Floating Ball Level Controller The floating ball liquid level controller is composed of floating ball, plug rod, etc. It is installed on the top of the container through the connecting flange, and the floating ball floats on the liquid level according to the principle of equal volume of liquid. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry spring of the floating ball liquid level controller is magnetically attracted to change the liquid level position into an electrical signal, and the actual position of the liquid is digitally displayed through the display instrument, Floating ball liquid level controller to achieve remote detection and control of liquid level.

The floating ball liquid level controller is designed according to Archimedes' buoyancy principle. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry reed of the floating ball liquid level controller is magnetically attracted, so that the resistance in the sensor changes linearly, and then the converter converts the change of the resistance value into 4mA ~ 20mA standard DC signal output, Realize the remote detection and control of liquid level.
[Original] optimistic commitment to lighting contract energy management - Qingdao Frank Microelectronics Chief Engineer Han Yurong
(China Lighting Network Liu Lixun) "Contract energy management has been introduced to China from abroad for many years, but this seemingly promising energy-saving model has emerged in China due to acclimatization and variability. Compared with the electricity consumption of other electrical appliances, it is still a relatively small part. However, with the deepening and prolonging of the financial crisis, various owners have begun to focus on energy conservation, and daily cost expenditure can be saved. Therefore, in this special case, Perhaps it will give new vitality to contract energy management," said Han Rongrong, the chief engineer of Qingdao Franck Microelectronics. Han Gong has been doing this for six years. In the reporter's impression, he is an optimistic, easygoing and cheerful person. All things are done by people. In the process of knowing people, you can recognize the essence of things by the way. Han Gong laughed and talked about the relationship with the lighting contract energy management. He said that he used to be a meter before, but because he believed in others too much, his company let his relatives cheated. He had experienced a gloomy period of time, he was depressed and wondered how to go in the future, but it was at this time his high school daughter said to him: Daughter needs a successful father! And sent him a book, "The World's Greatest Salesman." The daughter's encouragement made him re-energize. After careful and rigorous research on the market, he was ready to start the project of energy-saving lamps. When the idea came out, he was immediately opposed by most people around him. Because in 2003 the energy-saving lamps were still in the stage of development, due to the immature technology, the market was mixed, the competition was disorderly, and finally the whole energy-saving lamp industry was notorious. However, Han Gong has seen it at a glance and has made it clear that the energy-saving lamps will have bright prospects in the future. This turned the customer into an investor, and his company started. Once Han worked for a customer to complete the contract energy management service, the two of them slowly moved in and became friends. This customer is a Taiwanese. When he saw this special energy-saving lamp so energy-saving and power-saving, he felt that there was development, so he decided to invest in Frank and became a shareholder. This shareholder later brought another friend to invest in the stock. Han Gong finally summed up: It is the cause of cohesion. Turning customers into investors is really an interesting thing. Energy management has become a mere buying of lights. After buying an investment, it is natural to increase production and sales. However, in these processes, Han workers slowly found a problem. That is, energy management has become a buy-only lamp, not a service. We know that the model of contract energy management is generally a test replacement lamp source. After half a year of trial use, then from the savings of electricity, the owner gets 20% and the contract energy company gets 80%. In this way, generally two or three months contract energy service companies can recover the cost. But the owner is not stupid, it is easy to see this. After half a year of trial use, this special light source luminaire used in energy management eliminates the owner's initial suspicion and distrust of psychological factors, and most of them will buy Frank's high-frequency energy-saving lamps, but they do not adopt the contract energy model. The reason is simple, because the owners have already calculated the account, and purchasing high-frequency energy-saving lamps separately is more cost-effective than using the contract energy management model. This may be one reason why the contract energy model can't go on. Energy management people are also exploring the solution to this phenomenon. High-frequency energy-saving lamps, energy-saving and power-saving, although there are doubts, there is no solution, but Han Gong has never given up their energy-saving business. In recent years, Francon has developed a variety of lighting energy-saving products, such as high-frequency energy-saving lamps, it also has many different specifications, including a 6U, which can replace traditional light sources such as mercury lamps and metal halide lamps. In contrast, the test under the same conditions results in a power saving of 60%-89.5%. The T5 series is mainly used to replace T8 fluorescent lamps. The result of testing under the same conditions is 44.5%-75.1%. Han Gong said that he has done many engineering cases in many places, such as factories, badminton halls and so on. Overall, the customer's response is still very good, and now they are developing new products. For contract energy management, although it is now subject to many obstacles and restrictions in the country, such as mechanisms, models and other factors, it is a headache. However, Hangong firmly believes that its future will be better, and will continue to be optimistic about his lighting contract energy management business. Han Rongrong, Han Haorong, specializes in the research and application of plasma physics and solid-state luminescence theory and technology, serving Qingdao Frank Microelectronics Co., Ltd., mainly engaged in lighting energy conservation, contract energy management U-type and T5 straight tube high-frequency energy-saving lamps research and development and produce.
