The Ultrasonic Heat Meter is composed of a flow sensor, a paired temperature sensor, and a calculator, featuring a compact structure and easy installation.
Our products utilize ceramic piezoelectric transducers, ensuring high accuracy and stability; they have no mechanical movement, no wear, are not easily affected by poor water quality, and have low maintenance costs; they can be installed horizontally or vertically, and can be mounted on the inlet or return water pipes according to the user's specific needs (preselection required); RS485 interfaces can be added upon customer request to enable remote meter reading functions to meet various requirements, facilitating centralized management.

The heat meter must be installed in a dry, easily accessible location.
2. Install the heat meter using professional installation tools.
3. The heat meter must be installed according to the installation method indicated on the label (horizontal/vertical), with the face up, and the arrow direction on the meter body (including the filter) aligned with the flow direction of the HVAC pipeline. The outlet should be higher than the heat meter; when installed vertically, the flow direction must be upwards.
4. Ensure that new piping is thoroughly cleaned of debris like stones, sand, and string before installing the heat meter to prevent malfunctions; according to the individual heating metering design requirements for heating systems, a filter must be installed before the heat meter's inlet; the filter must be cleaned and maintained regularly.
5. To achieve measurement accuracy, leave a straight pipe section of approximately 10D length at the inlet of the heat meter, where D refers to the heat meter's pipe diameter. The straight pipe section at the front of the outlet should not be less than 5 times the diameter of the pipe. When installed at the confluence of two return water pipelines, the heat meter connection head (e.g., T-joint) requires a straight pipe section 10 times the diameter to ensure uniform mixing of water temperatures between the two pipelines.
6. Data is collected from the heat meter via the M-Bus bus. Do not connect this line to the city power, otherwise it may cause damage to the meter.
7. For the heat meter with a 485 interface at the top, please note the polarity of A and B lines when wiring.
