摘要: A water flow detector has a spring driven mechanical timer responsive to the movement of a lever. The lever is connected to a paddle. The paddle is responsive to the flow of water in a pipe. The detector via the spring driven timer responds to the flow of water in the pipe after a predetermined delay.

摘要: A control unit can be in communication with a plurality of displaced duct sensors. Sensors can be placed in supply and return ducts of an HVAC-type fluid delivery system. The unit can communicate status information as well as sensor sensitivity or other parameter values, on a per sensor basis, to a remote accessory unit via a communication protocol. The units can communicate via a wired or wireless medium.
