The Skimmer Guardian uses a optical sensor with a magnetic mount. The magnetically coupled sensor makes it easy to install and adjust to the desired level on the collection cup. The sensor is mounted externally so no holes are required in the collection cup for installation. If the level in the cup reaches the sensor, the Skimmer Guardian will shut down onthe skimmer pump immediately to prevent your cup overflowing. A built in auto time delay also prevents false alarm due to power outages. Once the skimmer cup is drained the Skimmer Guardian will restart the pump.
