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.
Claims16
A fluid flow sensing device comprising:
- a stem portion;
- a paddle portion;
- a pivot disposed between the stem portion and the paddle portion;
- a magnetic opener configured to bias the paddle portion away from the stem portion into an “off” position;
- and
- a sensing device associated with the stem portion and the paddle portion which, upon a sufficient pressure impending on the paddle portion by a flowing fluid to overcome the magnetic opener causing the paddle portion to pivot to an “on” position towards the stem portion, creates an electronic signal indicating detection of fluid flow above a predetermined threshold.
