Adopts non-contact ultrasonic metering technology with no mechanical rotating parts, avoiding metering accuracy degradation caused by wear and tear, and greatly prolonging service life; equipped with a 10-year long-life lithium-thionyl chloride battery, eliminating the need for frequent power replacement; the backlit LCD can display real-time current water consumption, heat consumption, cumulative usage and indoor temperature data, supporting manual wake-up and automatic sleep mode; meets EU MID certification standards with metering accuracy up to standard, and can be directly connected to municipal charging systems, solving the pain points of traditional metering equipment that requires manual meter reading and inaccurate data.

The overall dimensions are 180mm × 80mm × 60mm, and the overall weight is 1.2kg; the water inlet and outlet calibers are DN20 (3/4 inch); the flow measurement range covers 0.01~10 m³/h, and the heat measurement range covers 0.01~10 MW; the working environment humidity is 30%~90%RH without condensation; it adopts IP65 waterproof rating, adapting to indoor and outdoor installation; the power supply is 3.6V ER14505 lithium-thionyl chloride battery, with standby power consumption ≤0.5μW; supports static data storage for more than 10 years.

It is mainly suitable for water and heating metering scenarios in family residences, studio apartments and small homestays, replacing traditional rotor-type water meters and heat meters, providing a pre-base for remote meter reading for landlords and property managers, and also allowing individual users to control household water and heat costs in real time, adapting to civil water and heating installation standards in the EU and North America.
