The system to realize the automation of liquid level control is composed of hardware and software. The hardware mainly includes PLC touch screen and related CPU, memory, output and input, power supply and other modules. The on-site measurement includes all kinds of sensors and switches suitable for different on-site conditions. In addition, it also includes audible and visual alarm lights, control buttons and other related equipment. By configuring PLC liquid level display alarm instrument, it can realize the display of industrial field liquid level measurement, the alarm of high and low liquid level, as well as the opening and closing of pumps, valves and other equipment. It can realize unattended automatic workflow, greatly improve the production efficiency, save human cost, and bring about the increase of enterprise benefits, Lay the foundation for enterprises to take the lead in the severe competition in the future. Therefore, in the current situation, whether it is a new project or a transformation project, it is suggested that if conditions permit, starting PLC equipment is the priority.

Driven by major European markets such as Germany, Italy, the Czech Republic and France, the global PV inverter market grew by 140% in 2010. PV market analyst Tom Haddon said: "In 2010, demand growth, component shortages, many suppliers extended delivery time to 30 weeks. Who has the components who is the winner, Power-One is a best example."
Power-One, Siemens, Advanced Energy, Solar Power, and Danfoss have become the companies with the most market share growth in 2010. "The growth of the small three-level inverter market is between 10 and 20 kW, making Danfoss, Refu Elektronik and Siemens gain a lot of market share," Haddon explained.
It is expected that the North American market will continue its high growth momentum in 2011, which will benefit local suppliers such as Satcon and Advanced Energy. The two companies have performed very well in 2010, ranking highest among non-European countries' suppliers and the largest share increase. of. Advanced Energy was the third largest supplier of market share growth last year, mainly due to the company’s earlier acquisition of its rival PVPowered.
As oversupply in 2010 led to excess inventory, intense industrial competition, and the market balance is shifting to Asia and North America, suppliers will face different opportunities and challenges in 2011. Analyst Tom Haddon concluded: “In 2010, the photovoltaic inverter market was centered in Europe and over 80% of the products were shipped here. However, we expect non-European markets such as the United States, China, and India to grow rapidly to Europe. The increase in market share for suppliers in major markets will be limited."
According to the latest market report from IMS Research, Power-One has become the biggest winner in the growth rate of PV inverter market in 2010, ranking the second in the world. The report also showed that for the first time in 2010, the top ten suppliers all came from Europe, which was mainly due to the explosive growth of major European markets, which benefited these suppliers. The top five suppliers with the largest increase in market share in 2010 were Power-One, Siemens, Advanced Energy, Sun Power, and Danfoss.
