The IBC LOW LEVEL ALARM prevents running empty with a flashing LED and loud buzzer. 


Stop IBC tanks running empty…

  • Always on duty because the liquid tube is permanently attached to the alarm unit.

  • It can go anywere because it is battery powered. No need for power outlets.

  • Uninterruptible battery power lasts for years. Lithium battery included.
  • Loud warbling tone cuts through the loudest industrial noise.

  • Rugged. Built for rough, wet and corrosive environments.

  • Protects your pumps from debris with an intake screen.

  • No wetted metal parts.

IBC TOTE TANK ALARM for low liquid level makes sure your process will never run out of chemicals. When liquid level is low, an IBC Alarm emits a very loud 103dB beeping sound, and flashing LED.


Uninterruptible battery power works through power failures, can’t come unplugged, or be defeated. And, because the Drum Alarms don’t use any power until alarming, the batteries last for years.

Float switch is protected inside a pipe. The float is immune to abuse from getting knocked around during transfer between containers. Years of reliable service.



PVDF drum liquid level alarm

Adjustable depth to fit any size tote tank. Simply loosen the thumb screw to slide pipes to correct depth toa maximum of 50 inches. (this is slightly deeper than a standard 330 gallon Mauser IBC tank which is 48.5″)

Feed tube is permanently attached to the float switch, so the level alarm is always on duty.

Removable filter screen on the suction pipe guards your pumps from debris or crystals. A replaceable check valve can be easily inserted in-line to prevent liquid from draining when transferring to new containers if needed.

Check valve if the IBC will be transferred to different tanks by lifting it up and out then a check valve is a good idea to stop backflow of the chemical.  more info here

Push button to test the battery or to silence the alarm is included. Includes different field-settable behaviors like snooze alarm, tank filling modes. In the default mode the LED to continues to flash after the button is pressed to silence the buzzer. In the tank fill mode the LED and buzzer both turn off until the next high level event. (resets itself automatically) models have polypropylene floats, and polypropyelene piping so all wetted parts are polypropylene except the Acrylic flow indicator and glass ball. If Acrylic is incompatible there are models available without the flow indicator.

Different materials for different chemistries: polypropylene is standard. PVDF and stainless steel by request – contact us.


All models use a PTFE float switch for best chemical resistance.  The products divide along the lines of either having a liquid suction pipe included as part of the unit, or no liquid pipe. 

No-liquid-suction-pipe units are offered in Polypropylene pipe (ILK-PF) or Kynar pipe. (ILK-KF)

Units with liquid suction pipe can also be made from polypropylene parts or Kynar.  The wetted parts are the tubing connection fitting, the screen, the screen-mounting fittings. (ILPX or ILKX)

Polypropylene units pipe can have an optional flowmeter.  (ILP-PF)
