F61 Series
Flow Switch (Low Flow Rate - SPDT)
Description
For use on liquid lines using water, ethylene glycol
solutions, or other liquids not corrosive to the brass or phosphor bronze parts.
The SPDT contact switch is activated by a low flow rate; however, it has a large
flow capacity with a minimum pressure drop.
Applications
- water purification and treatment systems
- booster pumps
- fast shutdown on high input boilers to guard against
circulation failure
- cooling systems for electronic tubes, bearings, and
compressors
