Product Q&A

Q:1. What happens to our billing data if the building suffers a sudden power outage?

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.

Q:2. Does the product come with official calibration certificates required by local authorities?

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.

Q:3. Is it difficult for our technical team to read the parameters manually on-site?

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.

Q:4. Do we need to replace the battery frequently? How high are the maintenance costs?

Maintenance costs are exceptionally low. The built-in 3.6 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.
