Flow Switches

Eldridge Products, Inc. (EPI) Series 7000, 7100, and 7200 Flow Switches are rugged flow switches for gases. Our flow switches are built with the same components as our flowmeters and operate on the same prinicpals of thermal dispersion. They include two High/Low relays for High/High, Low/Low, and Low/High switch options. One second to thirty seconds time delay is a available as a standard, with automatic reset in one second upon resumption of non-fault flow conditions. Two LEDs provide verification that an alarm has been triggered. The flow switches are calibrated for your process conditions and the relay trip points can be easily set up in the field. Factory calibrated trip points are also available, at an additional charge.
