Key Product Features
This section presents an overview of key features of the MC-III EXP. Many of these features are discussed in
more detail in Section 3, page 35, and Section 4, page 45 (conguration procedures) and Section 5, page 79 (ow
log archival).
Key features discussed here include:
• LCD display
• keypad
• interface software
• power supply
• calibration options
• input options
• output options
• ow log archival
• password-protected security
LCD Display
The liquid crystal display (Figure 1.4, page 12) provides a simultaneous indication of accumulated total (top
readout) and ow rate (bottom readout). The eight-digit total display uses 7-segment characters to form
numbers and letters, which results in a combination of uppercase and lowercase letters. The six-digit ow rate
display uses 11-segment characters to form numbers and letters for improved readability. When the keypad
is used to calibrate the MC-III EXP, the name of the menu option selected appears in the lower (rate) display,
and settings are entered in the top (total) display.
Flow volume can be measured in barrels, gallons, liters, cubic meters, cubic feet, standard cubic feet or other
user-dened units. A multiplication factor is also available for indicating ow volume in terms of 1,000 units.
The unit of measure for the Total readout and the decimal point position are selected by the operator during
calibration. If a user-dened unit is used, none of the preprogrammed volume units will be visible on the
display during operation.
Flow rate can be measured in a wide variety of preprogrammed units, or other user-dened units. The ow
rate unit of measure is selected in two steps: (1) a volume unit is chosen and (2) a time-base unit (per day, per
hour, per minute, or per second) is chosen. Users can choose any combination of preprogrammed volume and
time units in establishing the ow rate engineering unit (for example, gallons per hour, gallons per day, or
