KRUEGER OF-1.5-20 Overfill Alert Gauge, 1.5 Inch NPT Opening, 20 Inch Depth, Galvanized Steel

Krueger OF-1.5-20 overfill alert gauge is a high-level visual indicator intended to warn when the tank is almost full.

• This gauge is a simple visual aid.
• The tank is almost full if the red indicator starts to rise into the viewing window.
• After installation, you may easily check the calibration during filling to see when the tank is almost full.
• The indicator's calibration is off. It only tells if there is an overfill or not.

• Krueger OF-1.5-20 overfill alert gauge features stainless steel bushing, rods & floats and aluminium constructed locking nut for prolonged use and durability.
• It has simple pop up mechanical design to encourage simple installations, optimal durability and inexpensive upfront expenses.
• This model has a 1.5 inch NPT male connection size that can read out measurements for standard tanks with depths up to 20 inches.
• It comes with a leak detection gauge and an overfill alert gauge for the user's convenience.

• Krueger Drum Alarms: These Dalarm (direct mount) and Ralarm (Remote mount) units offer visual as well as audible indication of tank levels. They feature a magnetic switch that triggers a 110-dB alarm and are powered by a 9-volt lithium battery. These models can be easily reset.
• Krueger LED At-A-Glance Accessories: They provide the remote reading capability to the mechanical gauge.
• Krueger Guard Gauge: This cover protects the exposed plastic components on top of the gauge.
• Krueger Glass Calibration: It offers protection against heat, gases and deterioration and aids in passing fire inspections.

Q. How to install a tank overfill alert gauge?

A.

• Nothing should be disassembled.
• Drop the gauge through the tank fitting just as it is.
• Tighten the aluminium bushing by threading it in.
• Avoid crossing the threads.
• The gauge is prepared to operate.

Q. When an overfill alert gauge fails?

A.

• The calibration assembly located on the tank's outside may damage and becomes illegible or worn.
• The connecting rods can separate or sustain damage as they expand into the tank.
• The float that rests at the gauge's base may fall off or become product-saturated (leak).

Q. How to maintain this Krueger OF-1.5-20 overfill alert gauge?

A.

• Once a month: Check the calibration is visible, legible and undamaged on the top of the unit once a month. (Instead of needing to replace the gauge entirely, these top components are simply replaced).
• Once every six months: Carefully remove the device from the tank after unthreading it. From the red indication down to the float, make sure that all the rods are joined together as a single unit. Additionally, check the float for leaks or damage. Manually raising the float arm from empty to full will check that everything is in working order and that the red indication travels freely up and down with the movement of the float rod.
