Scully VS-201 Tank Fill Alarm Signal 1-1/4 Inch

The Scully VS-201 Ventalarm Signal is an audible tank fill alarm designed to prevent costly overfills and spills during fuel or oil deliveries. This whistle-type alarm produces a clear audible signal when air is released during tank filling, and the whistle stops when liquid reaches the vent opening—indicating the tank has reached safe capacity.
