Mini-Float Liquid Level Switch
LV20 & LH25
Application
Offered in vertical and horizontal configurations, the
general purpose mini-float level switches provide reliable
liquid level detection of clean water and chemical
solutions with a 50VA or 30VA reed switch output.
Media examples include water and sulfuric acid. The
polypropylene or PVDF liquid level sensors are mounted
vertically inside the tank or horizontally through the tank
wall as a high level alarm or low level alarm.

Remote Level Controller
The general purpose remote level controller is offered in three configurations for
pump and valve control. The LC40 accepts one level sensor input and provides one
10A relay. The LC41 accepts two level sensor inputs and provides one latching 10A
relay for automatic fill or empty control. The LC42 accepts three level sensor inputs
with one latching 10A relay output for automatic fill or empty control, and a second
LC4X
non-latching 10A relay for high or low level alarm. For field mount installation, add a
single or dual indicator NEMA box.
Key Benefits
Simple Level Switch for clean and water like
applications
Switches can wire directly to a PLC/SCADA or
controller
Switches can be converted in the field from NO
to NC.
SWITCH-PRO™
Compact Level Controller
The general purpose compact level controller is offered in two configurations for
pump and valve control. The LC10 accepts one level sensor input and provides
one 16A relay for high level control or low level control. The LC11 accepts two
level sensor inputs and provides one latching 16A relay for automatic fill or empty
