    The user can select from square wave outputs of 24, 50, 100, 200, 300, 500, 600 or 1000 pulses per revolution, or two-phase outputs of 12, 25, 50, 100, 150, 250, 300 or 500 pulses per revolution (on each phase). 286-300-350 © 2002, Max Machinery, Inc.

  • Page 4: Mechanical Installation

    It is a good idea to locate the transmitter away from hot spots such as steam pipes, ovens and heaters. The electronics of the 286 Series Transmitters are rated for operation up to 80° C (175° F). Because some heat travels from the flow meter to the transmitter electrical enclosure, the temperature of the electronics is a function of both the ambient and the flow meter temperature.

  • Page 13: K-Factors

    K-factors represent the number of pulses the transmitter outputs per unit volume of fluid passing through the flow meter. This number is dependent on the flow meter and the transmitter resolution setting (switch S3). Max Machinery indicators can be adjusted to display the desired units (ccs, lbs, gallons, quarts, etc.) by using the K-factor.
