Flow Switches : AX1X

Thermo-Flo™ with Compact Flow Controller

 

     

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.

Features

 

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
