Potter Electric EVD-R Waterflow Pick-up Unit

Product Description

The Potter Electric Signal Co. US EVD-R is a waterflow pick-up unit designed for use in fire sprinkler and waterflow detection systems. This device senses water movement within a pipe and triggers the appropriate alarm signal when flow is detected. It functions as a critical sensing component within life-safety suppression systems, converting hydraulic activity into an electrical output for downstream notification or monitoring equipment. Licensed fire alarm technicians and sprinkler system contractors are the primary installers of this device.

The EVD-R is used in commercial and residential fire sprinkler systems where reliable waterflow detection is required. It is typically installed on wet-pipe sprinkler systems and paired with compatible alarm control panels or waterflow alarm switches. This unit is sold individually and suited for new installations as well as retrofit or replacement scenarios in existing waterflow detection assemblies.
