Pipeline leakage is a thorny issue for most of the water companies, and it is also one of the important reasons for the poor production and sales of water. For loopholes hidden in underground pipelines, the past can only be checked manually and it takes a lot of time and manpower. Nowadays, Smart Water Services has given us a brand-new approach. Only by slightly modifying the pipe network and installing a high-precision intelligent water meter can we achieve a very good monitoring effect of leakage leakage.
QuesTIon: How does smart water reduce leakage?
A program called "Divisional Measured Leakage Analysis of DMA Zones" provided by the Hewitt Waterworks Intelligence Platform, as the name implies, is to analyze the leakage through the water supply measurement in the subregion. The specific implementation process is as follows:
Ø Water supply network level division: According to the actual situation, the water supply pipe network is divided into different levels, for example, a district in the city is set as a first-level region, and a residential concentration zone (or street) is set as a second-level region, and the community is set to three levels. Regional, then the entire city pipeline network will be divided into several layers, and each layer of water supply theoretically should be the sum of the next layer of water supply.
Ø Add “Intelligent Water Meterâ€: transform the water supply pipe network, and add a high-precision intelligent remote water meter of corresponding caliber to the total pipe section of the regional pipeline network at various levels to collect the total water supply of the area and upload it to the data center.
Ø Analysis and investigation: Finally, through the Haiweizi smart water management platform, online viewing and comparison of the data of the regional total tables, you can understand the loss of tap water at all levels of the pipeline, and effectively screen out areas of the network where the leakage is more serious. Arranging personnel to carry out targeted repairs, avoiding the time and manpower waste brought about by blindly leaking leaks, and improving the efficiency of leakage control.
QuesTIon: Why must "high-precision smart water meter"?
In fact, the “divisional measurement and leakage reduction†program was proposed by some people long ago, but it has not been implemented on a large scale in China. There are two reasons: First, the rules in China’s energy supply sector are not yet perfect. Before that, the country’s water leakage leakage rate There are no mandatory requirements for control, and the awareness of water saving for the entire nation is not fully awakened. Second, leakage analysis needs to add or subtract data from multiple tables. Therefore, the accuracy of the collected data is more demanding. In the past, mechanical meters were mostly used. Cannot meet the requirements.
For example, the total amount of water supplied by all households in a certain district is 14% less than the total number of records in the total district. It can be inferred that there may be a large leakage in the water supply pipeline of the community. However, in fact, all household water meters are mechanical water meters with a high initial flow rate, and do not count the small flow rate. Therefore, the 14% difference is meaningless because it cannot be determined whether the deviation is due to a leakage or a measurement error. The actual leakage may only be 5%.
Therefore, only by minimizing the error of the water meter, can the district measurement achieve the desired effect. Today, Hewitt has an ultrasonic electronic remote water meter in the large-diameter field, and Hamik's non-magnetic remote electronic water meter in the small-caliber field. Both are high-precision water meters with leading-range ratios in the market and can be measured for the subarea. The calculations provide reliable data so that loopholes in the pipe network are nowhere to be seen.
QuesTIon: Why do we want to reduce leakage?
Ø National requirements: In 2015, the State Council issued the “Water Ten Article†to require that the basic leakage rate of the national public water supply pipe network reach the national secondary standard of 12% by 2017; by 2020 it must be controlled to reach the national first-level standard, ie 10 %. According to data from China Water Network, the average leakage rate of tap water companies in all parts of the country was still as high as 15% in 2014.
Ø Water-saving needs: 15% leakage rate means that for every 10 tons of water supplied, there will be a loss of 1.5 tons. In general, it is said that water will be lost to a person when water is supplied to 7 individuals. Water resources will be higher than the world's recognized "water stress" line. If the leakage can be reduced to 5% or less, it will be a milestone progress in the water saving operation, and the water tension in China will also be greatly improved.
In view of the above, it can be said that reducing the leakage rate is a matter of everything: replacing the Hammak non-magnetic water meter, setting up a smart water platform, and implementing zoning and metering. These High Weitz can do it for you and help you reduce leakage easily. Rate, to meet national standards, save more water!
RCA Cables can be used to connect a variety of audio and video devices, such as camcorders, to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the device goes through three separate channels-one video and two audio-resulting in a high-quality transfer. Lower-end camcorders usually have only one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.

Quality of RCA Cables
Several factors affect the quality, price, and performance of RCA cables:
Materials: The connectors on RCA cables are often gold, silver, or copper. As you might expect, the gold connectors are the most expensive. They're also better than silver and copper connectors at preventing oxidation, but not as good at electrical conductivity. The silver connectors are best for electrical conductivity with the copper cables coming in a close second and the gold cables falling far behind. Other suitable materials are nickel, zinc, and tin.
Cable Length: Cable length has a negative effect on signal quality. Buy a cable that is only as long as you need it to make the connection for the best signal quality.
Shielding: A well-shielded cable delivers a better signal than one that lacks robust shielding.
The other end of the cable: If possible, match the material used in the other end of the cable to the material used in the connectors. Don't match tin with gold or silver with gold. Those combinations can cause problems because of an electrolytic reaction.
