1. In order to ensure the most accurate measurement, install a straight pipe section with at least 5 times the surface diameter of the pipeline and the same section in front of the water meter inlet, and install at least 2 times the straight pipe section of the water meter outlet at least.

2. The connecting pipes at the upstream and downstream of the water meter cannot be reduced in diameter;

3. It is recommended to install flow control equipment (such as valves) and filter equipment;

4. The flange sealing ring must not protrude into the pipe or be misaligned;

5, must be thoroughly cleaned before installing the water meter to avoid damage to the water meter debris;

6. The flow direction of the water meter should be the same as the flow direction of the pipeline;

7. After the water meter is installed, slowly discharge water to fill the pipeline to prevent the high-speed air flow from crashing the meter.

8, the installation location should ensure that the pipeline is full of water, air bubbles will not be concentrated in the table, should avoid the water meter installed in the highest point of the pipeline;

9. Water meters should be protected from water pressure shocks;

10. Small-caliber rotor-type water meters must be installed horizontally. Tilting forward and backward or left and right will result in reduced sensitivity.

Intelligent water meter common fault causes and troubleshooting methods:

Fault phenomenon

cause

Method of exclusion

The clamping mechanism moves too slowly or the clamping force is too low

1. Water pressure is too low.

2. Two-position four-way clamp switch seal leak

is too big.

3. Leakage of the seal in the clamping mechanism.

1. Water pressure must be 2.5-4MPa. 2. Replace the two-position four-way clamp switch seal (usually two "O" rings on the valve stem).

3. Replace the seal again.

Gauge drain valve leak

1. Drain valve cone rubber cover variant or foreign body.

2. The drain valve seal wears.

3. Two-position four-way drain switch seal

Worn circle.

1. Replace the tapered rubber cover or remove foreign objects.

2. Replace the seal of the drain valve.

3. Replace the two-position four-way drain switch seal (usually two "O" rings on the valve stem).

Solenoid valve does not move

1. Solenoid valve power cable connector loosen

2. Solenoid valve coil open circuit

1. Check the power cord reconnect

2. Replace solenoid valve coil

Can't beat

1, hydraulic pump seal leakage

2, pipeline leakage

3. There is air in the tube

1, replace the seal ring

2, replace the seal ring

3, pressure booster handle turn left and right several times
