Technical characteristics and parameters
The YGM ultrasonic thermal energy meter consists of a flow sensor, a paired temperature sensor, and a calculator, and has the characteristics of compact structure and easy installation (hereinafter referred to as the thermal energy meter). This product uses high-quality piezoelectric ceramic transducers to ensure high accuracy and stability; No mechanical movement, no wear and tear, not easily affected by poor water quality, and low maintenance costs; The head can be installed horizontally or vertically, and the rotatable head can meet the reading requirements of any viewing angle. During installation, it can be installed on the inlet or return pipeline according to different user needs (pre selected); The dual-purpose (heating and cooling) heat meter can intelligently determine the heating or cooling status based on actual usage and measure them separately. M-BUS and RS485 interfaces can be added according to different user needs to achieve remote automatic meter reading function for centralized management.
Execution standard: Industry standard for urban construction in the People's Republic of China《Heat meter》(CJ128-2007)

Installation, use and precautions
The applicable model of the heat meter is determined based on the system flow rate rather than the system pipe diameter, and the diameter and model of the heat meter should be determined according to the commonly used flow rate.
According to the design requirements for household metering of heating, a filter must be installed before the inlet of the heat meter; The filter must be cleaned regularly.
3. The heat meter must be installed horizontally or vertically, and the direction of the heat meter identification arrow (including the filter) must be consistent with the direction of the HVAC pipeline water flow; Do not use return water pipes for water supply to prevent backflow and prevent impurities in the water from damaging the heat meter; When installed vertically, the direction of water flow must be upward.
Before installing the heat meter, the pipeline must be cleaned;
5. The hot water ball valve at the inlet of the heat meter is only allowed to be in two states: fully open and fully closed. The hot water ball valve at the outlet of the heat meter can adjust the flow rate.
6. The heat meter calculator (monitor) must not be soaked in water.
7. The quality of heating water should comply with relevant regulations.
8. A heat meter is a measuring instrument that must be regularly calibrated according to national standards, and the battery must be replaced during calibration.
9. To achieve insulation and avoid human damage to the measuring system, a heat meter box can be installed. If installed outdoors or in stairwells, it is forbidden to completely close the pipeline valve to avoid freezing the heat meter due to the lack of hot water flow.
10. Without the permission of our company, no one is allowed to disassemble or repair the heat meter without authorization, otherwise the warranty service will be automatically terminated.
11. Optional RS485 interface function, wiring meaning: red (+5V), white/yellow (B), green/blue (A), black (ground).
12. Some product specifications may change without prior notice.
