China's first medium and low speed maglev railway "sprint" trial operation
Recently, China's first medium and low-speed maglev railway with full independent intellectual property rights - Hunan Changsha low-speed magnetic levitation fast line test, speed of up to 100 kilometers per hour. This maglev express line connects Changsha South Railway Station and Changsha Huanghua Airport with a total length of 18.5 kilometers. Construction started in May 2014. It has entered the trial operation “sprint†stage and will be put into trial operation before the Spring Festival next year. By then, passengers will take the Maglev train from Changsha High-speed Railway South Station and take about 10 minutes to reach Huanghua Airport. Changsha Magnetic Suspension is China's first self-developed magnetic levitation line, which will use the low-speed maglev train “Wind Runner†independently developed by CZ Zhuzhou Electric Locomotive Company. The train was born in January 2012, and many achievements have reached the international leading level. China has thus become one of the few countries in the world to master the technology of medium and low speed maglev trains. Concerned about surprises

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed
of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
