Gizmo Engineering

Gizmo Engineering produces alarms. Our Drum Alarm® is a battery powered liquid level alarm that monitors liquid level in chemical drums tanks and containers. Our variable-area flow indicator is machined from cast acrylic for clarity and strength. Our check valve is useful for pumps that lose their prime. This valve prevents liquid from draining out of the feeding tube when transferring to the next drum. We also develop dual pump adapters.
