Honeywell WFS Water Flow Switch
Construction:
WFS series flow switch is used for operational control aiming to prevent control failure which may cause damage to equipment and hazard to operators. It improves safety by setting control limit, alarm and report to monitoring system.
WFS series flow switch can be applied to water or other liquid which will not corrode copper.
WFS series flow switch provides single pole double throw (SPDT) output with high accuracy and reliability. When the liquid flow rate reaches above or below the set point, one circuit will be closed and the other will be open. It is typically used in situation involving interlocking or close-off protection.
WFS flow switch can be mounted horizontally or vertically on pipe where there needs a clearance of 5 times the pipe diameter on both ends of the flow switch so to maintain a laminar flow for accurate operation. It can be mounted outdoors with rain shelter.
