Dwyer Instruments V10-SS Flotect Mini Flow Switch 303 SS 1/2" NPT

The Dwyer Instruments V10-SS Flotect Series V10 mini-size flow switch (also called a mini flow switch or vane flow switch) proves the presence or absence of gas or liquid flow in a system. It has a 303 stainless steel body and a 1/2" male NPT process connection. It is used to monitor unattended equipment and help protect it from damage caused by low or no flow.

Key Features:

• Rugged, magnetically actuated design with a hermetically sealed SPST reed switch
• Field-adjustable between normally open (NO) and normally closed (NC) by loosening two screws, with no change to the electrical connection
• 303 stainless steel body rated to 2000 psig (138 bar)
• 301 stainless steel vane, trimmable to the pipe size. A removable laminated template is provided.
• Fits field installations in 1/2" to 2" diameter pipelines
• The switch housing sits outside the process media, so the switch can be changed over or serviced without interrupting flow
• Weatherproof enclosure, NEMA 4X (IP66)

Specifications:

• Service: compatible gases or liquids
• Wetted materials: 303 SS body, 301 SS vane, ceramic 8 magnet
