Checkpoint™

The CheckPoint Series is the low cost water level control and was design specifically for use with a Program Logic Control (PLC) as a modern replacement answer for electrical float switches.
Perfect in any application you don’t have a big budget or are just tired of continuously needing to replace old style float switches. The ‘set-it and forget-it’ style of the CheckPoint ends the replacement cycle. The compact design, with sensor and control in one unit allows a PLC, BMS/BAS or one of our WLC systems to easily connect, offering effective, low space, liquid level control.

Nina™

The WLC Nina is a complementary, compact universal liquid level system for installation into any OEM control system or panel as the water level or liquid level control. A DIN Rail mounted 18 cubic inch, small‐scale version of the standard WLC Series that has footprint of 3″ X 2″, the Nina can run up to four different switching relays and monitor up to six different probe points on either 24VAC or 24VDC, which is all pre-set at the factory for your configuration. It has an intuitive LED lighting system for user friendly a testing. There are four relay outputs to manage these six single point sensors.

PROUDLY MADE IN THE U.S.A.
