The ultrasonic heat meter is composed of a flow sensor, a matching temperature sensor, and a calculator, featuring a compact structure and easy installation.
Our products utilize ceramic piezoelectric transducers, ensuring high accuracy and stability; with no mechanical movement, no wear, and resistance to poor water quality, as well as low maintenance costs; they can be installed horizontally or vertically, and can be mounted on either the inlet or return pipes according to the user's specific needs (preselection required); RS485 interfaces can be added to meet various remote meter reading 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 pipes. The outlet should be higher than the heat meter; when installed vertically, the flow direction must be upward.
4. Ensure that new piping is thoroughly cleaned of debris such as stones, sand, and fibers 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 on the heat meter's inlet, where D is the diameter of the heat meter pipe. The straight pipe section at the front end of the outlet should not be less than 5 times the diameter of the pipe. When installed at the junction of two return water lines, the straight pipe section of the heat meter connection head (such as a T-joint) should be 10 times the diameter of the pipe to ensure uniform mixing of the water temperatures in the two lines.
6. Data is collected from the heat meter via the M-Bus bus; do not connect this wire to the city power supply, otherwise it may damage the meter.
7. For the heat meter with a top row 485 interface, please note the polarity of the A and B wires when connecting.
