AI Technical Summary
Existing concentration meters/instruments produce unstable measurement results when detecting the concentration of liquid/volatile gases inside a tank, as the liquid/volatile gases cover the measuring end, leading to inaccurate results.
The measuring end of the concentration detector is repeatedly wiped with a scraper. The scraper is driven by a drive structure to scrape the lens, keeping the detector clean. The drive structure, including a swing cylinder, drives the scraper to swing, ensuring the lens stays clean during the detection process.
This improves the accuracy and stability of liquid concentration detection inside the tank, ensuring the reliability of the detection results.
