Occupying the building, with a liquid level gauge installed on the outside; in other words, it’s an ultrasonic device. What is its stability like, and will it experience fluctuations? Can it meet intrinsically safe requirements?
External level gauges boast good stability and reliability. The \"micro-vibration analysis technology\" ensures the stability and reliability of external level measurements. As for the fluctuations you mentioned, the \"self-calibration technology\" enables automatic calibration, ensuring accurate measurement of the liquid level even in the presence of fluctuations. These two technologies were also developed by Dinghua Company. Currently, external level gauges are available in explosion-proof versions, intrinsically safe versions, as well as those designed for SIS systems and certified to SIL standards – they can be used with confidence!
