Gizmo Engineering Drum Alarm-High Level Polypropylene Threaded Plug Feed Pipe 7 Depth Battery DHP-PF

Dhp-pf is a high-level drum alarm designed to provide reliable overfill protection for chemical and process drums equipped with a 2 inch nps bung connection. It combines a rugged float switch assembly with an integral feed pipe loud audible alarm and bright visual indication to warn operators before a drum reaches a critical level. This compact self-contained unit is ideal for automatic feed systems where uninterrupted unattended operation is required and where spills or overflows would be costly hazardous or environmentally damaging. By integrating the feed pipe and float in one assembly the dhp-pf helps ensure that the alarm always stays with the drum's fill line reducing the risk of operator error and improving overall plant safety. As part of gizmo engineering's high-level drum alarm family the dhp-pf is the threaded plug model with integral feed pipe distinct from slip-on cap versions or alarms without feed piping. It is particularly well suited to automatic pumping or metering systems where chemical is fed through the drum's bung since the feed tube is welded to the alarm assembly so it cannot be left behind. Typical applications include chemical dosing for water treatment plating and surface finishing baths industrial cleaning and cip systems and any process that continuously draws from bulk drums. By coupling robust mechanical design with independent battery power and clear audible and visual alerts the dhp-pf offers a practical maintenance-light solution for preventing overfills and improving compliance and housekeeping in drum-based chemical handling operations.
