Description
Description Description Description Description
One or 2 electronic limit switches can be installed in the indicator housing to allow
initiation of signaling or switching functions on a preset flow value. The limit switch
operates as a slot initiator that is inductively actuated by a disc mounted on the pointer
shaft. Any flow value can be used for setting the limit value by sliding the initiator
along the indicator scale. Minimum setting distance between two limit switches is
approximately 40% full scale. The position of the initiator also serves to visually
indicate the set value. Settings can be adjusted by removing the indicator cover,
loosening, moving and retightening of the alarm indication needle, and replacement
of the indicator front cover.
