Optical Float®

THE OPTI-FLOAT® Level Detector

Combining new technology with a familiar device, the Opti-Float® level detector is a revolutionary innovation in discrete level detectors. It’s made of safe, recyclable materials. It’s mercury and lead free and is built to last for years of service.

The design of the Opti-Float® level detector is amazingly simple. Using fiber optic cable, it transmits a beam of light from an LED in a remote transceiver down to the float, where the beam makes and breaks depending on the tilt of the float. When the transceiver detects the presence or absence of light, it activates a relay in the transceiver, which can then operate other devices.
Now available in two models.
