Water Liquid Level Switch Contactless Detector Pan made it two layers

made it two layers

Size: 5mm x 2mm

and each one can have a different frequency

which means the same input values

please do not electrify

Water Liquid Level Switch Contactless Detector Pan made it two layersIntelligent non contact Level Sensor detector It adopts advanced signal processing technology and high speed of the signal processing chip, the thickness of the container will be less relevant for the measure level, and the high level of the sealed container, the true non contact measurement is made. The level sensor (detector) will be mounted on the top bottom of the outer container (The high level and low level), it will be useless to drill a hole
