Plastic Flowmeter is a widely used instrument in water treatment engineering, mainly used for flow detection, usually installed after the water pump, to control the water intake of each structure, currently the most widely used are electromagnetic flowmeter and ultrasonic flowmeter.
In the selection of the flowmeter, the first thing to consider is the corrosiveness of the measured medium to the flow-passing parts, so as to avoid affecting the service life of the flowmeter due to the corrosion of the medium;
During the design and installation process of the flowmeter, the length of the straight pipes before and after the flowmeter needs to be considered. Usually, the principle of 5D before and 3D after the flowmeter is followed. Here, D is the inner diameter of the pipe. If the length is insufficient, the measurement accuracy will be affected. When using an ultrasonic flowmeter, the distance between the first 10D and the rear 5D must be met, and the distance from the flowmeter to the water pump must be more than 30D.
When selecting the type, the flow rate of the medium in the pipeline needs to be between the maximum value and the minimum value of the selected flowmeter, and avoid approaching the maximum or minimum value, so as to avoid affecting the measurement accuracy.

In solar arrays using power optimizer technology and distributed MPPT, each panel is connected to a power optimizer device. The power optimizer performs dual tracking: On the one hand, they track the best local MPPs; on the other hand, they convert the input voltage/current into different output voltages/currents to maximize the energy transmission in the system. The power optimizer communicates with each other in an indirect way. They have cognitive and self-organizing capabilities, can detect their own current and voltage environment, and self-adjust until the entire row reaches the optimal value, while reaching a local optimization point at the panel level.
At the same time, the power optimizer architecture is perfectly compatible with existing multi-level inverters, which will allow them to operate more efficiently because the bus voltage can be kept higher and more constant. The power optimizer is not limited to improving the DC/DC converter performance. They can both handle the energy surplus and can handle the energy reduction situation, which means that the panel due to the reflected extra light can be treated like various shadows. Does not match; Similarly, this means that the power optimizer has the ability to cope with power changes by adding panels to a row (making the row generate more power) or by reducing one or two panels from a row (thus reducing power ). Field tests show that SolarMagic chips can recover more than 57% of lost power. With SolarMagic technology, users can easily upgrade the system after installation of the solar system for many years, significantly increasing the power generated by the photovoltaic system.
In addition to reducing the amount of power generated by photovoltaic systems, SolarMagic technology has a high degree of flexibility. This allows PV system retailers to have more room to work on new system designs. For a long time, the system design engineers had to reduce the solar panels and ensure that the solar panels were not affected by shadows. This overlooked the aesthetics of the exterior design and the entire design process was time and money consuming. If SolarMagic technology is used, system engineers can not only improve the power generation efficiency of the curettage system, but also can be more flexible and beautify the shape design, for example: use different lengths of the battery board, match the different brands of the battery board together, and even use the irregular shape Solar panels.
The practicality of SolarMagic technology has greatly expanded the potential market of solar energy systems. By recoiling power generation losses due to actual environmental factors, the availability of SolarMagic technology allows photovoltaic systems to be installed in more locations. Many places that are considered unsuitable for installing photovoltaic systems can use SolarMagic technology for solar energy utilization.
Recently, SolarMagic Power Optimizer launched by National Semiconductor Corporation fully utilized the company's analog power management chip technology. Even if the solar photovoltaic power generation system is subject to the actual operating environment such as shadows, debris, and solar panel aging, this power optimizer is still Can reduce the decline in power generation. A change in the existing solar photovoltaic system architecture is vulnerable to the impact of the actual operating environment.
