The Flow Rate Alarm is a rugged “flow switch” device that monitors flow and sends a signal using simple on/off logic if rates are out of spec. The weather tight NEMA 4x cast aluminum enclosure allows for outdoor installation and washdowns. Alarm settings are easily adjusted in the field with an allen wrench. The standard Hirschman interconnection provides easy installation and maintenance.
