Dwyer V8 flow switch is a vane operated flow switch. It is a low cost, simple design for use with air flow and liquid flow applications. Materials are generally plastic (Polyphenylene Sulfide, PPS) with 316SS/Inconel spring and pin arrangement and Ceramic 8 magnet. Dwyer V8 flow switch is a low cost, economic design suitable for many HVAC applications. The vane is field trimmable, these units are suitable for stocking and can be adapted to suit application on site. Options are limited to enclosure material (or without) and gold plated contacts. Gold plated contacts are appropriate for dry circuits. This is where the switching current is so small that it cannot deal with any slight of oxidation of the switch contact.
The Dwyer V8 Flow Switch is designed for horizontal flow applications. It can be used in vertical lines with an upwards flowrate but not downwards flow (as the vane itself will naturally drop).
