MC-III™ Panel Mount Flow Analyzer Section 1
Section 1—Introduction
The NuFlo™ MC-III™ Panel Mount Flow Analyzer (Figure 1.1) packs a full spectrum of gas and liquid
measurement functionality, high-speed performance, and log archive and retrieval capabilities in an easy-
to-use totalizer. Commonly used operations can be accessed from the six-button keypad on the front of the
instrument or from the dynamic interface software, allowing you to calibrate and congure the unit quickly
and easily. The device installs easily in a ¼ DIN panel opening measuring 3.62 in. square.
Operation
The MC-III Panel Mount calculates and displays instantaneous ow rates and accumulated totals based on
a turbine ow meter input signal. The MC-III’s microprocessor circuitry counts the pulses generated by a
companion ow meter, converts that data into volume and rate values in accordance with calibration settings,
and displays the totalized data on a two-line liquid crystal display (LCD). The eight-digit top readout indicates
total ow volume; the six-digit bottom readout indicates ow rate.
With the press of a single key, totals are saved to nonvolatile memory, minimizing the risk of data loss even if
a power outage occurs.
Up to 384 daily logs, 768 hourly logs, and 345 event logs can be archived and accessed quickly on demand.
Offering a variety of user-congurable display options, input and output options, RS-485 Modbus®
compatibility, ow logging, and turbine ow meter linearization, the MC-III Panel Mount is one of the most
versatile totalizers on the market. For specications, see Table 1.1, page 8.

Key Product Features
This section presents an overview of key features of the MC-III Panel Mount. Many of these features are
discussed in more detail in Sections 3 and 4 (conguration procedures) and Section 5 (ow log archival).
Key features discussed here include:
• LCD display
• keypad
• interface software
• power supply
• calibration options

Section 1 MC-III™ Panel Mount Flow Analyzer
• input options
• output options
• ow log archival
• password-protected security
LCD Display
The liquid crystal display (Figure 1.2, page 11) 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 Panel Mount, 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
gallons per minute). Also, the volume unit used for the ow rate can be different from the volume unit used to
read Total volume. The unit of measure for the Rate readout and the decimal point position are selected by the
operator during calibration.
The daily index (Day) display is a two-digit number for selecting a daily archive log for viewing. The number
shown here represents the number of days that have passed since the log was saved. For example, an entry of
01 would yield yesterday’s log. An entry of 05 would yield the log generated 5 days ago. Up to 99 consecutive
daily logs can be viewed using the keypad. In addition, up to 384 daily logs, 768 hourly logs, and 345 event
logs can be viewed through the interface software.
The LCD contrast can be adjusted with the interface software (see Section 4).
Keypad
The six-button keypad allows users to perform a basic conguration of the instrument. Figure 1.3, page
11, summarizes the functions that can be accessed with each button. Most parameters can be congured in
seconds by selecting one of the three menu keys (K-Factor, Output, or Display), navigating settings with the
arrow buttons, and saving the selections with the Enter key.
Section 3 contains procedures for conguring the MC-III Panel Mount using the keypad. Icons of the six
buttons provide a pictorial reference to help guide users through each step of conguration.
Important: Some conguration parameters are accessible only through the interface software. See
Section 4 for instructions on conguring the instrument using the software.

Interface Software
Developed within the familiar Windows environment, the MC-III interface software is an intuitive and
easy-to-use application that provides access to all controls for setting up and operating the instrument. The
interface tailors the controls to the user’s needs, providing three options for conguring the instrument:
• a “Conguration Wizard,” which steps through the most common conguration tasks
• individual conguration menus for accessing specic settings
• an advanced menu that gives host programmers access to Modbus®registers

