weber Sensors Inc., of Woodtsock, Ga., introduces the revolutionary CoolGuard. This first-of-a-kind flow captor is two sensors in one. It monitors the flow rate as well as the temperature of the flowing medium, and provides a solid-state switch if flow is lost or temperature is exceeded. It has no moving parts and is the ideal replacement for mechanical flow switches. It won’t foul, stick, wear out, or be damaged by excessive flow rates. It mounts horizontally or vertically with no effect on the switching point.
