Iwaki America and Walchem, IWAKI America Inc Water Meter Contactor WFM071

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. For pulse output, one of the pointers is replaced by a magnet, which is detected by an encapsulated sensor attached to the outside of the lens. Pulse rate is determined by the dial on which the magnet is placed and by the number of sensors (single or double). Changing the pulse rate requires no special tools and can be done in the field. The WFM Series uses the widely recognized multi-jet principle, which has been accepted as an international standard for many years.
