Installation Requirements Note: For ultrasonic water meters that have been installed, under freezing conditions in winter, to prevent the pipes from being cracked by the ice and potentially damaging the ultrasonic sensors, it is crucial to at least open one valve (either the valve before the water meter or the water inlet valve/ faucet inside the user's room).
Page 14
Installation Requirements, Continued Horizontal Installation: For horizontal installation, it is suggested to arrange the pipes in a 'U' shape, as shown as shown in figure A. In this case, the ultrasonic water meter section at the lower position will maintain a full pipe. Figure A...
Page 15
Installation Requirements, Continued Vertical Installation: For vertical installation, as shown in figure B, the water flow should enter from the bottom and exit from the top at the meter. This arrangement prevents air bubbles from accumulating in the meter’s measuring pipe when water is flowing. Figure B...
Page 16
Installation Requirements, Continued Compromise installation (horizontal): When the recommended horizontal installation is challenging to implement due to on-site conditions, the installation should at least be carried out as shown in the figure C. Figure C In the figure, the pipe section before the water meter can be parallel to the body of the meter (unlike the recommended method, which eliminates the right-angle bends), but the pipe...
Page 17
Installation Requirements, Continued 1. Precautions Before Installation: (1) Thoroughly clean the pipes before installing the ultrasonic water meter to avoid debris damaging the meter. (2) Handle the relatively expensive and precise ultrasonic water meter carefully when lifting and placing it; do not directly pull the meter head or sensor wires;...
Page 18
Installation Requirements, Continued (6) It is recommended to have filters of corresponding sizes installed before the meter; valves of appropriate sizes should be fitted both before and after the meter, allowing separation from the meter body for future maintenance and repairs.
Page 19
Installation Requirements, Continued (2) When installing on a 'U'-shaped pipe, place the meter at the lowest point to prevent air from accumulating at higher sections of the pipe, causing inaccurate or no measurement (as shown in figure E). Figure E (3) When installing at a bent pipe, ensure a distance of ≥5 times the diameter for the straight pipe before and ≥3 times the diameter for the...

Installation Requirements, Continued (4) If installing a valve or other objects before the meter, ensure a distance of ≥5 times the diameter between the meter and the object to prevent inaccurate measurement (as shown in figure G)." ≥5D ≥3D <5D <3D Figure G...
Installation Install the FlowSmart All-in-One 1. Identify a suitable location in the piping that satisfies all installation requirements. 2. Assemble the supplied spuds/couplings on the meter: a. Insert a coupling through the nut. b. Place a gasket inside the nut (on top of the coupling flange).
Page 22
Installation, Continued 3. Loose-fit the female pipe fittings (not provided) onto the meter couplings. 4. Holding the meter against the pipe at the installation location, mark the overall length. 5. Cut the piping, using an appropriate pipe-cutting tool, per the tool manufacturer’s instructions.
Page 23
Installation, Continued 10. Insert the couplings onto the fittings. Hand-tighten. 11. Use pipe wrenches to tighten an additional half to one full turn. **Do not overtighten!** 12. With the dial facing up and with the arrow pointing in the flow direction, hand-tighten the coupling nuts to the meter.
Testing 1. To test the FlowSmart All-in-One, first press the SET button on the unit. Listen for a smooth, consistent sound, indicating the motorized valve is functioning properly. Ensure the valve is fully closed; you can verify this by checking that no water is flowing through it, as any water movement might produce a noticeable sound.
