Flow Tab
Flow Rate Units are selected from the pull-down lists. Select an
appropriate rate unit and time from the two lists.
Totalizer Units are selected from the pull-down lists. Select an
appropriate totalizer unit and totalizer exponent. The totalizer
exponents are in scientific notation and permit the eight digit
totalizer to accumulate large values before the totalizer “rolls over”
and starts again at zero. Table 4.1 on page 4.6 illustrates the
scientific notation values and their respective decimal equivalents.
MIN Flow is used by the TFX to establish filter settings in its
operating system. Enter a flow rate that is the minimum flow rate
anticipated within the system. For unidirectional systems, this value
is typically zero. For bi-directional systems this value is set to a
negative number that is equal to the maximum negative flow rate
that is anticipated within the system.
MAX Flow is used by the TFX to establish filter settings in its
operating system. Enter a flow rate that is the maximum, positive
flow rate anticipated within the system.
