LOW LEVEL DRUM ALARM  warns of empty drums with a bright flashing LED and a loud beeper when liquid level is low.

DLA-PF-55G DRUM ALARM

Drum Low Level Alarm…

  • Always on duty because the liquid suction tube is permanently attached to the alarm unit.
  • It can go anywhere because its battery powered. No need for power outlets.

  • Uninterruptible battery power lasts for years. Lithium battery included.

  • Loud buzzer warble tone cuts through the loudest industrial noise.

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

  • Protects your pumps from debris with an intake screen.

  • Adjustable depth using a thumbscrew.

  • No metal parts to corrode.

LOW LIQUID LEVEL IN DRUMS monitored continuously with the Drumalarm™.  Quick and easy to install – simply connect the battery and your liquid suction line and you’re ready to go!

MOUNTING STYLES

Various mounting styles available for any container such as Slip Cap, NPS drum thread, and Buttress thread. Of these, the slip-on cap is the most popular. It makes transfer to new drums so easy since you don’t have to screw it in, instead, it just drops over the bung.

On the other hand, threaded drum plug mounting is more secure and can seal the drum when noxious vapors are a problem.  We also have low drum level alarms that mount in the 3/4″ bung when needed. These are known as the DLK series.

IMPORTANCE OF THE SUCTION PIPE

An attached suction pipe can’t be separated from the float switch, so the level alarm is always monitoring the drum level. (otherwise an operator could simply “lose” the alarm part of the unit and voila, you have no alarm) The rigid suction pipe ensures that your pump is always drawing liquid from below the alarm point.  At the same time, adjusting the depth to the bottom of a drum makes sure the maximum amount of liquid is extracted from your drums as the float switch leaves only millimeters of residue. 

LOW DRUM LEVEL ALARM FEATURES

A removable screen built into the suction pipe guards your pumps from debris or crystalized chemical. more info

In addition, the bottom of the pipe is designed to easily accept an optional check valve for pumps that can lose their prime.

Uninterruptible battery power works despite power failures, can’t come unplugged.  Because the Drum Alarms don’t use any power until alarming, the batteries last for years. Discussion on battery power.

Secure compression tubing connection eliminates air leakage into your feed lines.

Models with built-in flow indicator allows you to verify flowrate and inspect the solution. (applies to all models except DLK)

All low drum level alarms have a convenient depth adjustment with a simple thumbscrew. This allows the suction pipe to reach the bottom of the drum to extract that last liquid residue.

MODELS FOR ANY DRUM

Any container size – from 1 gallon bleach bottle to large tanks

  • DLA series incorporates a slip-on cap for fast drum transfers.  Includes flowmeter.
  • DLAX is the same thing but without flowmeter.
  • DLP models include a 2″ NPS threaded plug. (the fine drum thread) The ‘X’ in DLPX means no flowmeter.
  • DLB models have a buttress thread. (coarse – 1.5 threads per inch) The ‘X’ in DLBX means no flowmeter.
  • DLK series has no liquid suction pipe – its the alarm part only. Mounts in the 3/4″ NPT thread common on steel drums. An adapter will allow it mount on one of the 2 inch bungs.
  • DP denotes the Liquid Suction pipe only for applications that need it.

Polypropylene is the standard material as it is perfect for 95% of applications. But, in addition, we also provide Kynar (PVDF) or 316 stainless steel drum level alarms especially corrosive chemicals.

Weighted Pipe

Very dense chemicals like concentrated sulrfuric will cause the DLA drumalarms to float a bit in the drum.  The addition of some steel shot in the pipe, steel shot in drum alarmsealed in place with resin adds 400g to the pipe which keeps it down in any liquid. (this option is only applicable for DLA models)

Check Valve

Optional check valve for use with diaphragm pumps, it stops the liquid from draining out of the feeding pipe during transfer to a new container. Eliminates re-priming pump.
