This meter adopts the time-difference ultrasonic measurement principle, calculating flow and heat by detecting the propagation time difference of ultrasonic waves in the fluid. It has no mechanical wearing parts, so no daily lubrication or maintenance is required, and its metering accuracy conforms to the ISO 4064 Class 2 standard. It uses food-grade plastic shell and brass movement, compatible with drinking water and heating circulation water media, avoiding water quality pollution problems. It is powered by 2 AA alkaline batteries with a service life of up to 2 years, eliminating frequent battery replacement needs. The LCD digital display is clear and easy to read, supporting USB data export in CSV format, solving the tedious process of on-site meter reading required by traditional mechanical water meters. Its compact size allows installation in small pipe wells without occupying too much space.
Four optional nominal calibers: DN15, DN20, DN25, DN32mm. The maximum working pressure is 1.0MPa, with an applicable medium temperature range of 2℃ to 90℃. The shell uses food-grade PP plastic paired with a brass valve core assembly. The total unit weight is approximately 0.8kg, with overall dimensions of 150mm × 70mm × 100mm. The metering resolution is 0.01 MWh, powered by 2 AA alkaline batteries with a service life of ≥2 years. It has an IP68 protection rating and no mechanical transmission structure. The installation method is snap-on threaded connection, compatible with household PPR pipelines. The USB interface supports CSV format data export, which can be directly uploaded to management software.
It is suitable for individual household heat metering in multi-story residential apartments and small commercial stores. It can be used as a replacement for traditional mechanical water meters in old residential community heating metering renovation projects, improving metering accuracy and management efficiency. It can also be used as a temporary metering device for small homestays and rental houses, facilitating landlords to count tenants' heat consumption. It complies with relevant national policies for urban heating metering, and can be matched with simple management software to organize and analyze energy consumption data.
