See Sections 3 and 4 for instructions. 1. Make sure the flowmeter and magnetic pickup are properly installed as follows: a. Install the turbine flowmeter in the flow line. b.
Section 2 MC-III™ EXP Flow Analyzer Field Wiring The MC-III EXP supports connections for the following: internal power (battery), external power, turbine flowmeter input, pulse input, remote reset input, pulse output, 4 to 20 mA output, flowmeter frequency (amp & square) output, and RS-485 output. Wiring diagrams for each connection are provided below.
MC-III™ EXP Flow Analyzer Section 2 Internal Power Supply The MC-III EXP is shipped with one of three internal power supplies: • a CSA-approved 3.6V lithium battery • an ATEX-approved 3.6V lithium battery • a shrink-wrapped alkaline battery pack containing three C-size industrial-grade batteries (available only with CSA-approved devices) Low-power microprocessor technology enables the MC-III EXP analyzer to operate approximately 2 years on a single lithium battery.
Section 2 MC-III™ EXP Flow Analyzer Turbine Flowmeter (TFM) Input 6-3 0V DC BATTERY The TFM input provides the turbine flowmeter input signal generated by a magnetic pickup, enabling the MCIII EXP to calculate and display instantaneous flow rates and accumulated totals. TB A&S 3 EXT POWER GND J1 TFM B TURBINE MAGNETIC PICKUP VMAX = 3.9 V RESET INPUT A PULSE INPUT TB1 RESET SWITCH J2 Figure 2.
MC-III™ EXP Flow Analyzer Section 2 Remote Reset Input The remote reset input allows the operator to reset the accumulated volume on the MC-III EXP to zero without opening the enclosure. This input is optically isolated. The input is shown connected in two ways, with a power supply and switch in a safe area (Figure 2.11), and with a pulse generator in a safe area (Figure 2.12). The remote reset input can also be controlled with an optional explosion-proof switch mounted in the top of the enclosure.
Section 2 MC-III™ EXP Flow Analyzer Pulse Output The pulse output is a solid-state relay. Each pulse represents a user-defined volume. Because the circuit is isolated, it can be used in conjunction with any other feature on the MC-III EXP. A two-conductor cable from the MC-III EXP to the remote location is required (Figure 2.13). The maximum current rating of the pulse output circuit is 60 mA at 30 VDC. A Zener diode (Part No. 1.5KE56CA) must be installed for CE approval.
MC-III™ EXP Flow Analyzer Section 2 Analog (4-20 mA) Rate Output The 4-20 mA rate output provides a linear current output that represents flow rate. This output requires a twoconductor cable connected to an 8 to 30 VDC power supply (voltage required is dependent on loop resistance) and a current readout device located in the remote location. The 4-20 mA rate output current loop also powers the MC-III EXP.
Section 2 MC-III™ EXP Flow Analyzer Flowmeter Frequency Output The flowmeter frequency (amp & square) output provides an open drain transistor output at the turbine meter frequency, which may be used to provide flow rate and/or total information to peripheral equipment. The output requires a two-conductor cable from the MC-III EXP to the remote frequency readout device requiring 50 mA or less and a 5 to 30 VDC power supply (Figure 2.15).
MC-III™ EXP Flow Analyzer Section 2 RS-485 Output The RS-485 output is required for communication with the interface software. Wiring diagrams are provided for a permanent connection (Figure 2.16), as well as for temporary laptop connections using an RS-485 to RS232 converter (Figure 2.17). The RS-485 output may also be used to install an external communications adapter for connecting a laptop without opening the enclosure.
Section 2 MC-III™ EXP Flow Analyzer Figure 2.
MC-III™ EXP Flow Analyzer Section 3 Section 3—Configuration and Operation via Keypad Calibration of the MC-III™ EXP is a simple matter of entering necessary parameters into the instrument. The process for calibrating the MC-III EXP depends on how the instrument will be used. The keypad can be used to calibrate the MC-III EXP for liquid or gas measurement using preprogrammed units, or for liquid measurement using a calculated divisor.
