IBC TOTE TANK ALARMS for high liquid level makes sure you never overfill an IBC. When liquid level reaches the float switch, the IBC Alarm sounds a very loud warbling buzzer and flashing LED.  Pressing the silencing button in response to the alarm mutes the buzzer, while the LED continues to flash. (in the default mode) Beyond the basic behavior, the IBC alarm can be adapted to almost any level monitoring situation. For example, our customers have requested things like connection to solenoid valves, PLCs, automatic emptying, relay outputs, and much more. If you need to control the process of filling an IBC, we have you covered.

CONSTRUCTION

Float switch is protected inside a pipe to protect it from physical damage. This means you don’t have to worry about it getting damaged if it’s taken out of the IBC. And since the alarm may often be transferred from container to container, it makes sense to protect the float switch from damage. This feature is unique to Gizmo Engineering.

Uninterruptible battery power works through power failures, can’t come unplugged, or be defeated. Usually the batteries will last for years but when they eventually do run down, there is a low-battery alert built in. In addition, we also provide line-powered IBC high level alarms if this works better for you.

OPERATION

When an alarm is given, the pushbutton on the electronics enclosure silences the buzzer while allowing the LED to continue flashing as a reminder that there is still a level condition present.  Every 30 minutes the buzzer will sound again.  This behavior we call the “snooze alarm” can be disabled if desired with a jumper on the circuit board inside. When the IBC high level alarm is not actively in the alarm state, the push button  tests the circuit.

Adjusting the depth is done by simply loosening the thumb knob on the lid and positioning the pipe to the desired depth by hand. (no tools are required for this)

MATERIALS

The most popular materials is polypropylene because it generally has better chemical resistance than the polyethylene that plastic IBCs are made of. There are very few aqueous chemicals where polypropylene doesn’t outperform that of the IBC.

(the short list of aqueous chemicals where polyethylene is actually better than polypropylene is: acetic acid, benzoic acid, bleach, chlorobromomethane, phosphorous trichloride acid, and pyridine)

For cases where another material is needed, we also fabricate IBC level alarms from Kynar (PVDF) or 316 Stainless steel.  Also, for Hazardous Locations we adapt our Intrinsically Safe level alarms.

 MODELS

The different models of IBC high level alarms are separated by the presence of a liquid feed pipe or fitting, or just the alarm function only. In either case, the standard working depth (this is the depth of the float pipe inside the tank) is 10 inches.

IHP models have a liquid feeding pipe that goes through the center plug in an IBC lid. (So both the alarm pipe and the liquid pipes are mounted through the plug)  These are available in polypropylene, or for maximum chemical resistance, Kynar. The depth is adjustable to a maximum of 10 inches.

IHK models do not have a liquid feed pipe.  This model consists of a single pipe which contains the float switch at the bottom end.  This pipe is mounted on a flat IBC lid with no screw-in plug in the center.

This makes it easy to add other options like a cam-lock elbow to feed liquid through the IBC lid. Thes are also available in polypropylene or Kynar pipe.
