Section 4 MC-III™ EXP Flow Analyzer
Turbine Input
The Turbine Input screen (Figure 4.21) allows users to configure the displays for volume and rate, select the
type of input to be used (turbine input or pulse input), determine cut-off thresholds for measuring flow, and
determine the display update frequency.

Volume Display
The Volume display can be configured to display totals in one of five preprogrammed engineering units or in a
user-defined unit (for use with a calculated divisor).
Important: If volume is to be measured in user-defined units, the K-Factor unit must also be
entered as “pulses per unit.” For more information, see
Entering a Calculated Divisor, page
32 .
To display the volume in multiples of 1,000 units, check the “Multiplier” checkbox.
The device will display volumes up to 10,000,000, however, a maximum of eight digits (including decimals)
are visible at a time. Therefore, once the volume (including decimals) grows beyond eight digits, digits on
the leading edge of the value will be hidden from view. To increase visibility of the whole numbers, move the
decimal one or more places to the right.
Important: Before enabling or disabling the “× 1000” unit option for displaying flow totals, clear
the total display to zero. If the total is not cleared, the accumulated total displayed will
represent a combination of two different units and will not provide an accurate flow read
