Menu Navigation
The left/right keys are used to move through the menus
and position the cursor during data entry. The up arrow is
used to scroll through the available values that are to be
entered. (examples: numerical values for K factor entry or
selection of units from the available options) The enter key
(represented on the keypad by the check mark) is used to
save selected entries and in conjunction with the exit tab to
move between menu screens. As one navigates the menus
the current parameter setting is shown and instructions are
displayed for how to change the selected parameter.
MAIN MENU
All menu screens consist of two rows of tabs surrounding a
dialog box that lets you view and change setup parameters.
SET K
View or change the K factor. The K factor is the number of
pulses the flow sensor provides for every gallon of flow.
(Note that the decimal is fixed at three places. If you only
have two decimal places for your K-factor, enter a zero for
the third digit. If unable to set K-factor, the unit is "locked"
to prevent tampering. Please contact your distributor for
assistance.)

K-Factor
At a minimum, every FT430/440/450 flow computer must
be programmed with the “K-factor”. (This is the number of
pulses that the meter produces per gallon of flow.) If you
wish to read in units other than gallons, see below.
The K-factor on any Seametrics flow sensor fitting or in-
line meter can be found on the model-serial label. The line
reading K = xxxx gives the desired number. For depth-
adjustable sensors (110, 210, 150, 250 models), use the
calculator on our website.
(Refer to the appropriate instruction manuals for iMAG
4700, AG3000 or WMP pulse settings.)
Note: The K-factor on all FT430/440/450 flow computers is
expressed in
pulses per gallon
of flow regardless of rate or
total units.
