Ultrasonic Heat Meter with Remote Data Transmission Function

Your data is completely safe. The meter runs on a standalone internal battery, meaning it continues to measure and log data even during a total building blackout. Furthermore, its internal memory automatically saves all historical billing parameters, which can be safely recovered after any system fault resolution.

Yes. The HHU series fully complies with official legal metrology regulations (such as the JJG 225-2024 Heat Meter Calibration Regulations). Every unit is strictly calibrated before leaving the factory, making it eligible for official seal approval and energy auditing compliance in your local market.

Not at all. Thanks to its split-design construction, the electronic display can be rotated in any of four orientations to face the technician. The screen displays clear data, and the device features an easy-to-use button/magnetic sensor interface for quick on-site manual reading.

Maintenance costs are exceptionally low. The built-in $3.6\text{V}$ lithium battery has a long service life of 6+ years. Because it uses ultrasonic technology with no moving components inside the pipe, there is no mechanical wear and tear, resulting in almost zero routine maintenance costs.

The standard model is optimized for water and homogeneous liquids. If your central air conditioning (chiller) system uses a specific concentration of glycol or chemical additives, please inform our sales team before purchasing so we can calibrate the ultrasonic transit-time formula at the factory to match your exact fluid density.
