When properly mounted, this sensor will detect tank levels from 1 inch to 25 feet.PowerThis sensor requires 3.3V for operation. The Whisker.Block® power supply is 18V so a regulator to reduce the 18V supply down to 3.3V is required.MountingThis sensor is housed in a 2 inch tube that is installed in the top or lid of the tank facing downward with a clear view of the liquid being measured. Mounting requires a .922 inch hole through which the device can be mounted. Take care not to overtighten the nut.Compatible Whisker.Blocks®Part NumberWB1-9-xx-A4A4A5A5-0000-xxWB1-9-xx-A5NNNNNN-0000-xxWB1-9-xx-A5NNNNNN-2001-xxWB1-9-xx-A5A5NNNN-0000-xxWB1-9-xx-DCA5NNNN-0000-xxWB1-9-xx-DCA5A5NN-0000-xxWiringD6 Labs Ultra-Sonic DiagramRecommended Wiring:ConnectorPinSensor WireDescription11RedSensor power supply12 or 3Blue/Black0-5 VDC Analog Input14WhiteGround Reference