Section 3 MC-III™ EXP Flow Analyzer Entering a Calibration Factor When the volume is to be expressed in barrels (BBL), gallons (GAL), liters (LIT), cubic meters (M3), or cubic feet (CF), and the flow rate is to be expressed in barrels, gallons, liters, cubic meters or cubic feet per day, per hour, per minute, or per second, the MC-III EXP calculates the divisor automatically; only the turbine meter calibration factor is required.
MC-III™ EXP Flow Analyzer Section 3 Entering a Calculated Divisor When registering the volume in units other than cubic meters, cubic feet, barrels, gallons, or liters, a calculated divisor must be entered in the K-Factor menu instead of the turbine meter calibration factor. Important: When a calculated divisor is used, the units for both the volume display and the volume portion of the flow rate display should be set to USER (no units visible on the display).
Section 3 MC-III™ EXP Flow Analyzer Setting Input Type and Sensitivity The flowmeter signal can be obtained from a magnetic pickup or a pre-amplifier device. The input sensitivity of the MC-III EXP is measured in millivolts (mV) peak-to-peak. This is the threshold value at which the circuitry responds to a signal. If the input signal is less than this value, the MC-III EXP will not count the electrical pulses as a valid turbine meter signal.
MC-III™ EXP Flow Analyzer Section 3 Configuring the Total Display The Total display can be configured for measuring volume in any of five preprogrammed units, any preprogrammed unit times 1,000, or a user-defined unit. Users can specify a decimal point position ranging from 0.1 to 0.0001 of a unit. The device will display volumes up to 10,000,000, however, a maximum of eight digits (including decimals) are visible at a time.
Section 3 MC-III™ EXP Flow Analyzer Configuring the Rate Display The Rate display comprises two parts: a volume unit and a time-base unit. The volume portion of the Rate display can be configured in one of five preprogrammed engineering units or in a user-defined unit (for use with a calculated divisor). To display the volume portion in multiples of 1,000 units, continue scrolling through the volume unit options until the ×1000 entry is displayed, along with the appropriate unit of measure.
MC-III™ EXP Flow Analyzer Section 3 Configuring the 4-20 mA Rate Output Caution: Before performing any 4-20 mA configuration, ensure that all peripheral equipment connected to the 4-20 mA current loop is either disconnected or disabled. Configuring and testing the 4-20 mA output feature on the MC-III EXP with the peripheral equipment in operation may cause false alarms or erroneous operation of the peripheral device or associated equipment.
Section 3 MC-III™ EXP Flow Analyzer To Configure the 4-20 mA Output: Enter the Output menu. Press OUTPUT MENU. Enable or disable the 4-20 mA output. Press UP ARROW to toggle output to “on” or “off”. Press ENTER. If the 4-20 mA output is enabled, the LCD will display the “Low” flow rate and the decimal point in the numeric display will begin blinking. Enter the decimal point position for the “Low” flow rate. The words “4-20 mA LOW” should appear at the bottom of the LCD.
MC-III™ EXP Flow Analyzer Section 3 Configuring the Pulse Output The pulse output feature of the MC-III EXP is typically disabled to reduce current consumption. When the pulse output is not needed, Cameron recommends that this feature be disabled. If the pulse output feature is required, the user will be prompted to enter a pulse output scale factor, which is the volume increment that will cause a pulse output to occur.
Section 3 MC-III™ EXP Flow Analyzer Entering the Slave Address The slave address is a setting used in Modbus® communications. It is a number that ranges from 1 to 65535, excluding 252 to 255 and 64764. If the Modbus® request message contains the matching address, the device will respond to the request. In network arrangements, the device must have a unique slave address. For more information about Modbus® communications, refer to the protocol manual section.
MC-III™ EXP Flow Analyzer Section 4 Section 4—Configuration and Operation via Software The MC-III™ interface software provides easy access to all configuration parameters and is the quickest way to configure the device. While basic parameters can be configured with the keypad (see Section 3), the interface software is the only means of accessing every configurable parameter.