12
Section 1 MC-III™ Panel Mount Flow Analyzer
For instructions on installing the interface software and entering conguration parameters via the interface
software, see Section 4.
Power Supply
The MC-III Panel Mount is shipped with a lithium battery. Alternately, the MC-III Panel Mount may be
powered by an external power source; in this case, the lithium battery provides a backup power supply,
signicantly extending battery service life. Low-power microprocessor technology enables the MC-III Panel
Mount to operate approximately 2 years on a single lithium battery.
External Power Supply. The device will automatically switch to battery power when external power is lost. It
is recommended that the external power supply be an approved ELV source, insulated from the AC main by
double/reinforced insulation per CSA C22.2 No. 61010-1-04 / UL61010-1 – 2nd Edition.
Wiring diagrams for connecting an external power supply are provided in Section 2.
Multipoint Linearization
The MC-III interface software supports up to 12 calibration points in addition to single-point calibration based
on the K-factor provided with the turbine ow meter. See K-Factor Type, page 59 for more information.
Gas Volume Correction
Gas turbine meters are calibrated in actual cubic feet (ACF), and measure gas in actual cubic feet. In some
applications, a user may benet from referencing gas measurements back to standard conditions by measuring
in terms of standard cubic feet (SCF). The MC-III Panel Mount makes this process quick and easy, by using
xed average values for the owing gas temperature and owing gas pressure. See Gas Volume Correction
(Supercompressibility Calculation), page 61 for more information.
Input Options
The ow meter signal can be obtained from a magnetic pickup or a pre-amplier device. The sensitivity of
the ow meter input may be adjusted with the instrument keypad or the interface software. See Section 2 for
wiring diagrams. See Sections 3 and 4 for conguration procedures.
Output Options
The MC-III Panel Mount standard circuitry provides:
• a scaled pulse output representing an increment in volume for each pulse
• a loop-powered 4-20 mA output representing the ow rate
• a ow meter frequency output for use with remote equipment to derive ow rate and volume
• an RS-485 output for communication with interface software or other telemetry equipment
When the 4-20 mA rate output feature is used, the MC-III Panel Mount is powered by the current loop, and
the lithium battery is used as a backup supply.
The pulse output and 4-20 mA output features should be turned off when not required for reduced current
consumption. See Section 2 for wiring diagrams. See Sections 3 and 4 for conguration procedures.
Flow Log Archival
The MC-III Panel Mount saves up to 384 daily logs and 768 hourly logs in nonvolatile memory. By
connecting with the interface software, users can download the logs for viewing and/or printing in tabular
format or in a trend chart.
Users can also export daily and hourly logs to a spreadsheet. For more information, see Section 5.

13
MC-III™ Panel Mount Flow Analyzer Section 1
Event Log Archival
The MC-III Panel Mount saves up to 345 user event logs. Event logs are generated to track user changes such
as
K-factor changes, input setting changes, power-on reset and “watch-dog” reset, ow cut-off and frequency
cut-off.
By connecting with the interface software, users can download the logs for viewing and/or printing in tabular
format. In addition to showing old and new values, each event log is time-stamped, and includes the register
associated with the change. For more information, see Section 5.
Password-Protected Security
A keypad security access code prevents unauthorized personnel from altering the calibration or accumulated
volume data in the instrument. The security feature may be disabled if this protection is not required.
Password-protected security access is enabled using the interface software. When this feature is enabled,
the user will be prompted for a password when attempting to enter any menu from the keypad. For more
information, see Security Setup, page 53.
Commonly Used Functions
While the functions of the MC-III Panel Mount are too numerous to mention, some of the most commonly
used functions are detailed in this section. They include:
• reading the rate and accumulated total
• saving totals to memory
• resetting the total
• viewing daily and hourly logs
• saving and uploading conguration les
• exporting log data to spreadsheet
• saving log data in a report
Reading Totals
Current totals can be viewed from the LCD on the front of the MC-III Panel Mount or from the interface
software (MC-III Main screen). The software calculates the ow total and updates the LCD display every 4
seconds, by default. The user can adjust the calculation period with the interface software. See Calculation
Period, page 58, for more information.
Saving Totals to Memory
Hourly and daily totals are automatically saved to nonvolatile memory. A user may also save an accumulated
total at any time by pressing ENTER (SAVE) on the keypad. In the event of a power failure, the last saved
total will be displayed on the LCD when power is restored.
Important: Always save the accumulated total before replacing batteries.
Resetting the Total
Totals can be reset to zero using the keypad, the interface software, or a pulse from an external device.
• To reset the total with the keypad, press LEFT ARROW (LOG) and ENTER (SAVE) keys simultaneously.

