1. The power switch operation. Switching circuit caused during intense and short current pulses of voltage drop intelligent electromagnetic flowmeter pictures, which are formed in the power line interference. 2. workers, families, medical RF equipment. Refers to intelligent electromagnetic flow Hospital, Technology Hall of those devices may cause interference to radio 150 kHz --400 GHz band, including induction heating, microwave heating, high-frequency welding, scientific instruments, medical equipment and other high-frequency Main meter wide spectrum distribution. 14. The gas discharge lamps, fluorescent rectifier, starter. They will be on the grid and the surrounding space electromagnetic disturbance generated. 15. The power tool. Power tools used in the building of electromagnetic flowmeters, series motor commutator may produce electromagnetic interference. 16. lightning strikes. Caused by lightning surge current up to 100 kA, a rise time of only a few microseconds. This may impact the current induced in the electric system of the building in a high surge voltage, if the buildings were directly hit by lightning, harassment produced will be greater. Intelligent electromagnetic flowmeter sales force since the instrument measuring quality assurance, Anhui electromagnetic flowmeters measure the force provided by the Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) (http://www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs.
