A fluid flow rate sensor, which may also be the basis of a valve for a fire suppression system, uses a sensing arm to convey motion of an obturation body or a valve closing member to a sensor system which evaluates the motion and generates a calibrated measure of the flow rate and/or an alarm signal in response if warranted. The obturation body and the valve closing member are capable of both rotation and translational motion, both of which are sensed using the sensing arm. The sensor system is isolated from the fluid within the valve.
A flow rate sensor, said flow rate sensor comprising:
A valve, said valve comprising:
A method of detecting fluid flow through a valve comprising a valve housing, said valve housing defining a seat, a valve closing member positioned within said valve housing and movable between a closed position sealingly engaged with said seat and preventing said fluid flow, and an open position permitting said fluid flow, said method comprising using a sensing arm mounted on said housing and engaged with said valve closing member to sense motion of said valve closing member between said closed position and said open position.
A fire suppression sprinkler system connectable to a water supply, said sprinkler system comprising:
