Our ultrasonic heat meter (Model: YG-RLM(C)-50-200) is an advanced intelligent energy measurement solution designed for heating and cooling system management, tailored for business clients including district heating operators, commercial facility managers, and HVAC system integrators. Developed and produced by a leading Chinese high-tech manufacturer with a 42,600 square meter production center and 1.5 million annual meter output, this heating system energy meter accurately calculates released or absorbed heat by measuring water flow volume and temperature difference between the supply and return lines of a heating system. Supporting both M-BUS and RS-485 communication protocols, the meter complies with EN 1434 metrological class B and CJ128 standards, making it a trusted choice for heating energy management projects across over 20 countries and regions worldwide. With a diameter range of DN50 to DN200, it delivers stable, high-precision measurement for both small commercial and large-scale industrial heating systems.
Unlike traditional mechanical heat meters, this class B ultrasonic heat meter adopts a non-intrusive ultrasonic measuring principle with no moving parts inside the flow channel. This design eliminates mechanical abrasion, ensuring long-term measurement stability and accuracy without performance degradation over extended service time. The meter achieves a wide flow range ratio of 50:1, with an ultra-low starting flow rate, enabling accurate measurement even in minimal flow conditions. It meets class 2 measurement accuracy standards, with a minimum measurable temperature difference of 3℃, adapting to variable heating load conditions in commercial and industrial systems.
This M-BUS RS-485 heat meter supports both horizontal and vertical installation in running pipes, greatly reducing the space requirements and installation difficulty for project contractors. It can be mounted on either the return or forward flow line, with the ability to calculate both heat and cold energy, making it suitable for both heating and cooling systems. The meter is equipped with a high-precision Pt1000 temperature sensor pair that complies with DIN EN60751 standards, ensuring stable temperature difference measurement in harsh working environments. It has a maximum working pressure of 1.6Mpa and a wide operating temperature range of 4-95℃, adapting to almost all district heating and commercial HVAC system requirements.
Engineered for modern smart energy management, this intelligent ultrasonic heat meter supports M-BUS and RS-485 remote communication protocols, enabling real-time energy consumption data transmission, remote meter reading, and energy use analysis for business clients. The meter features a 10-year long-life lithium battery, reducing maintenance costs and downtime for facility management teams. Its electronic components are fully detachable from the flow sensor, simplifying on-site maintenance and meter reading. The device is immune to external magnetic field interference, ensuring stable and reliable operation even in complex industrial environments, with built-in data recording functions for energy consumption and flow volume tracking.
