Flow Switches : GT10

Thermo-Flo™ Liquid & Gas Flow Switch

 

     

Application

Offered in liquid and gas sensor types, the general purpose flow switch provides reliable low or no-flow detection of relatively clean, non-coating media with one 1A relay output. Liquid examples include water and acetic acid. 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 as a low-flow alarm. The flow sensor is best applied in applications with relatively constant temperature.

Features

 

Rugged Polypropylene-Ryton® or PVDF sensor for corrosive liquids and gases

Adjustable set point with LED for flow or no-flow status indication

60VA relay selectable NO or NC via power supply wiring polarity

Solid state sensor is not damaged by over-ranging flow velocities
