Precautions for installation and use of smart water meters

Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water usage, transmit water usage data, and settle transactions. Compared with traditional water meters that only have the functions of flow collection and mechanical pointer display of water consumption, it is a great improvement.

In addition to recording and displaying water usage electronically, smart water meters can also control water usage according to agreements, automatically calculate water fees for tiered pricing, and store water usage data.

Last time, I got to know what a smart water meter is. Today, let's learn together what to pay attention to during the installation process of a smart water meter! Smart water meters are quite familiar to everyone. In addition to recording and displaying water usage electronically, they can also control water usage according to agreements. However, some people use smart water meters improperly, causing great harm to the water meter. Therefore, I would like to share some precautions for using smart water meters:

Installation precautions and usage instructions for smart water meters:

1. The diameter of the smart water meter should be selected according to the diameter of the pipeline and the flow rate at the installation location, and the appropriate diameter of the smart water meter should be close to the commonly used flow rate.

2. Before installation, debris and sand in the pipeline should be removed to avoid causing malfunction of the smart water meter. If there are impurities in the liquid, filters or screens need to be installed at both ends of the smart water meter.

3. This smart water meter needs to be installed horizontally, and the dry smart water meter needs to be far away from the insertion field. The dial of the meter should face upwards, and the direction of the arrow on the case must be consistent with the direction of the water flow. The installation location should avoid exposure to sunlight, flooding, freezing, and pollution, and be convenient for disassembly and meter reading. During the rainy season and winter, measures should be taken to prevent rain and freezing.

4. During installation, a valve should be installed in front of the smart water meter to cut off the water source and disassemble the smart water meter.

5. When installing a smart water meter in a circular water distribution network or at the inlet of a boiler, a dedicated check valve for the smart water meter must be installed to prevent the meter from being damaged by reverse flow and hot water reflux

6. To ensure the accuracy of the smart water meter, the length of the straight pipe section (excluding valves and other fittings) directly connected to the smart water meter should be no less than 10 times the nominal diameter of the smart water meter.

Precautions for use:

1. Regularly check the operation of the smart water meter and pay attention to antifreeze in winter.

2. For those installed in pipelines but not yet delivered for use or those who do not use water for a long time (more than a week), please close the front and rear valves of the smart water meter. Our company will not be responsible for any consequences caused by this.

3. After replacing the battery, it is necessary to cover the moisture-proof cover and tighten the screws, otherwise the meter will not work and the card will display E-5.

4. If the electronic display of the smart water meter does not match the character wheel or if the smart water meter malfunctions, the character wheel measurement shall prevail.

Why is there a difference in the readings of the total and partial water meters for users in the total meter system?

According to the actual situation, the main factors causing the difference in readings between the total and sub meter water meters are as follows:

1. There is a leakage in the tap water pipeline and water supply facilities after the summary table.

2. The faucets of each sub meter are not completely turned off, and the sub meter cannot measure, while the main meter is measuring the water volume.

3. The sub meter has been in use for too long and has not been regularly calibrated according to regulations, or the quality of the water meter itself is poor.
