TANK LEVEL ALARM
DRUM ALARM - HIGH LEVEL

The DRUM ALARM for HIGH LIQUID LEVEL alerts your attention to full drums with a bright flashing LED and a loud beeper when liquid level is high. Just drop it in a drum and never overfill again!

A Better Overfill Alarm...

  • Always on duty because the liquid feed 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 always included.
  • Loud warbling tone cuts through the loudest industrial noise.
  • Rugged. Built for rough, wet and corrosive environments.
  • Transfer to a new drum is easy: no need to screw in threads or fiddle around with tube connections, just drop it in.
  • A functional check is simple - just lift the Drum Alarm out of the drum.
  • Safe. 9 volt circuit in a waterproof enclosure.
  • No wetted metal parts.

Overfill alarm for drums lets you pump liquids into chemical drums and containers. When the level gets above the float switch, an alarm sounds and LED flashes to let you know.

Easy to install the high level Drum Alarm: simply drop it into a drum and you're ready to go! No wiring. Lets you forget about overfilling for good.

The mounting cap on the DHA-5 Drum Alarm makes it easy to switch to a new drum when the old one is full since you don't have to disconnect tubing while you unscrew a cap - it just drops over the bung. The cap keeps debris out of the drum, and suppresses vapors even liquid ammonia.

The attached feeding tube on the DHA-5 and DHP-7 Drum Alarms make sure the alarm stays with the alarm so an operator cannot forget it. Your tubing is secured with a foolprooof polypropylene compression fitting to eliminate chance of spillage due to hose disconnection.

Float switch is protected inside a rigid pipe so it can get knocked around without worry.

Adjustable depth on all models with no tools required. Just loosen the thumb knob and slide the pipe to set the desired depth.

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. Nevertheless a test button is included on all models.
