Seametrics FT96M - Manual

FT96M Flow Computer Instructions
General Information
The SeaMetrics FT96 is a battery-powered digital indicator which converts pulses from the flow
sensor into rate/total information. Power for this unit is provided by two lithium C-size batteries
located inside the housing. Pulse output for telemetry or pump control is a standard feature. The
pulse output is an Opto-isolated open collector transistor.
Display
The rate display has 4.5 digits and updates once every two seconds. The descriptors on the rate
display are : /SEC, /MIN, /HR. The totalizer display has 8 digits and it's descriptors are : GAL, LIT,
FT3, M3, and "blank". The other display is a warning display, which has a low battery warning
indicator.
Settings
This unit will normally be installed and programmed with the necessary settings at the factory. If it
is necessary to make any changes, follow these procedures.
Keys. Press the M key to enter the programming menu. Press it again to advance to the next menu
item. Use the up arrow to increase the digit displayed, and the horizontal arrow to advance to the
next digit. When the desired number is displayed, use the E key to enter it.
Reset. The first menu item is labelled "Clr tot". Pressing the E key when this is displayed will reset
the total to zero. Press M to go to the next item if totalizer reset is not desired.
Set K-Factor. The K-factor is the number of pulses per unit volume which the meter or flow
sensor provides. For some SeaMetrics flow sensors it is marked on the unit itself or on the sensor
fitting, for others it must be taken from a chart in the instruction manual.
The K-Factor range for the FT96 is 0.001 to 59999.
This number is preprogrammed into the FT96. If it is necessary to change it, follow these steps:
1.Skip the menu item "FAC mul" (factor multi-plier).
2.The next item is "Fdec" (factor decimal). In the unlikely event that the decimal point must be
changed, step it to the desired location and press E.
3.Advance to "FAC" (factor). Enter the desired K-factor.
Totalizer Decimal Point. The next item is "tdEC" (totalizer decimal). This is the location for the
decimal point on the totalizer display. Step to the desired location and enter.
