10mm 5 to 24vdc contactless water level sensor suitable for level sensing of water tower container bathtub aquarium from factory

non-contact sensors are used in a wide range of environments. when measuring toxic, corrosive, pressure, flammable, volatile, and leaky liquids, the measuring head and instrument are outside the container, so the installation, maintenance, and maintenance operations are performed. it does not touch the liquid and gas in the tank, and does not use valves or connecting pipes, which is very safe.
