(Reporter Yang Yang) The reporter learned from an interview with the environmental protection model city Wanli that at present, petroleum and chemical industries are the pillar industries in 47 national environmental protection model cities and 3 national environmental protection model cities. Among the 36 cities (districts), 72% of the total are listed.
Including Daqing, Dalian, Nanjing, Shenyang, Huizhou, Qingdao, Zhenjiang, Changzhou, Changshu, Rongcheng, Dongying, Karamay, Korla, and Dagang District of Tianjin. 36 large and medium-sized cities (districts) with petroleum and chemical industries as pillar industries The establishment of environmental protection model cities, these cities in the overall planning of the city and the adjustment of the layout of the petroleum and chemical industry, comprehensive utilization of energy and resources, environmental protection and improvement of human settlements and other aspects have been innovative, a number of emerging social civilization, economy, Sustainable development, good environmental quality, rational use of resourceful demonstration cities and a number of modern ecological oil and chemical bases.
It is understood that in the current urban environmental protection work in China, three major new problems have emerged, such as the urban environmental pollution marginalization, motor vehicle pollution, and the constantly growing urban ecological imbalance. The petroleum and chemical industry is not only the pillar industry of the national economy, but also a large household that consumes resources and energy and may cause pollution. The transformation of traditional petroleum and chemical companies with high technology, the development of circular economy and the road of sustainable development are important issues facing these cities in the future.
Ultrasonic water meter is a new type of
water flow meter, by detecting the ultrasonic beam propagation in the water and
tide by speed changes generated, which analyze and process water flow rate. Ultrasonic
water meter is the use of ultrasonic time difference principle, the use of industrial
grade.
Ultrasonic Water Meters have the following features:
low initial flow rate, wider measuring range, higher measuring accuracy, good stability
and no need to set parameters installed at any angle. No moving parts inside
the unimpeded flow element, is not affected by impurities in the water, and
long service life.
The
ultrasonic Water Meters have excellent low flow detection capabilities, which
can solve the problem of many traditional water meters, more suitable for water
gradient charge, more for conservation and rational use of water resources and have
broad market prospects and use,is a good product to as Home Water Meter.
