At the base of NVC Lighting, the Huizhou base in Guangdong, the staff of NVC Lighting walked out of the workshop early in the morning, gathered in the industrial park, raised the banner, saying that they would not return to work if they did not agree with the workers' requirements.
At the NVC headquarters, employees even shot the banner "Schneider rolled out of NVC."
According to insiders, early today, less than 8 o'clock, NVC Lighting CEO Zhang Kaipeng has already arrived at the NVC headquarters office, but Zhang Kapeng has not yet appeared, and no member of the board has come forward to appease. Subsequently, the staff began to petition the local government, saying that the government is the owner of NVC.
At the end of May, when Wu Changjiang resigned, he went to the NVC lighting Huizhou base for investigation. At that time, many workers reported that the factory had not many orders, and there was less overtime, and the corresponding salary was not high.
In addition to Wu Changjiang’s own great appeal within NVC Lighting, dissatisfaction with wages may have contributed to the incident.
In an interview with the reporter of "Daily Economic News", Zhang Xiaofei, dean of the High-tech LED Research Institute, believes that it is irrational to raise the contradiction between shareholders to the suspension of the entire company. The further expansion of the situation will exacerbate the company's turmoil.

High performance
Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
