Abstract
A fluid flow monitoring system including one or more fluid flow dispensing valves each including a piston. Fluid flow sensors are associated with the fluid flow dispensing valves for measuring fluid flow. The fluid flow sensors include a housing with a magnet positioned therein and a piston follower is coupled to the magnet. The piston follower includes a shoulder portion positioned within the housing. A spring is operative to bias the magnet and piston follower towards the piston during operation so that piston movement is transmitted to the magnet. The housing includes a retainer portion disposed on the housing that confronts the shoulder portion of the piston follower whereby the magnet, piston follower, and spring are retained within the housing. The system also includes a fluid flow monitor that includes a microprocessor programmed to convert cycle signals from the sensors to fluid flow information.
