Diehl Metering ultrasonic compact energy meter designed for heat and thermal energy measurement in residential, commercial and district heating installations. This configuration has a nominal flow rate of 2.5 m³/h, DN20 nominal diameter and an overall installation length of 190 mm.
The SHARKY 775 uses ultrasonic flow measurement without moving mechanical measuring parts. LoRaWAN communication enables remote meter reading through a compatible LoRaWAN gateway, network server and receiving energy-management or billing platform.
2.5 m³/h DN20 thermal energy measurement
This SHARKY 775 configuration combines a qp 2.5 m³/h flow sensor with DN20 nominal diameter and 190 mm overall length. Diehl specifies a G1B meter connection for this version, with an R¾ coupling connection when matching couplings are used.
The meter calculates thermal energy from ultrasonic flow measurement together with supply and return temperature measurements. This configuration is specified with Ø5.2 mm temperature sensors and LoRaWAN communication for remote data collection.
See the official Diehl Metering SHARKY 775 product information and documentation for detailed specifications, installation requirements and communication options.
