In the M4302-7807-1, downward switch height adjustment by the end user can be as much as 2\", and an upward adjustment can be as much as 9\". This would allow a series of tanks to use the same level switch configuration and provide easier field adjustments for low level indication. Multi-level indications can also be provided. The adjustment is done by loosening the compression fitting on the top of the 2’’-11.5 NPT pipe plug and moving the entire stem up or down as needed in the application. The M4302-7807-x series is manufactured with nylon ferrules in the compression fitting. These types of ferrules allow the end user to adjust the length multiple times. The retaining rings are not to be moved, unless the operation needs to be changed from normally closed to normally open. Features
