Hand in hand with Colombo, made in China goes abroad

In 2015, the national water authority of Sri Lanka launched the "zoning metering and pipe network facilities reconstruction project" in Colombo. The project is a loan project from the Asian investment bank, and the general contractor is CAMCE international. Among them, the design and implementation of zoning metering are undertaken by the open flow instrument. The total investment of the project is USD 160 million, and the main objectives are to increase the scope of water supply, build the zoning measurement of urban water supply pipe network and transform the pipe network facilities.

Irrigation ● USA

The irrigation area of the United States is 1999 million ha, of which 11.11 million ha is furrow irrigation, accounting for 55.6% of the irrigation area, and sprinkler and drip irrigation account for 27% of the irrigation area. Underground irrigation technology has also been applied. The United States has good support conditions for the research and development of modern irrigation technology, and the U.S. Bureau of reclamation and other institutions are all over the United States, Provide good technical support for irrigated agriculture according to local climate and water source conditions. The irrigation water price in the United States is based on the average cost price, including operation and management costs, as well as the additional fees paid by the government to protect water resources. The water fee is charged according to the water consumption. The U.S. Bureau of reclamation uses automatic control technology for irrigation water distribution scheduling, combined with accurate metering equipment to improve water distribution efficiency.

Colombo is the capital of Sri Lanka, with a resident population of about 650000. In recent years, due to the aging of water supply network and the lack of management measures, the leakage rate has been maintained at a high level of about 40% for a long time. In order to alleviate the current water supply situation, the Colombo Water Authority officially signed a strategic cooperation agreement with Shanghai Kailiu in 2016, and officially launched the zoning metering and pipe network facility reconstruction project. The project mainly includes the primary district measurement in Colombo and the replacement of trade settlement statements of some industrial and commercial users. At the same time, the background leakage of pipe network is gradually reduced by means of regional pressure reduction.

For water measurement, electromagnetic flowmeter has won a solid market share and reputation in the agricultural irrigation market in various states. The agricultural irrigation market in the United States still has a lot of room to rise. Different instrument lines need to be introduced for different market needs. The agricultural irrigation market needs the reliability of products and services, that is, high manufacturing quality and low failure rate.

The construction of irrigation project needs to correctly master the method of measuring flow in irrigation system. At present, there are two main methods, namely velocity area method and hydraulic method. Each measurement method has its unique flow sensing (detection) part. For the application characteristics of irrigation systems in the United States, the electromagnetic flow products of open flow instruments have been developed and applied since 2014.

Through the implementation of the two-year plan, Colombo has been divided into five primary measurement zones; At the same time, according to the revenue data of the water department, some large water users have been replaced with high-precision electromagnetic water meters and remotely monitored; 28 pressure monitoring points are added to the pipe network. By the end of 2017, the leakage rate had been reduced to 32%.
