WFM Water meter - 1

Water Meter Contactors WFM Series 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. These meters are available with either a two-wire reed switch, or a solid state, threewire Hall effect sensor. The Hall effect sensor provides long lasting service and requires power. The reed switch provides a dry contact closure and does not require power. The WFM meters are typically used in cold water applications with cooling tower or boiler conductivity controllers and metering pumps for chemical feed. They do not have NSF Standard 61 certification for drinking water applications. Simple and dependable multi-jet design. Available in 3/4”, 1”, 1½” and 2” NPT sizes for flow rates from 0.22 to 132 GPM. A wide range of pulse rates for a variety of applications. Reed switch or Hall effect sensor options. * Not approved for drinking water. PULSE RATES AVAILABLE 1” B (Body with couplings)
