Points to note when installing water meter

Points to note when installing water meter is the basic guideline for the construction work put to use to avoid the case of incorrect installation, affecting both the water user and the water side simultaneously. The water meter supply is also involved to explain the instructions again.

1. Ensure sufficient space to facilitate repairs and maintenance.

2. Install the accessories before installing the meter.

3. Measure accurately only when the input of the meter is 10 times (minimum 5 times) and the output diameter is 5 times (at least 3 times) the diameter of the meter.

(If there are valves, elbows, pumps, etc. on the front of the meter, it should be maintained more straight than the pipe.)

Valves and pressure reducers must be installed at the back of the meter as possible.

5. When installing the water meter, be careful not to allow sand or foreign substances, and ensure that it is installed horizontally.

Make sure the flow direction of the fluid matches the direction of the arrow on the body.

7. Install water meter so it does not freeze and freeze in winter.

Water meters are a precision instrument, so do not shake violently or externally.

9. When transporting and transporting, be sure to carry the box and do not damage the seal (sealed) that has been inspected by the national competent inspection agency.

Make a choice

Water meters have different operating ranges depending on the model and there is a partially unmovable zero flow area that can not be 100% accurate depending on the flow rate. In addition, when the meter exceeds the allowable capacity, the water meter rapidly decreases life expectancy and becomes abnormal. For this reason, it is necessary to consider the overall pressure of the water supply and drainage of the reservoir, the pump, the number of water supply equipment, etc., and calculate the minimum and maximum flow rates. . Especially, when the pressure of the high drainage hose in the water supply unit in which the tank is installed in the basement, a large flow of water can flow in the reservoir for a short time. In such cases, a continuous flow valve or a pressure reducing valve is required. Even if the water meter differs from the unmatched large or small pipe that is installed, there may be a malfunction or an inaccurate water quantity or a subsequent change in use state. .

Select the water meter according to the actual flow rate.
- When the diameter of the meter increases, the capacity increases but the sensitivity decreases.
- In contrast, if the diameter is small, sensitivity and accuracy are good. However, if a large amount of water goes through, overloading occurs and the durability of the water meter decreases. Therefore, do not select the meter based only on the diameter of the pipe, and select the appropriate type and size according to the actual flow rate.
- Due to the large difference in the amount of water used in the same water supply, depending on where the water is used, select the appropriate type of water meter.
