Dwyer V6 FLOTECT Mini Flow Switch Liquid Gas Air Flow Monitoring

Product Specification

The extremely compact Flotect® V6 flow switch is designed to monitor the flow rate of liquids, gases or air. It operates magnetically and has no mechanical connections for easy and reliable operation.
The lower body has vanes and a magnet that operates the switch by controlling the magnet in the upper compartment. In most applications the switch is normally open and the fluid in the pipe makes the vane
The leaf spring is compressed, and when the flow rate decreases, the spring pushes the leaf back into place, triggering the switch to alarm or close. Optional tee to easily install the flow switch, the tee is safe
Fitted pipe sizes are 1/2" - 2", and when sleeved, are well suited for 1/4" and 3/8" pipe.

feature
• Leak-proof lower body machined from bar stock
• Optional for tee mount with calibrated vanes or field adjustable vanes
• 24/7 protection
• Explosion-proof (listed in Specifications)
• Easy replacement of electrical components without disassembly to ensure uninterrupted process
• High pressures up to 1000 psig (69 bar) with brass body and 2000 psig (138 bar) with 316 stainless steel body (see Specifications)
• Low flow models have on-site adjustment of the setpoint
• Easy to install, just insert the tee into the pipeline and connect the power
