V10 Flotect® Flow Switch
The latest Flotect® Flow Switch from W.E. Anderson division of Dwyer Instruments, is the mini-size model V10. These UL recognized hermetically sealed switches feature a magnetic linkage for leak-proof operation; brass or stainless steel bodies for wide media compatibility. A patented switch adjustment allows fast changes between normally open and normally closed switch actions without removing the unit from service. 

The stainless steel vane, with removeable template can be easily trimmed for actuation/deactuation rates as low as 1.6/1.4 GPM water or 7.0/6.4 SCFM Air. A single model fits any pipe size from 1/2" to 2". With 1/2" NPT process connections, units are rated to 200 F and 2000 PSIG.
