Flow meter system suitable for use in combination with a water treatment plant

A flowmeter system useable with a water treatment device includes a turbine housing (144) having a channel (118) for channeling water past a flow reactive turbine device (148), positioned for measuring the volume of flow in a channel (118), and a signal generating member (90) positioned on the flow reactive device (148). A sensor (182) is positioned proximately to the flow reactive device (148) and is sensitive to the proximity of the signal generating member (90). The sensor (182) is capable of sensing the flow volume sensed by the flow reactive device (148) and communicates electrical signals representative thereof.
