Drum Alarm (Low) Level, Polypropylene Material

DrumAlarm™ — Continuous Low Drum Level Monitoring for Chemical Drums

Never run out again! The DrumAlarm™ low drum level alarm provides continuous monitoring of liquid levels in chemical drums, ensuring you’re alerted before your supply runs dry. This battery-powered drum level sensor installs in seconds — simply connect the battery and suction line, and your system is protected.

Versatile Mounting Options for Every Container

The DrumAlarm™ chemical drum alarm is available in multiple mounting styles to fit standard industrial containers and chemical feed drums:

• Slip-Cap Mount (Most Popular): Quick-change design drops over the bung without threading, making it easy to move between drums.

• Threaded Drum Plug Mounts: Secure, vapor-tight seal options in NPS and Buttress thread — ideal for chemicals that release fumes or vapors.

• 3/4″ Bung Mount (DLK Series): Compact low-level drum alarms designed for smaller openings and tight installations.

Integrated Suction Tube — Always Monitoring

Unlike basic float switches, the DrumAlarm™ low level sensor includes a rigid suction pipe permanently attached to the float assembly. This ensures the level alarm can’t be separated or forgotten during setup.

• Continuous protection: Always monitors drum levels, preventing your chemical feed pumps from running dry.

• Precision adjustable depth: A convenient thumbscrew lets you lower the suction pipe to the bottom, minimizing residual chemical waste.

• Pump protection: Built-in 14×14 mesh intake screen (~1400 µm) filters out debris and crystallized chemicals.

• Optional check valve: Prevents pump de-priming and ensures consistent suction.

Reliable Battery-Powered Operation

No power outlet? No problem. The DrumAlarm™ drum level alarm runs on an included long-life lithium battery that lasts for years. It consumes no power until an alarm sounds, so you get uninterruptible performance — even during power failures or outages.

• Cord-free installation — perfect for portable or remote systems.

• Maintenance-free operation — no wiring, no recalibration needed.

Rugged Construction for Harsh Environments

Engineered for demanding industrial use, the DrumAlarm™ low level alarm system is built to last:

• Chemical-resistant materials:

  • Polypropylene – standard for 95% of applications

  • Kynar® (PVDF) – red-colored, ideal for highly corrosive chemicals

  • 316 Stainless Steel – for maximum durability in extreme conditions

• Loud warbling alarm tone easily cuts through industrial noise.

• Compression tubing connection prevents air leaks in chemical feed lines.

• Optional flow indicator models allow visual verification of flow rate and chemical clarity (available on all models except DLK).
