Our DN15-DN40 ultrasonic heat meter is a cutting-edge smart metering solution designed specifically for residential HVAC and district heating systems. Built with industry-leading ultrasonic metering technology and ultra-low power consumption control architecture, this residential HVAC ultrasonic heat meter delivers real-time, high-precision data acquisition of flow rate, supply and return water temperature, and thermal energy consumption for clients in the heating and building management sectors. Equipped with multi-functional alarm systems and optional IoT communication modules, it empowers heating operators, property managers, and real estate developers to achieve scientific, data-driven dynamic management of heating usage, drastically improving operational efficiency, reducing energy waste, and elevating end-user service quality. As a Class 2 ultrasonic heat meter, it fully complies with international metering standards, making it a reliable choice for large-scale residential heating projects and commercial HVAC retrofits.
Adopting high-sensitivity PT1000 temperature sensor ultrasonic heat meter technology, it achieves 0.01℃ temperature resolution, paired with 0.01m³ flow resolution and 1kWh heat resolution for unrivaled metering accuracy. This heating and cooling dual-purpose ultrasonic heat meter supports bidirectional metering of both heating and cooling energy consumption, with an 8-digit LCD display showing cumulative energy, thermal power, inlet/return water temperature, temperature difference, flow data, and alarm records for full visibility of system performance.
Engineered with an optimized ultra-low power consumption circuit design, this 10-year lifespan ultrasonic heat meter is powered by a DC 3.6V lithium battery, delivering a continuous service life of over 10 years without frequent battery replacement, drastically reducing long-term maintenance costs for project operators. It also features built-in low battery alarm and sensor abnormality alarm functions, ensuring uninterrupted, reliable operation throughout its service life.
This horizontal vertical mounting ultrasonic heat meter supports both horizontal and vertical installation, with a multi-angle adjustable display for easy reading in complex installation spaces. With a IP68 waterproof ultrasonic heat meter protection rating, it is fully dust-tight and submersible, making it suitable for harsh installation environments including basements, pipe wells, and high-humidity mechanical rooms, with a maximum working pressure of 1.6MPa to adapt to various HVAC system pressures.
The meter offers flexible communication options including M-Bus, NB-IoT, and 4G, making it a highly versatile NB-IoT ultrasonic heat meter for smart heating systems. It enables automatic data upload to a cloud-based operation management platform, supporting remote meter reading, fault monitoring, and energy consumption analysis, eliminating the need for manual on-site meter reading and enabling efficient centralized management for heating utilities and property management companies.