Section 4 MC-III™ EXP Flow Analyzer Connecting the MC-III to a Computer Before attempting to run the interface software, verify that the Scanner is connected to a computer with an RS-485 to RS-232 converter or an RS-485 to USB converter. • See Figure 2.17, page 33, for converter wiring instructions. • See Explosion-Proof Communications Adapter, page A-3, for instructions on installing and wiring an RS485 communications adapter.

Figure 4.17—System Setup screen Time/Date Synchronization The MC-III EXP includes a real-time clock for timekeeping and log time stamps.
MC-III™ EXP Flow Analyzer Section 4 Security Setup Setting a keypad security code will prevent unauthorized personnel from altering calibration data or resetting totals, and the security function is recommended to preserve data integrity of the system. The MC-III EXP’s keypad security feature is disabled at the factory. To enable the security protection, check the “Keypad Lock” checkbox on the System Setup screen, and enter a four-digit lock code in the field below the checkbox. (Do not use “0000.
Section 4 MC-III™ EXP Flow Analyzer To change the slave address, select a number using the “plus” and “minus” buttons on the screen, or using the page-up and page-down keys on your computer keyboard. If Modbus® communication is not used, leave the slave address at the factory setting (1). Baud Rate The baud rate is the number of bits per second that are on the serial port. Baud rates supported by the MC-III EXP range from 300 to 115.2K.
MC-III™ EXP Flow Analyzer Section 4 Bus Delay Bus delay is the amount of time (in milliseconds) that passes before the MC-III EXP attempts to take control of the RS-485 bus and transmit a message back to the requesting device. The MC-III EXP responds very quickly to incoming Modbus® requests—in some cases, too quickly. A configurable delay allows the user to control this response time.
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. Figure 4.
MC-III™ EXP Flow Analyzer Section 4 Rate Display The Rate display comprises two parts: a volume unit and a time-base unit. The volume portion of the Rate display can be configured in one of five preprogrammed engineering units or in a user-defined unit (for use with a calculated divisor). To display the volume portion in multiples of 1,000 units, check the “Multiplier” checkbox.
Section 4 MC-III™ EXP Flow Analyzer K-Factor Entry The K-Factor Entry screen (Figure 4.23) allows users to calibrate the MC-III EXP using a single calibration factor from a turbine flowmeter or multipoint linearization. Users can also configure the MC-III EXP to compensate for the effect of pressure, temperature, and compressibility on gas volume measurements. Figure 4.23—K-Factor Entry screen K-Factor Units K-Factor entry consists of selecting the K-Factor unit and type (linear or multipoint).
MC-III™ EXP Flow Analyzer Section 4 For multipoint calibration, the user selects the Multipoint checkbox, and then enters the number of calibration points he desires using the “plus” and “minus” buttons on the screen or the page-up and page-down keys on a computer keyboard. Up to 12 calibration points may be entered. Frequency and factor data-entry fields are automatically activated for the number of calibration points selected. The user can then enter the appropriate data for each point.
Section 4 MC-III™ EXP Flow Analyzer Gas Volume Correction (Supercompressibility Calculation) Gas turbine meters are calibrated in actual cubic feet (ACF), and measure gas in actual cubic feet. In some applications, a user may benefit from referencing gas measurements back to standard conditions by measuring in terms of standard cubic feet (SCF). The MC-III EXP makes this process quick and easy, by using fixed average values for the flowing gas temperature and flowing gas pressure.
MC-III™ EXP Flow Analyzer Section 4 6. Enter a known compressibility factor, or press “Calculate compressibility from gas comp.” to view a selection of gas compositions (Figure 4.27). • • To automatically calculate the compressibility factor, enter the gas composition and click on “Calculate.” The software will calculate flowing gas compressibility in accordance with the AGA-8 detail method. The K-Factor Entry screen will reappear, and the calculated super-compressibility factor will be displayed.
Section 4 MC-III™ EXP Flow Analyzer 4-20 mA Output Caution: Before performing any 4-20 mA calibration, ensure that all peripheral equipment connected to the 4-20 mA current loop is either disconnected or disabled. Calibrating and testing the 4-20 mA output feature on the MC-III EXP with the peripheral equipment in operation may cause false alarms or erroneous operation of the peripheral device or associated equipment.
