Blade-Style Flow Switch
Blade Style Flow Switch
Since the mid 1980’s these blade-style flow switches has been used by some of the largest companies in the fluid control industries as well as Pool & Spa. It has several factory adjustable parameters that provide the flexibility to meet the requirements of almost any application.
The blade-style switch verifies fluid flow, typically in conjunction with another device. For example in a chiller it prevents the system from freezing, and in most of swimming pool salt chlorine generators it has been used to verify sufficient flow before the generator is energized. In a spa or hot tub it ensures sufficient flow to prevent the water heater from a meltdown, and at home it turns on the water disinfection system when someone is getting a glass of water.
Typical Working Fluids
For use in a broad spectrum of industrial fluids, such as:
- Cooling Tower Water
- Water (saltwater, pure, tap, etc.)
- Glycol Solutions Lubricating Oils
- Mild Acids Gasoline
- Plating Solutions JP-4
– Max. flow may be five times normal flow.
– Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element.
– Very low pressure drop – typically less than 1.0 psig at normal flow rate.
– Small size and low profile provides easy mounting in crowded installations.
– Power the driving coil of small ice cube relays as well as some 30A power relays.
– Switches 5VDC to 240VAC.
– Switch employs magnetic coupling.
– Can be used in ¾ inch to 6 inch pipe
