Lanry LHM ultrasonic heat meter is divided into small-bore household type (DN15~DN40) and large-caliber industrial type (DN50~DN400), adopting static ultrasonic measurement without moving internal components. It supports both heat and cold metering, with Class 2 measurement accuracy, and built-in lithium battery that can run continuously for 7 to 10 years relying on ultra-low power consumption design. The product integrates multiple communication methods including M-Bus, and optional RS485 Modbus and NB-IoT wireless remote transmission, which can meet diversified heat measurement demands from household end users to municipal heating main pipes.
Unique Strengths Supporting Multi-scene Deployment
- Wear-free long-term operation: No mechanical rotating parts, pressure loss controlled below 25kPa, no frequent maintenance required.
- All-round self-diagnosis protection: Automatic alarms for flow sensor failure, temperature sensor open/short circuit, over-range and low battery to avoid abnormal billing.
- Dual heating & cooling measurement: 25°C automatic switching threshold, compatible with heating supply and central air-conditioning cooling systems.
- Flexible data reading mode: Local infrared handheld meter reading, plus wired/wireless remote data upload for centralized heat management.
- Complete caliber specifications: Thread connection for small household pipelines, flange connection for large main pipes, with optional R100 high turndown ratio for industrial working conditions.
Target Application Fields
1. Residential Community Household Heat Metering
The DN15-DN40 small-bore heat meter is installed on the independent heating pipeline of each household. Long-life built-in battery avoids frequent power replacement, and M-Bus remote transmission helps heating enterprises realize automatic heat consumption collection, supporting accurate and fair heat fee settlement for residents.
2. Commercial Public Building Central Air Conditioning
Suitable for office buildings, shopping malls, hotels and schools. It can measure heating consumption in winter and cold consumption in summer at the same time. NB-IoT wireless upload function connects to the building heat management platform to realize real-time statistics of air conditioning heat consumption.
3. Municipal Heating Station & Heating Network Main Pipe
Flange-type DN50-DN400 large-caliber heat meters are used for heat exchange stations and municipal heating trunk pipelines. Stable long-term cumulative heat measurement provides reliable data basis for heat supply network operation scheduling and heat balance auditing.
4. Factory Circulating Water & Constant Temperature Process Pipeline
Applied to industrial workshop cooling circulation pipelines and production constant temperature systems. With 1.6MPa nominal pressure resistance and intelligent data error correction technology, it ensures stable and accurate heat measurement, convenient for enterprises to carry out energy-saving transformation and heat consumption statistics.
Overall Application Value
Compared with mechanical heat meters prone to wear and stuck failure, LHM ultrasonic heat meter has outstanding advantages of low maintenance cost and long service life. The dual cold and heat measurement function and multi-channel remote communication design make it a universal heat measurement solution covering residential, commercial, municipal and industrial scenarios.
