Scully WL-100 1-1/4" Whistler Overfill Alert Signal

The Scully WL-100 Whistler Fill Signal is an economical tank fill alarm designed to retrofit into existing 1-1/4 inch vent pipes. This audible alarm installs into the internal end of the vent pipe, providing a cost-effective way to add overfill protection to tanks that were originally piped without a fill signal.

Key Features:

• Audible alarm installed in the vent of the tank to notify the fuel delivery operator to stop filling to avoid a spill
• Can be used for both new installations and in existing tanks which have been piped without a signal
• Economical unit installs with special tool into the vent pipe
• Whistle stem is sized for 275 gallon vertically mounted tanks
• Calibrated whistle stems allow for product expansion
• 1-1/4 inch pipe size compatibility
• Stops costly spills and prevents ruptured tanks

The WL-100 Whistler provides reliable overfill protection for fuel oil tanks, heating oil systems, and other liquid storage applications. Installation requires the Scully Model WL-140 installation tool (sold separately). Part number 00402.
