Installation methods/steps of Mbus remote water meter
From: 2020-07-06

Mbus remote water meter installation method/step:

1. Before installing the water meter on the newly laid pipeline, the debris in the pipeline must be rinsed before installation. Because the water meter slows down or stops, a large part of the reason is the hemp wire, iron nodules on the inner wall of the pipeline, and precipitation The sediment causes the water meter to stop, making the water meter more accurate and reliable.

2. The water meter should be installed so that the direction on the case is consistent with the direction of water flow in the pipe. The location of the water meter device should be as easy as possible to read and change the meter to prevent the place where the sun and the cold wind are directly attacked.

3. The dial of the water meter should be upward and not tilted. If the tilt will increase the frictional resistance between the water meter wing wheel shafts, and even cause the gears of the water meter to mesh incorrectly, the sensitivity of the water meter will decrease, and the water meter will move more slowly with the increase of the tilt angle.

4. The practice of installing the meter out of the house is now being implemented. Because the working environment outdoors is much worse than that of indoors, the common water meter set concentratedly set outdoors has been exposed to sunlight and rain for a long time, and the gears in the water meter are in a high temperature state for a long time Deformation and aging greatly affect the measurement accuracy of the water meter.

5. Even if it is used for a long time in a normal working environment, the dial to which the pointer of the water meter is facing is prone to dirt, which covers the scale and prevents the meter reader from reading accurately. Therefore, the water meter installed outdoors should generally be equipped with a protective box.

6. The installation of some water meters does not meet the requirements, because some are restricted by the installation space conditions, and some are due to the lack of technical knowledge of the installer. For example, the water meter is installed immediately after the valve. The water meter should be installed horizontally. Make the reading convenient for wrong operations such as turning the dial that should face upwards to the side.
