In process of electromagnetic wave peak welding

liquid level fluctuation size is a very important parameter and if fluctuations of tin fluid level is relatively large

then the product will likely cause welding problems

therefore

fluctuations in the level of electromagnetic wave real-time monitoring is very important. By using non-contact level measurement system

which components of level measurement modules

Arduino controller and the computer

to measure the tin fluid level fluctuation of electromagnetic wave. Liquid level fluctuation value and level fluctuation curve image will be displayed by Lab VIEW virtual instrument software. When the level exceeds the maximum fluctuation or below the minimum level set by fluctuations settings

which the fluctuation ranges of the pre-set level

an alarm will be given and timely feedback to improve the quality of welding. Volatility level experimental measurements consistent with the expected value by measurement and verification

very smooth.
