Heat-LoRa Metering Ultrasonic DN15 is an innovative heat meter with static flow sensor based on the ultrasonic measuring principle with LoRaWAN technology. The Heat-LoRa Metering is designed to measure heat usage where water is the hot/cold carrier medium. Heat-LoRa meters are devices designed to detect the thermal energy supplied by a source, measuring the temperature variation between the input and output of the system.Heat-LoRa Metering Ultrasonic also available in the DN20-25-32-40 version

LoRa-Water Metering Ultrasonic & Valve Control is an ultrasonic water meter with LoRaWAN technology. Provides an all-in-one smart water meter solution, offers measuring range ratio up to R400 (Q3/Q1). LoRa-Water Metering Ultrasonic & Valve Control is far better than the standard mechanical water meter. LoRa-Water Metering allows remote control of the valve to block the flow of water. The Ultrasonic Meter is designed for indoor installation in non-condensing environments with ambient temperatures from 5~55°C. The Valve Control meter has IP68 protection class which allows for long term submersion. Make sure that the meter is installed far enough away from possible sources of electromagnetic interference (switches, electric motors, fluorescent lamps, etc.).
