WFM Flowmeters utilize the multi-jet principle to provide dependable, accurate performance. They are available in ¾, 1, 1½ and 2” NPT pipe sizes. A pulse output provides a signal to a controller or to a metering pump for proportional chemical feed. WFM Series water meters have earned a reputation for design simplicity, wide range of applications and accuracy in low-quality water. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials.
