Liquid level indicator5101 series

The housing has 2 separate chambers. In the front chamber, behind a transparent lens, is a 2-color flag (half red, half white) equipped with a magnet. In the rear chamber is a magnet equipped float, free to swing with the action of the liquid’s level. The poles of the two (2) magnets are opposite creating a bi-stable interlocking condition. As the liquid level falls, the float and magnet swing down opening the magnetic coupling. This causes the flag to drop, exposing the red side and indicating a low liquid level. Accordingly, as the level rises, the magnet’s proximity is shortened causing a magnetic attraction to snap up the flag exposing the white side and indicating a satisfactory liquid level condition.
