Designed
to provide an inexpensive, reliable unit to monitor
the presence or absence of flow in a system. The V10 and
V11 flow switches are used to monitor unattended equipment
and protect it from costly damage. The V10 flow switch utilizes
a rugged, hermetically sealed reed switch which is encapsulated
in a polypropylene switch housing that fits into a standard
heavy duty leak proof brass body or optional 303 Stainless
Steel body. The patented switch adjustment allows the user
to change the switch to Normally Open (NO) or Normally Closed
(NC) in the field merely by loosening two screws. The switch
housing is located outside the process media, making switch
change-over or maintenance easy without interruption of
process flow.
The V11 Flotect® flow switch takes our very
popular V10 design and adds rugged, integral electrical
wiring. The one-piece PBT switch housing snaps onto the
body and the wiring is epoxy sealed making the switch weatherproof,
meeting NEMA 4 standards. The 22 AWG cable used is UV resistant,
flame retardant, and comes standard 6 feet in length. This
unique design eliminates the need for running conduit between
the switch and panel, lowering installation costs.
A full size, trimmable stainless steel vane
is provided with a removable laminated template. This template
is calibrated for brass or ductile iron reducing tees and
forged steel straight tee/bushing combinations. Allows for
field installation in pipelines from 1/2" to 2" diameter.
A table with approximate actuation and deactivation values
is provided on the "Specifications" page.
