1、 Purpose and scope:
Used to measure and control the total volume of water flowing through the tap water pipeline. This table has the characteristics of high stability and low power consumption.

2、 Functional features:
1. Using wireless remote transmission, with no exposed electrodes, easy to use, and can be customized to IP68 or split according to customer needs.
2. Volumetric water meter, sends signals by volume.
3. Stainless steel casing, positive displacement movement.
4. Long distance wireless transmission, open distance up to 2 kilometers, single meter can pass through 3 buildings.
5. When the battery voltage is too low or there is a power outage, the valve will automatically close and the management department will be notified remotely.
6. Card free prepaid, remote switch valve, remote meter reading
7. Low initial flow rate and high accuracy.
8. Display function (optional): Parameters such as the amount of water purchased, remaining water, and cumulative water consumption can be displayed on the LCD screen. Users can view the remaining water and cumulative water consumption information in the table through their user card.

3、 Technical parameter description:
1. Technical indicators:
Operating temperature: 0 ℃ -40 ℃ (cold water) 0 ℃ -90 ℃ (hot water) Operating humidity: ≤ 95% Operating voltage: 3.0V-3.6V
Static working current: ≤ 3μA

2. Traffic indicators:

4、 Instructions for use:
User account opening: Users need to pay at the management department. For users who owe fees, the management department can remotely turn off the electric valve.

5、 Installation:
1. The selection of a water meter should be based on the fact that the flow rate of the pipeline that is frequently used is less than or close to the commonly used flow rate of the water meter, and cannot be determined solely by the diameter of the pipeline.
2. The installation location should avoid strong sunlight, freezing, and pollution. During periods of freezing, in addition to wrapping and insulating the water pipes of the water meter, the inlet valve of the water meter should be closed and the outlet valve and faucet should be opened when not in use to avoid freezing and damage to the water meter.
3. The water meter must be installed horizontally with the face up.
4. When installing pipelines, it is necessary to wash away stones, mud, hemp fibers, and other debris inside the pipes before installing water meters to avoid water meter malfunctions.
5. For accurate measurement, the faucet should be higher than the water meter.
The water meter should not be directly connected to the pipeline. There should be movable interfaces between the water meter and the pipeline (such as pipe joints, connecting screws, connecting gaskets, etc.). When installing a water meter, excessive force caused by pipes and fittings should not be applied to avoid damaging the water meter.
