For example:

A flowmeter has a K-factor 2053.57 imp/Gal and the display should read in Gal/Min. with accuracy to
three decimal places.

KFR = 6000/2053.57 = 2.921741 for GPM

Round off 2.921741 to three decimal places and enter 2.922 for KFR.

GATE A B (Gate Time)

This variable

sets the sample time on the incoming frequency for the RATE A GT and RATE B GT (Gate Time)
displays

is programmed in tenths of a second (the allowable range is from .01 to 600 seconds)

affects the update of the display and analog output (FEM-03A, -03A2, or -03Ax only)

is useful in stabilizing the display and output when dealing with slight variations in flow

default is 002.00 seconds

When entering or editing the value, the digit being edited blinks starting with the left-most digit. Select
the digit to edit using SEL. Press and hold the UP or DN key to increase or decrease the value. When the
desired value displays, press the ENT key to store and advance to the next variable.

SAMPLE A or SAMPLE B

This variable

determines the amount of digital filtering performed on the incoming frequency for the RATE A
PL or RATE B PL (Pulse Length) display

affects the update of the display and analog output (FEM-03A, -03A2, or -03Ax only) and can be
used as a filter to stabilize the display and output

Flowable range is from 0 to 253 with 0 providing the least level of filtering and 253 the maximum;
default is 010.

When entering or editing the value, the digit blinks starting with the left-most digit. Select the digit to
edit using SEL. Press and hold the UP or DN key to increase or decrease the value. When the desired
value displays, press ENT to store and advance to the next variable.
