10 pieces level monitoring sensor non-contact liquid level sensor alerter contactless level monitor easy to use

one of the most notable features of the non-contact sensor is that it does not need to be perforated in the container, and the micro-vibration analysis principle allows the accurate height of the liquid surface to be continuously measured outside the container. the instrument does not need to be installed with a hole in the tank wall to install the sensor. the meter does not touch the liquid medium in the container or the gaseous medium in the container.
