The price of the water meter and the installation of the water meter
In order to be more aware of the water consumption at home, nowadays, the water meter has become a must-have product for every household. Of course, I believe that most users also know it well. It is a flow meter that can correctly measure and allocate water resources. Measuring instruments, coupled with the strengthening of the supervision and management of water meters by the property now, make the installation of water meters a part that everyone pays more attention to.
Water meter price type
1. For a community with a certain scale, because residents are scattered in different units, it is troublesome for property to read meters and charge at home, so mechanical meters are usually used. The prices of such products are usually cheaper. You can buy it.
2. The price of home smart watches will be much higher than the previous one. For branded products, the price will be slightly higher, while the price of general small manufacturers is relatively cheaper, and the price of small workshops will be lower.
3. There is also a kind of remote water meter, which is more common in life. This kind of product can remotely transmit relevant data to the computer, which perfectly solves the trouble of door-to-door meter reading and improves the management efficiency of the water supply unit. The price of water meters is generally more expensive.
Water meter installation
There are two main types of installation fees for this type of product. One is billed on time. Generally speaking, it takes about 15-30 minutes to replace one. The labor cost is customized according to the local labor cost standard, and the other is billed by piece. Of course Prices vary in different regions. This type of method is highly artificial and the quality of products is easy to control, but the investment is slightly larger.
What are the precautions for water meter installation
1. Choose a water meter: Choose a water meter of the corresponding specifications according to the pipe diameter, flow rate, etc., to avoid damage due to excessive load. The specification of the water meter is the nominal diameter of its interface. Generally, the water meter is configured according to the nominal diameter of the pipe so that its flow will not exceed its maximum flow.
2. Determine the installation location: The water meter is installed in a place that is convenient for viewing, free from exposure, freezing, and pollution. Generally, the water meter on the introduction pipe is installed in an outdoor meter well, a basement or a special room. A small water meter for household use is directly installed on the water inlet pipe of each production. There should be a valve in front of the water meter. The housing of the water meter should not be more than 30mm from the wall. The distance between the center of the water meter and the other wall (end surface) is 450-500mm, and the installation height is 600-1200mm. In order to ensure accurate water meter measurement, the upstream end of the screw-wing water meter should have a straight pipe section 8-10 times the nominal diameter of the water meter. Other water meters should also have a straight pipe section not less than 300mm before and after. When the length of the straight pipe section before and after the water meter is greater than 300mm, the section beyond the pipe shall be led to the wall with an elbow and laid along the wall. The center of the pipe is 20-25mm away from the wall.
3. Decontamination of the pipeline: Before the water meter is installed, the dirt in the pipeline should be cleaned to avoid clogging. It is best to install a filter before the water meter.
4. Direction and location: The water meter can only be installed on a horizontal pipe, keep the dial level, and make the direction of the arrow on the water meter shell consistent with the direction of the water flow, and do not install it backwards. Valves should be installed before and after the water meter. For buildings that do not allow water shut-off or no fire-fighting pipeline, a bypass pipeline should be installed. At this time, a check valve should be installed on the back of the water meter, and the valve on the bypass pipe should be equipped with a lead seal. 5. Connection mode: when DN≤40, use threaded connection; when DN≥50, use flange connection.
In addition, before construction, it is best to install a filter and remove the dirt in the pipeline to avoid clogging. At the same time, it is recommended to configure the water meter according to the nominal diameter of the pipeline, and make the flow rate not higher than its large flow rate. , And choose the corresponding specifications according to the flow rate, pipe diameter, etc.
In order to maintain the level of the dial, Jianqi installed the product on parallel pipes, and kept the arrow direction of the shell consistent with the direction of the water flow. In addition, there should be maintenance valves on the front and back of the water meter and on the bypass pipe, between the water meter and the valve behind the meter. A water drain device should be installed. At the same time, in order to reduce head loss and ensure the straight flow of water in the pipe before the meter, a gate valve should be used for the inspection valve before the meter.
