At present, there are mainly two types of pure electric vehicles and hybrid electric vehicles in the market. Pure electric vehicles are completely powered by electricity and do not generate any exhaust emissions, thus having the lowest pollution. Hybrid electric vehicles can be driven by both fuel and electricity, and the assistance of electricity can reduce fuel consumption and exhaust emissions. Compared to the two, pure electric vehicles are more environmentally friendly and can better adapt to use in specific environments.

The verification of the metering accuracy of the factory water electromagnetic flowmeter adopts the clear water tank volume method, which is one of the methods commonly used by water companies.
In the condition of measuring the geometrical dimension of the clear water tank and reducing the error of each operation, a higher reference effect of comparison can be obtained. The principle of the clear water tank volume method is: using a high-precision steel ruler to measure the actual space plane size of the clear water tank and the water absorption well, and accurately calculate the actual plane area of ​​the clear water tank and the water absorption well. First adjust the water level in the clear water tank to a higher water level and close all the outlet valves.
After the water level in the pool is stable, use the clear water tank level transmitter again and use a high-precision steel rule to manually measure the water level of the clear water tank and the water absorption well, record the water level of the clear water tank and the water absorption well again, and record the accumulated flow of the electromagnetic flowmeter to be verified. . Finally, the height difference ⊿h of the clear water tank and the water absorption well is calculated to calculate the actual water volume of the clear water tank and the water absorption well. The actual water amount is equal to the height difference ⊿h multiplied by the plane area and the corrected water amount.
After the water level of the pool is stable, the water level of the clear water tank and the water absorption well is accurately measured by a clear tank liquid level transmitter and a high-precision steel ruler. In order to correct the error caused by the valve leakage of the clear water tank, the water level of the clear water tank and the water absorption well is measured again after a certain period of time, and the amount of water leakage per unit time is calculated to correct the water metering and reduce the error. Record the electromagnetic flowmeter accumulative flow to be verified, and the purpose of manually measuring the liquid level of the clear water tank and the water absorption well is to verify the accuracy of the liquid level transmitter. Then turn on the water pump and open the water outlet valve. After a certain period of time, close the water outlet valve to stop the water pump.
With the advancement of technology and people's pursuit of environmental protection and low-carbon modes of transportation, electric vehicles will become the mainstream means of transportation in the future. More and more car manufacturers are beginning to invest in the research and production of electric vehicles, continuously improving battery technology and range, and improving the performance and user experience of electric vehicles.
Application of Intelligent Electromagnetic Flowmeter in Water Plant
Since the smart electromagnetic flowmeter must be used continuously on-line, it is almost impossible to dismantle and transport it to the National Metrology and Measurement Center for verification. Therefore, it is necessary to verify the accuracy of large-diameter electromagnetic flowmeters used in the field. The verification of the accuracy of the electromagnetic flowmeter is very useful for the management of the electromagnetic flowmeter to ensure its accuracy and reliability, and to accumulate the original comparison data. It is also very useful for future verification and verification. The verification of the accuracy of the electromagnetic flowmeter can use the clear water tank volume and electromagnetic flowmeter calibration equipment.
