Working principle

The meter comprises the quality temperature sensor ,the flow sensor and the calculator. The temperature sensor to measure the temperature of water and the flow sensor to measure the volume of water that flow through the pipelines by the transit time difference.
The two data is sent to the calculator after being collected, the consumption water quantity is worked out, stored and indicated on the LCD finally.

Water meter

1. How long is the battery life?

Using the ER26500 battery with a capacity of up to 9000 mAh and the frequency of reading the meter once a day, the battery life can reach 8 years.

2. Waterproof rating?

At present, this water meter adopts completely encapsulated and sealed technology. It uses silicone to package the circuit board part, and the battery plug and socket are also sealed to achieve IP68 protection.

3. Can your product run underwater?

This product can be soaked in water, but soaking in water will affect the stability of signal transmission, because it will greatly affect the signal transmission in water

4. If the valve cannot be closed or opened, how to find and deal with it?

If the valve is blocked by sand and gravel flowing into the pipe, the program in the water meter will try to execute the on-off valve action within 40 seconds.

If the valve cannot be switched normally, the water meter will give up the command and return the fault data to the platform.

On the platform, you can easily view the relevant information of the water meter.

Communication and service platform

1. What data can the platform collect from the water meter?

Currently, our platform can collect cumulative flow, battery voltage, and upload time on the water meter.

2. How do you know that the water meter is faulty and there is no data to return?

First, we can check the alarm function on the platform to see if the water meter has no data returned, and then check the installation environment to see if there is any obvious damage, and can actively trigger the water meter to turn on-line mode 

3. Is the platform free? Can I pay in advance?

It is free, and the administrator can charge the amount in advance

Set user information files for each user on the platform
