Shanghai World Financial Center Case - DTFX1020B Time Difference External Clip Ultrasonic Flowmeter

Shanghai World Financial Center is a skyscraper in Lujiazui, Shanghai, China, completed on August 29, 2008. It is the second tallest building in China, the third tallest building in the world, and the tallest flat-top building in the world. It is 492 meters high and 101 floors above the ground. The developer is the “Shanghai Global Finance Center Company” and is led by Nippon Sen Building Company (Mori). build.

Scene description: Shanghai World Financial Center installed a DTFX1020B clamped ultrasonic flow meter with thermal capabilities. It is mainly to measure the heat difference between the inflow and return water of air-conditioning circulating water. Among them, the cold water and hot water are fed into the water and backwater. The pipes are all carbon steel pipes, DN125-DN150. The inlet temperature of the cold water meter is lower than the return water temperature, and the inlet water temperature of the hot water meter is higher than the return water temperature. This point should be noted when installing. Solution: The original Shanghai World Financial Center is a mechanical meter used by a certain manufacturer in Ningbo. In the summer, it uses less hot water (again, less cold water is used in winter). The mechanical water meter has no instructions, but it involves the building's trade. Settlement obviously does not meet the requirements. Recommended by New Japan Air Conditioning, because of the customer's site can not stop the water, high pressure (25MPa) and other characteristics, our technicians use ultrasonic clamp type with heat meter, to solve the customer's small flow can not be detected, can simultaneously detect the flow and heat, etc. Function, at first the customer used our instrument and found that our instrument is hundreds of tons more than the mechanical instrument every month. The customer asked us to give an explanation. Our company sent someone to the site to view it. Finally we asked the customer to close all the valves. Under the circumstances, the zero point was detected. Finally, we discovered that the meter was still available. After inspection, it was found that there was a toilet valve that was not closed. Because the mechanical meter was unable to detect the small flow, the customer was quite satisfied with the precision of our company's meter and decided to purchase it immediately. 20 sets of meters have been installed for more than two years, and the effect is quite good. At this point, our company's instrumentation has become a qualified supplier of Shanghai World Financial Center, and our company's product measurement is accurate, which also provides great convenience for the building's measurement work. Installation will not affect the normal water supply of the building, which also reduces the customer a lot of unnecessary trouble.

Application effect: After installation, the site operates stably and the measurement accuracy is high. This solves a lot of unnecessary troubles for the customer. The customer is very satisfied with the service attitude of our after-sales service engineer.

Round Molded Graphite

As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.

The high-purity graphite, graphite block and Molded Graphite produced by Pingdingshan Carbon Graphite Factory for many years are excellent, and the specifications of Round Molded Graphite are as follows: φ 450*800, φ 520*400 φ 630*420, φ 660*620 φ 780*600, φ 820*350~500 φ 900*350~400, φ 1050*350~400 φ 980~350*400, φ 1160*350~680 φ 1260*350~680, φ 1330*400 φ 1420*400, φ 1520*400 φ 1630*350, φ 1800*350 φ 2000*350, φ 520~2000*680
