WFM-SERIES W F M - S E R I E S P u l se M E T E R i n str u c ti o n s Pulse METER instructions
GENERAL INFORMATION, INSTALLATION and MAINTENANCE GENERAL INFORMATION SPECIFICATIONS WFM-Series meters use the internationally-accepted multi-jet principle. A gear train drives the register totalizer dials. For pulse output, one of the pointers is replaced by a magnet arm, which is detected by an encapsulated sensor attached to the outside of the lens.
CHANGING PULSE RATES Setting Your Pulse Rate. The pulse rate is determined by which sensor was ordered from the factor y (single reed switch, dual reed switch, or single Hall-effect) and by the dial on which the magnet pointer is located. The pointer is set at the factory, but can be changed in the field as follows.
