Scully 2″ X 1 1/4″ Vent Alarm by Scully
The Scully vent alarm is a compact option for small to mid-size tanks. Best for buyers who want a straightforward vent alert without additional gauge features. The unit prioritizes audible notification to signal vent pressure changes or blockage. A limitation is that it focuses on vent alarms and may not provide a full fuel level reading on its own.
R W Beckett Corp 4517 KING Oil Tank Fill Alarm
This alarm is best for users who want a clear warning when an oil tank reaches a critical fill point. It’s suited for setups where preventing overfill is a priority, such as tight space installations or older tanks with limited monitoring. A potential limitation is that it centers on fill-line alerting and may not include a full gauge readout.

This model combines a vent alarm with a fuel gauge, making it suitable for medium-to-large tanks with 2″ fittings. It’s best for buyers who want a single unit that provides both vent status and fuel level at a glance. It’s important to verify tank depth compatibility (42″-44″) to ensure proper fit.
Scully 01413 Combination Vent Alarm and Fuel Oil Gauge for 42″-44″ Deep Tanks
Designed for 42″-44″ deep tanks, this unit provides both a vent alarm and fuel gauge in a 2″ configuration. Best for buyers who want integrated monitoring without multiple devices. A caveat is that installation requires correct threading and compatibility with existing fittings.
Scully 2 X 1-1/2 VENTALARM GAUGE 42-44 TANKS
This option merges vent alarm capability with a fuel gauge for deeper tanks in the 42″-44″ range and 2″ connections. It’s best for buyers who need both vent monitoring and fuel level indication in a single device. It may require careful alignment with tank depth and existing hardware.
