46-622 Series 3 Liquid Level Switches ASME B31.3 Construction
23
5.2 Specifications
For float operated units, minimum specific gravities and actuating levels vary depending upon the
material of construction code used with the unit.
N
OTE: The minimum specific gravities and actuating levels shown are for single switch units with 1" process
connections only. Minimum specific gravities and levels will change for multistage units and levels
will change for units with 1
1
⁄2 or 2" process connections. Consult factory for these changes.
*The level decals on the control identify the actuation levels for units with three switches at the corre-
sponding minimum specific gravity of the three switch configuration.
