This product complies with the national standard of the People’s Republic of China, GB/T 778-2018, titled \"Meters for cold and hot drinking water.\" It measures the flow rate of the fluid by utilizing the difference in propagation time of ultrasonic waves in forward and reverse flow directions; flow volume is thus determined based on this flow rate. Thanks to its high accuracy and resistance to high flow rates, it enables accurate measurement of flow in pipelines located in outdoor areas or in places where electricity is unavailable. It can also operate stably even under high flow conditions for extended periods of time. Suitable for measuring water used in firefighting applications, this is an industrial-grade ultrasonic water meter that offers various output options. It allows the transmission of data collected on-site to a control room via wireless networks, thereby addressing the issues associated with traditional mechanical water meters, such as high starting flow rates, inability to measure low flow volumes, and difficulties in remote, real-time reading. It is widely used in heating systems, tap water supply, sewage treatment, industrial circulating water systems, cooling water and hot water systems, as well as in tap water distribution networks.

• It features a fully sealed design that makes it waterproof.
• Installation can be carried out while the water flow is ongoing, without the need to stop the water supply; this makes on-site installation fast and convenient.
• It uses environmentally friendly lithium batteries, allowing it to operate continuously for over 15 years (an external power supply can also be used as an option).
• It boasts high precision, strong signal quality, low power consumption, good stability, low starting flow rate, a wide measurement range, and is not affected by water quality.
• A temperature sensor is included to measure the temperature of the water flowing in and out of the heating/cooling pipes, enabling the calculation of heat/cooling capacity.
• There is no need to adhere to the usual installation requirements regarding the position of the flow meter; it can still provide accurate measurements even in extremely harsh pipeline conditions.
• An RS485 interface can be added to meet various user needs, facilitating remote data collection for easier centralized management. It can also alert users to any abnormalities in the pipeline system.
