Fujifilm ultrasonic flowmeter probe installation method and orientation. There are generally two types of probe mounting: the V method and the Z method, and experience has shown that the V method has a higher measurement accuracy than the Z method without affecting the signal reception. Since the V-method probe is installed for precise positioning, the measurement error mainly comes from the flow regime and ...

1. Method errors It refers to the error caused by the imperfection of the measurement method used, the imprecise theoretical basis, and the inappropriate modification and simplification of some classical measurement methods, that is, all the factors that are not reflected in the expression of the measurement results, but in fact these factors play a role...

The basic principle of vector control is to measure and control the stator current vector of the asynchronous motor, and control the excitation current and torque current of the asynchronous motor according to the principle of magnetic field orientation, so as to achieve the purpose of controlling the torque of the asynchronous motor. Specifically, the stator of the asynchronous motor ...

After years of development, the inverter (VFD) has begun to transition from a purely industrial product to a civilian field. The use of VFD can be said to have gone to the countryside, (constant pressure water supply) penetrated into thousands of households (inverter air conditioning). But after using it for a while, you will find that the failure rate of VFD is much higher than that of the average household ...

In order to achieve a more efficient and controllable operation of the motor, and avoid the waste of power of the motor drive system, the inverter came into being. However, due to the variety of motor load types, the functional requirements for the equipped inverter are also different, so how to choose the right transformer for the motor...

During the epidemic, citizens need to have their body temperature measured when they enter communities, companies, and shopping malls, and there are many questions about infrared forehead thermometers, ear thermometers and other appliances. The reporter interviewed experts from the Metrology Department of the Shanghai Municipal Market Supervision Bureau on the issues that the public was concerned about, and answered some questions about the forehead thermometer ...

The frequency conversion speed regulation function of the inverter (hereinafter referred to as -VFD) is to convert the three-phase power frequency (50Hz) AC power supply (or any power supply) into a three-phase AC power supply with adjustable voltage and frequency. Frequency conversion speed control device can also be sometimes called VVVF, which is mainly used to adjust AC motors (asynchronous or synchronous machines).

What kind of flowmeter can be used to measure the quantitative controller of diesel flowmeter, and how to measure it? A: Diesel flow quantitative metering, which can be performed using the flow quantitative control cabinet system, while diesel flow measurement, which can be measured using ultrasonic flow meter, ultrasonic flow meter, measurement precision ...

After the inverter runs uninterrupted for a long time, the high temperature generated inside has serious hidden dangers to the operation of the inverter, especially in summer. The ultimate operating temperature of the inverter inside the inverter is generally 125 °C, and the temperature of the inverter inverter module and IGBT can sometimes reach 110 °C.

Fuji Electric Systems Co., Ltd. will release the Fuji Mini UPS EX100 Series on October 5, 2010. This is a new series of high-efficiency uninterruptible power supply systems (UPS) with capacities ranging from 1kVA to 3kVA. Fuji Electric ...

The inverter is a device that converts the power supply into the power supply of the power conversion, which is between the power supply and the electrical equipment. The inverter is a typical power electronic device, and its hardware core is power electronic components and microprocessor chips. Power electronic components, input and output copper bars and front-end ...

Ultrasonic level gauge is a non-contact instrument that uses the principle of echo ranging. The echo ranging principle is also known as the travel time or travel time measurement principle. It emits energy waves through a device that can emit energy waves (generally pulse signals), and the energy waves are reflected when they encounter obstacles, and are reflected by a ...

On July 26, it was reported that Fuji Electric will increase the production capacity of a new generation of power semiconductors in 2024 to about 10 times that of 2020. Recently, it was reported that in order to cope with the growing demand for silicon carbide power semiconductors in the fields of pure electric vehicles (EVs), Fuji Electric plans to launch a new ...

With the conclusion of the 19th National Congress of the Communist Party of China, the spirit of the major conferences has been newly conveyed. Among them, General Secretary Xi Jinping said that in order to practice the concept of green development, we must establish and practice the concept that lucid waters and lush mountains are invaluable assets, and to protect the ecological environment is to protect productivity, and to improve the ecological environment is to develop the ecological environment.

With the use of lithium batteries as power sources in mobile phones, digital products, laptops, electric toys, military industry, new energy vehicles, portable medical equipment and other fields, the domestic lithium battery industry has developed rapidly.
