ABSTRACT:
A totalization meter system for a water treatment device, the device having an inlet aperture and an outlet aperture, and a channel for channeling water between the inlet and outlet apertures. A flow reactive device is positioned in the channel and is exposed to the flowing water, and a signal generating member is positioned on the flow reactive device. A switch is positioned proximately to the flow reactive device, and is sensitive to the proximity of the signal generating member. The switch is able to communicate electric signals indicative of the motion of the signal generating member. A resettable processor having a performance threshold programmed therein and an output device is included. The microcontroller is in electrical communication with the switch for receiving electrical signals from the switch. The switch is capable of sensing the characteristics of the flow reactive device and communicates electrical signals representative of the characteristics to the microcontroller. The microcontroller interprets the signals as a first performance data. The microcontroller compares the first performance data against the respective performance threshold in the microcontroller to determine if the performance threshold has been surpassed, and if surpassed actuates the output device.
