Flowline AT12-1620 Flow Switch

Application Offered in liquid and gas sensor types, the general purpose flow switch package provides reliable no or low-flow detection of relatively clean non-coating media with a 16A compact flow controller for pump or process protection. Liquid examples includes water and sulfuric acid. The optional flash alarm brings attention to low-flow alarm conditions. Available in Polypropylene-Ryton and PVDF, the short flow sensor is used in pipe or ducting from 1/2" to 1 1/2", and the long flow sensor is used in 2" and up. The flow switch set point may be adjusted from 0.04 to 3 fps in liquids, or 1 to 90 fps in gases for low-flow control. The flow sensor is best applied in applications with relatively constant temperature. Fields of Application: Rugged Polypropylene-Ryton or PVDF sensor for corrosive liquids and gases Fail-safe relay control of pumps or valves with 0-60 second delay Polypropylene enclosure rated NEMA 4X with swivel base for conduit alignment Invert switch changes relay state from NO to NC without rewiring Optional strobe brings immediate attention to flow alarm conditions Solid state sensor is not damaged by over-ranging flow velocities