Viewing Daily and Hourly Logs
Each day, as the user-dened contract hour passes, a daily ow total is saved to nonvolatile memory. Hourly
logs are also automatically saved. A total of 384 daily logs and 768 hourly logs are accessible for viewing and
exporting using the interface software. See Section 5 for details.
Up to 99 daily ow log totals can be viewed from the LCD. Hourly ow log totals are accessible only through
the interface software.
To view daily ow totals from the LCD, perform the following steps:
1. Press the LEFT ARROW (LOG) key on the keypad. The words “Daily Volume Archive” will scroll across
the bottom of the LCD and the day index will display “01.” The daily ow total recorded at the last con-
tract hour will appear at the top of the LCD.
The index number represents the number of days previous to the current date. For example, yesterday’s
totals are read by entering an index of “01”; totals from two days previous are read by entering “02.”
2. Press UP ARROW (TEST) to increment the index (01, 02, 03...); press LEFT ARROW (LOG) to decre-
ment the index (01, 99, 98...).
3. Press Enter (Save) to exit the Daily Volume Archive menu. (After 2 minutes of inactivity, the Daily Vol-
ume Archive menu will time out and the total readout will be restored automatically.)
Saving and Uploading Conguration Files
The MC-III interface software allows users to save an unlimited number of conguration les to their
computer. In the event that a conguration setting gets changed unintentionally or a user simply wants to
restore the settings he used previously, the user can upload the conguration le and resume operation within
minutes. The upload function also allows a conguration le to be loaded quickly into multiple devices. The
default directory for saving conguration les is C:\NuFlo log data\MC-III. However, users can specify a
different location, if desired.
For complete information, see Saving and Uploading Conguration Files, page 69.
Exporting Log Data
Flow logs and event logs can be directly exported to an .xls or .csv le. For complete information, see
Exporting Flow Logs, page 81, and Exporting Event Logs, page 84. The default directory for exported
logs is C:\NuFlo log data\MC-III. However, users can specify a different location, if desired.
Saving Log Data in a Report
Flow logs can be saved in a report format that can be loaded back into the software for viewing or printing
at a later time. For complete information, see Printing/Saving a Report, page 77. The default directory for
log reports is C:\NuFlo log data\MC-III\<WELL NAME>. However, users can specify a different location, if
desired.

Section 2—Installation
The MC-III™ Panel Mount is fully assembled at the time of shipment and ready for installation. Before
attempting to install the MC-III Panel Mount, make sure the ow meter and magnetic pickup are installed.
Flow Meter/Magnetic Pickup Installation
Install the ow meter and magnetic pickup as follows:
1. Install the turbine ow meter in the ow line.
2. Lightly grease the threads on both ends of the magnetic pickup, taking care to keep grease off of the con-
nector contacts. If the connector is plastic, apply grease only to the end that threads into the meter.
3. Install the magnetic pickup in the ow meter.
4. After the ow meter and magnetic pickup are installed in the ow line, mount the MC-III Panel Mount
ow analyzer as described below.
MC-III Installation
The MC-III mounts in a standard ¼ DIN square opening (3.62” X 3.62”) in a vertical panel. To install,
reference the dimensions in Figure 2.1, page 16.
Studs (#6-32 X ¾”) and nuts (#6-32) with integral lockwasher are supplied for mounting the instrument.
Additional customer-provided mounting fasteners such as washers or clamps are required to secure the device
from the back side of the panel. The style will vary with the installation and the thickness of the panel used.

Field Wiring Connections
All eld wiring connects to the circuit assembly mounted on the back side of the switchplate.
Wiring Procedure
To wire the MC-III Panel Mount for operation, complete the following eld connections:
1. Connect the lithium battery connector to the J1 receptacle on the circuit assembly.
2. Connect wiring for external power, if appropriate. See Figure 2.2, page 18.
3. Connect the ow meter or pulse input wiring to terminal block TB1. See Figure 2.3 or Figure 2.4, page
19.
4. Connect wiring for the remote reset input to terminal block TB1, if appropriate. See Figure 2.5 or Figure
2.6, page 20.
5. Connect wiring for output signals, if appropriate. See Figure 2.7, page 21, through Figure 2.12, page
24.
6. Recalibrate the MC-III Panel Mount (if necessary).
7. If external and internal power supplies were removed, reset the clock to ensure that the time stamps in the
log data are accurate. The clock is reset using the MC-III interface software. See Time/Date Synchroniza-
tion, page 52.

Power Supply Wiring
Internal Power Supply
The MC-III Panel Mount is shipped with a 3.6-V lithium battery.
Low-power microprocessor technology enables the MC-III Panel Mount analyzer to operate approximately
2 years on a single lithium battery. The lithium battery is strongly recommended for use in extreme
temperatures (below -20°C).
Users can power the instrument from an external power supply or a 4-20 mA current loop, and use the lithium
as a backup power supply. The use of an alternate power source extends battery life and helps ensure that
timekeeping and volume accumulation will not be interrupted during a power failure.
External Power Supply
The MC-III Panel Mount can be connected to a remote power supply by a two-conductor cable (Figure 2.2).
The power supply and cable must be capable of supplying 6 to 30 VDC @ 10 mA. This capability is available
only if the 4-20 mA rate output is not used.
External Power Supply. The device will automatically switch to battery power when external power is lost. It
is recommended that the external power supply be an approved ELV source, insulated from the AC main by
double/reinforced insulation per CSA C22.2 No. 61010-1-04 / UL61010-1 – 2nd Edition.
Caution: When using the amp & square output with the external power supply, make sure the
power supplies for both features share a common negative (-) terminal or that they are
totally isolated from each other, since both share a common negative (-) connection.
