Abstract
A fluid flow sensing device having at least a stem and a paddle portion which is pivotally disposed with the stem, and a magnetic opener which biases the paddle away from the stem to into an 'off' position. Upon sufficient pressure impending on the paddle by flowing fluid to overcome the force of the magnetic opener, the paddle pivots towards the stem to an “on” position, which is sensed by a device such as a Hall effect sensor, reed switch, or optical sensor.
