The WCT and WBL controllers are capable of powering a hall effect style water meter sensor. Options for the WFP Series flowmeter include a low frequency (less than 10 Hz) contacting head meter or a high frequency (10-300 Hz) paddlewheel. Paddlewheel sensors cost less than contacting head meters in pipe sizes greater than two-inch diameter. The solid-state hall effect sensors last longer than the mechanical reed switch sensors. The series is designed for chemical proportioning applications and readily interfaces with the company’s WebMaster® series controllers. WFP flowmeters are impeller-type insertion meters designed for use in pipe sizes of ½-8 inches. High quality jewel bearings and nickel-bound tungsten carbide shaft are used, creating superior low-flow performance.
