Liquid Level Devices
Optional controls available from Gorman‐Rupp
may provide a means to automatically regulate the
liquid level. These control boxes may be con­
nected to the following sensing devices which per­
form
either filling or dewatering functions (see FIG­
URE B-4).
The internal wiring of the sensing devices
are different for filling and dewatering func­
tions. Be sure to follow the instructions in­
cluded with the option before making con­
nections.
S
Diaphragm Type: two fixed‐position sen­
sors (upper and lower) each contain a dia­
phragm which flexes with changes in liquid
level, thus activating an enclosed miniature
switch.
S
Bulb (Float) Type: a bulb raises or lowers
(floats) with the liquid level, thus activating
an enclosed miniature switch.
