When not using water, the water meter rotates on its own

Reason for malfunction:

1. Excessive pressure fluctuations in the pipeline network;

2. The distance between the water meter and the main pipeline is too close;

3. Centralized installation of water meters, water hammer effect when adjacent users use water;

4. There is leakage and dripping in the pipeline network behind the table;

5. The water-saving meter is not equipped with a dedicated check valve or the check valve is stuck and cannot be reset;

6. There are blind pipes forming air columns in the pipeline network behind the table.

terms of settlement:

1. Self rotation is a common regional phenomenon, which may be due to excessive fluctuations in local water pressure. It is recommended to install an elastic check valve or replace the water meter with a less sensitive one;

2. If self rotation is an isolated or rare phenomenon, the self rotation of the water meter should be checked; If it is a continuous and uniform rotation, it is generally due to leakage in the pipeline network behind the meter; If it is intermittent rotation, check whether the installation position of the water meter is too close to the main pipeline or centrally installed, and whether there is an air column formed by the pipe network behind the meter;

3. If the water-saving meter installed with a check valve has self rotation phenomenon, the air in the pipe network behind the meter should be drained and the debris inside the check valve should be removed. If the water meter still rotates uniformly after treatment, it indicates that there is leakage in the pipe network behind the meter. If the user is inconvenient to repair, it is recommended to close the main valve before or after the meter when not using water.

The surface of the dial turns black

Reason for malfunction:

1. Poor water quality and sedimentation of dirt;

2. The water contains chemicals that react with ink;

3. The ink itself has quality issues.

terms of settlement:

1. Install a filter screen in front of the water meter pipeline,

2. Clean the surface and recalibrate or replace the watch with a new one.

Poor sensitivity or water meter not working

Reason for malfunction:

1. The debris in the pipeline is stuck and stuck;

2. Top looseness or overloading of water meters, excessive wear and tear;

3. The gear in the counter is stuck;

4. The water meter is working under overload, and the moving components are damaged and cannot be transmitted.

terms of settlement:

1. Install filter screen;

2. Simply remove the core and tighten the top. The water meter is strictly prohibited from working under overload;

3. Check whether the gear is broken, whether there are burrs or missing teeth on the gear;

4. Dismantle the watch, clean and replace damaged parts or replace the watch.

The character wheel does not carry forward

Reason for malfunction:

1. Gear and pot rod break and disengage;

2. The small gear of the wheel drive is stuck.

terms of settlement:

Replace the counter or a new meter.

The pointer falls off

Reason for malfunction:

1. The pointer does not fit tightly with the gear shaft, causing vibration and detachment;

2. There is no water on the surface, and there is a water hammer effect in the pipeline network, causing the pointer to detach;

3. The pointer is not installed properly.

terms of settlement:

1. Disassemble the water meter, reinstall the pointer, calibrate or replace the meter,

2. Open the water meter and fill the glass with water.
