Page 5: Feature
Ultrasonic water meter is a new type of water meter which can measure and display the flow rate according to the time difference between upstream and downstream when the ultrasonic wave propagates in the water. Water meter can be equipped with wired or wireless data communication interface to communicate with the collector, concentrator or network server to form a remote meter reading management system. -

5. Infrared Meter Reading 6. Users can be equipped with a hand-held meter reading machine to record the accumulated flow, running time and other information of the water meter. The meter reading method can refer to the operation instructions of the handheld machine. 7. - Page 13 For horizontal installation, it is recommended to install as above and make the pipe line into "U". In vertical installation, as shown in the figure above, the water flow direction is inflow at the water meter at the lower end and outflow at the upper end. In this case, when water flows through, bubbles can be avoided to gather in the meter measuring pipe.

Page 14: Precautions Before Installation
Compromised installation (horizontal) If it is difficult to implement the recommended horizontal installation conditions due to the objective conditions on site, at least install as shown below. In the figure, the pipe section in front of the water meter can be parallel to the water meter body (the right-angle bending structure is eliminated compared to the recommended method), but the pipe at the back of the water meter must be arranged as shown in the figure, so as to avoid bubbles forming in the pipe. -

(4) The connecting pipes upstream and downstream of the ultrasonic water meter should be consistent with the diameter of the water meter and should not be reduced; (5) The direction indicated by the arrow on the surface body of the ultrasonic water meter is the direction of water flow, and reverse installation is not allowed. -
Page 16: Wire Connection
(3) When the meter is installed at the elbow, it must be ensured that the distance between the front straight pipe ≥5 times the pipe diameter and the rear straight pipe ≥ 3 times the pipe diameter, otherwise the meter may be inaccurate (as shown in Figure E). >5D (4) When the valve or other objects are installed in front of the meter, the distance between the meter and this object must be ≥5 diameters, otherwise the meter may be inaccurate;... -
