Ultrasonic energy meter, air conditioning cold and hot water meterSoftware upgrade can be achieved through the transmitted code files

*Protection level: IP68: This series of instruments adopts advanced low-power digital design technologies such as digital transmission, digital reception, digital analysis, and digital output. The instruments have accurate measurement, reliable operation, and are more suitable for the needs of industrial sites.

Five technical features of ultrasonic heat and cold meters specifically designed for central air conditioning:

① Ceramic sensors, metal alloy adhesives. High strength, wear-resistant, corrosion-resistant, and not prone to scaling. Especially suitable for measuring high temperature and highly corrosive liquids. By using metal adhesive, the bonding is more firm, and the operating temperature can reach 160 ℃, making it particularly suitable for acoustic sensors and greatly enhancing their engineering practicality.

② Micro power consumption and digital design. The whole machine adopts low-power hardware and software design to digitally transmit, receive, and analyze ultrasonic signals, achieving comprehensive digital design. The power consumption of the whole machine is less than 0.3W. The battery powered whole machine has a power consumption of only 0.2mW
