Product Description
Production standard: National Standard of the People's Republic of China GB/T778.1~778.5-2018 "
Important hint:
(1). Please read the user manual carefully before use, and keep the user manual properly for reference;
(2). This product is a precision measuring instrument. During installation and use, keep away from interference sources as far as possible, choose a reasonable installation location, and avoid severe impacts and collisions;
(3). This product has undergone strict quality inspection before leaving the factory, non-standard operation or unauthorized disassembly is strictly prohibited, otherwise the consequences will be at your own risk;
(4). The displayed patterns and prompts are window operation prompts and cannot be used as the basis for product verification;
(5). For product verification, please choose a regular flow verification device that meets the national measurement requirements, and operate in strict accordance with the specifications;
(6). Since the water meter will be upgraded from time to time, if the actual function of the product is inconsistent with this manual, please refer to the actual product or consult the manufacturer;
(7). When an error message appears, please contact the manufacturer or dealer in time, otherwise it will cause traffic loss.
This product does not support reverse flow measurement, please be informed!

5,Installation Notes:
(1). The diameter of the water meter should be selected according to the diameter of the pipeline at the installation site and the flow rate should be less than or equal to the usual flow rate;
(2). The installation location should be selected where it is easy to disassemble and read the power data of the water meter;
(3). During installation, sand, gravel, tape, iron wire and other sundries should be prevented from entering the water meter pipeline, which may cause water meter measurement failure;
(4). When installing, the direction of water flow should be consistent with the direction of the water meter arrow;
(5). The water meter is not suitable for measuring hot water, please do not install it in hot water places such as solar energy and bathing;
(6). After installation, please switch to the signal display interface and read the signal value. The signal value should be more than one grid.
6,Window Operation
The water meter is usually in a low-power off-screen state, and it can be woken up when the magnet is placed in the lower left corner of the screen (where the CPA logo is located). The magnet moves across the lower left corner of the screen to realize switching and cycling of the display window.
Main components and parameters
- It is specially used for accurate metering of small-diameter water in residential areas or other places;
- Ultrasonic measurement, effectively avoiding the interference of traditional magnets;
- The minimum measurable flow velocity is only 0.005m/s (DN15), truly realizing drip metering;
- LCD display, complete prompt function, convenient for inquiry and diagnosis;
- Small size and low power consumption design, the actual service life is more than 8 years;
- Excellent linearity, consistent linearity within the full scale range, no need for multi-point calibration;
- Perfect software expansion function, which can meet the customization requirements of different users;
- A variety of measurement units are available to meet the needs of users in different countries;
