Flotect Series V12 FLOTECT® Flow Switch

Low Cost, Wide Range of Chemical Compatibility, Flow Rates 0.5 to 5.0 GPM

Series V12 Flotect® Flow Switch is a low cost, versatile line of switches that can be used in a wide range of applications and configurations. Mountable in any orientation, the Series V12 Flow Switch utilizes a free moving shuttle that is displaced by the liquid flow, activating an isolated, sealed reed switch. Models can be used in media that is compatible with Noryl® GFN3, stainless steel and ceramic 1. FDA approved materials option has wetted materials of Noryl® GFN3, stainless steel and Teflon®.
