Powermax ultrasonic water meter is designed to survive against harsh environments, solids in water, magnetic vandalization, and other issues standard water meters cannot withstand. Primarily for residential use, its applications include revenue metering, AMR, and residential submetering with leakage detection. Utilizing a smart water meter is crucial for efficient water flow, saving on bills, and prompt leak repairs. Early leak detection can prevent property damage, making real-time leak alarms vital for managers and homeowners. Water filtration systems are equally important for treated water, but they can disrupt flow unintentionally.
Support Modbus wired, 4G, Pulse Output, RS485 Communication. Compatible with GB/T 26831, CJ/T 188, and Modbus RTU communication protocols.

Notices for Installation
1. Flush pipes before installation to avoid gravel and other foreign objects;
2. Install a valve and filter before the water meter;
3. Do not touch the electrical part or pull wires to avoid damage during installation;
4. Reserve an adequate space for maintenance during installation;
5. When the water meter is installed in a horizontal or inclined way, the ultrasonic flow probe on pipes shall be placed horizontally, and when installed vertically, make sure the water flows from down to up.
6. Please note that the arrow direction on the pipe shall be consistent with the water flow direction during installation;
7. The joint washer shall be installed correctly to avoid misaligned washer blocking water and affecting the accuracy of the water meter;
8. The water meter shall not be installed at a place that may be affected by strong mechanical vibrations;
9. Installation Figure:
Special Notices:
- Be sure to install an on-off valve and filter before the water meter and another on-off valve is recommended after it for maintenance;
- If the ultrasonic water meter is installed through the flange, make sure the parallelism between the water meter flange and the pipe flange is not more than 0.5% of flange outer diameter and is less than 2mm, otherwise, it may result in damage to the the water meter.
10.Ensure a 5 times and a 3 times of straight-pipe run before and after the water meter, respectively, during installation;
11.The water meter shall refresh the display at every 8 seconds, and read the water meter (including the starting value and end value) 8 seconds at least after the valve is closed when test the water meter, otherwise the testing results may be affected;
12.Please make sure the medium flow is within the flow range of the water meter during test and use, otherwise it may result in damage to the water meter;
13.In case of any malfunction (e.g. metering failed, etc.) during use, please contact the related management department immediately and do not repair it by yourself;
14.The product is designed with a disposable anti-disassembly seal which shall be removed only by appointed personnel, or otherwise it shall be excluded from the free after-sales service.
