Overfill alarm for drums lets you pump liquids into chemical drums and containers. The high level Drum Alarm is quick and easy to install - lets you forget about overfilling forever. Simply drop it into a drum and you're ready to go! No wiring.
The mounting cap on the DHL-1 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 ammonium hydroxide.
