Our YG-RLM(S) series is a new generation of integrated single-flow heat meters, purpose-engineered for residential heating and cooling systems across Europe and Russia. Built on the proven performance of our flagship YG-RLM line, these meters integrate advanced nonmagnetic sensing technology to eliminate magnetic interference and deliver consistently reliable, error-free data collection. With a compact, lightweight design and industry-leading metering precision, our solution is purpose-built for heating contractors, utility providers, property management operators, and wholesale distributors seeking a compliant, low-maintenance, and cost-effective residential heat metering solution.
Traditional mechanical heat meters are prone to magnetic interference, which causes metering inaccuracies, billing disputes with end users, and costly on-site maintenance and remediation. Our advanced nonmagnetic measurement architecture eliminates this risk entirely, ensuring stable, long-term performance and uninterrupted, precise data capture. This design drastically reduces your after-sales workload, cuts operational costs, and preserves end-user satisfaction across every installation.
Every unit in the YG-RLM(S) series is manufactured to meet strict Class 2 metering requirements, fully compliant with EN1434 and CJ128 international regulations. This guaranteed compliance ensures your billing data meets the strictest global and regional benchmarks, eliminating regulatory risk for your projects in Europe, Russia, and other regulated markets. Our wide 100×1 measuring range and ultra-low start flow rate capture even the smallest energy consumption, preventing revenue loss from low-flow operating conditions.
Our heat meters support both horizontal and vertical installation, adapting seamlessly to nearly any residential pipeline layout without costly system modifications. We’ve integrated an embedded, removable installation design to protect the device during initial system commissioning and flushing, preventing physical damage and reducing installation-related failures. This flexibility cuts on-site installation time, lowers labor costs, and simplifies retrofits in existing residential heating systems.
To streamline operations for multi-unit residential complexes and district heating networks, our meters offer optional remote communication protocols including M-BUS, RS-485, and pulse output. These protocols enable seamless integration with smart building management systems and centralized remote meter reading platforms, eliminating the need for manual on-site inspections. For utility providers and property managers, this translates to an 80%+ reduction in routine operational costs and real-time visibility into system performance.

Our single-flow heat meters cover a nominal flow range of 0.6 to 2.5 m³/h, with a wide measuring ratio of 100×1 and an ultra-low starting flow rate. This high sensitivity ensures accurate capture of even minimal energy consumption, making the meters ideal for high-efficiency residential buildings where precise monitoring of small flow fluctuations is critical for accurate billing and revenue protection.
With a maximum working pressure of 1.6 MPa and an operating temperature range of 4℃ to 95℃, these meters deliver consistent Class 2 accuracy across the full range of standard domestic plumbing and heating system conditions. They perform reliably in both supply and return line installations, with a low pressure loss of just 24 kPa/Qp to minimize impact on system circulation efficiency.
Every meter is supplied with a matched pair of high-accuracy PT1000 temperature sensors, engineered to detect even the slightest variations in supply and return water temperature. The on-board calculator processes signals from both the flow sensor and temperature sensor pair to deliver highly accurate thermal energy calculations, eliminating errors from temperature differential misreading.
Beyond our core performance advantages, the YG-RLM(S) series includes a suite of user-centric features designed to reduce long-term operational costs and simplify maintenance for our commercial partners:
Extended Battery Life: A high-capacity lithium battery delivers a service life of over 6 years, reducing scheduled maintenance and battery replacement costs over the meter’s lifespan.
Long-Term Data Storage: On-board internal memory supports 18 months of historical consumption data storage, with renewable billing settlement dates to enable comprehensive historical trend analysis and dispute resolution.
