Scully WL-102 2" Whistler Fill Signal Tank Alarm

The Scully WL-102 Whistler Fill Signal is an audible alarm that retrofits into the internal end of a vent pipe to notify fuel delivery operators when to stop filling, preventing costly spills and ruptured tanks. This economical unit installs with a special tool into the vent pipe, making it ideal for adding overfill protection to existing heating oil or fuel storage tanks.

Key Features:

• Whistles when the tank is filling, and when the whistle stops, the tank is full
• Designed for 2-inch vent pipe installations
• Calibrated whistle stems allow for product expansion
• Patented screen keeps the whistle chamber free from pipe scale and bugs
• Completely reliable and accurate with one-time installation that usually outlasts the life of the tank
• Made in USA by Scully Signal Company

The Whistler may be used for both new installations and in existing tanks which have been piped without a signal. This fail-safe device has been the industry standard for heating oil delivery safety since Scully revolutionized tank fill alarms in the 1930s. Part number 00404 ensures you receive the correct 2-inch model for your application.
