  • Page 2 Mounting Your MC-III MC-III EXP 1. Position the MC-III EXP above the flowmeter pickup adapter. 2. Plug the connector of the MC-III EXP cable into the magnetic pickup and hand-tighten the knurled nut on the connector. 3. Mount the MC-III EXP on the flowmeter pickup adapter with the display facing the desired direction, and tighten all sections of the pipe union. Before mounting an ATEX-approved device, see “MC-III EXP (ATEX)” below. Pipe plugs Caution: Do not use Teflon tape on threads of the union, adapter, or pipe plugs. MC-III EXP (ATEX) ATEX-approved MC-III EXPs are fitted with a standoff tube adapter when pur- Explosion-proof enclosure chased with an ATEX-approved Barton 7000 Series or NuFlo turbine meter.
  • Page 3 MC-III WP 1. Position the MC-III WP above the flowmeter. 2. Plug the MC-III WP cable connector into the magnetic pickup and hand- tighten the knurled nut on the connector. 3. Screw the MC-III WP mount onto the flowmeter threads surrounding the magnetic pickup. 4. With the display facing the desired direction, tighten the two screws on either side of the mount to prevent horizontal shifting. 5. With the display oriented vertically in the desired direction, tighten the two hex- head bolts on either side of the top section of the mount to prevent vertical shifting.
  • Page 4 Wiring Your MC-III CAUTION—All field wiring must conform to the National Electrical Code, NFPA 70, Article 501-4(b) for installations within the United States or the Canadian Electric Code for installations within Canada. Local wiring ordinances may also apply. All field wiring must have a wire range of 22 to 14 AWG and terminal block screws must be tightened to a minimum torque of 5 to 7 in-lb to secure the wiring within the ter- minal block.

If an external power supply is to be used (the battery will provide backup power), wire the power supply to terminal block TB3. For MC-III WP Div. 2 installations, connect a protective overcurrent device rated at 0.5A maximum (circuit breaker or fuse) to the positive supply line of the DC power supply in the safe area. A disconnect switch for the power supply must also be installed in the safe area. A Zener diode (Part No. 1.5KE33CA) must be installed for CE approval.

The maximum current rating of the pulse output circuit is 60 mA at 50 VDC. A Zener diode (Part No. 1.5KE56CA) must be installed for CE approval. EXT POWER Resistor may be included in pulse readout device. Size the resistor to limit the current A&S to 60 mA. Leave this POWER SUPPLY end of shield 5 to 50 VDC disconnected.
  • Page 7 6. If a flowmeter frequency output is to be used to provide flow rate and/ or total information to peripheral equipment, wire the power supply and the frequency readout device to terminal block TB3. The readout device must operate with 50 mA or less. Leave this POWER SUPPLY TB3 MARKINGS: end of shield 5 to 30 VDC GND = SIGNAL GROUND disconnected.

  • Page 8 Configuring with the Keypad Most routine functions can be configured from the six-button keypad. This guide provides instructions for entering a calibration factor, and selecting the units for the total and flow rate displays. For instructions on configuring all other parameters, see the MC-III user manuals.

  • Page 14 Configuring with Software Gas Volume Correction Gas turbine meters measure gas in actual cubic feet (ACF). To measure gas in terms of standard cubic feet (SCF), flowing gas pressures and temperatures must be referenced back to standard conditions, based on fixed (average) parameters. These parameters are accessible only through MC-III interface software. To configure the instrument to measure gas flow in standard cubic feet, perform the following steps: 1. Select Go to MC-III Main from the Device Autorun Options screen. 2. Click the K-Factor Entry icon in the scroll bar at left. 3. In the Gas Volume Correction section of the K-Factor Entry screen, check the Enable volume correction checkbox (see screen on page 15). The STANDARD annunciator will appear on the LCD. 4. Adjust atmospheric pressure, if desired. 5. Enter the base pressure and unit and the base temperature and unit. 6. Enter the working pressure, working temperature, and corresponding units.

  • Page 15: Multipoint Linearization

    Multipoint Linearization The MC-III can be calibrated with up to 12 calibration points using MC-III interface software. (Only single-point calibration is supported through the Configuration Wizard.) To configure the instrument with these parameters, perform the following steps: 1. Select Go to MC-III Main from the Device Autorun Options screen. 2. Click the K-Factor Entry icon in the scroll bar at left (see screen on page 14). 3. Select the factor units. 4. Select the multipoint checkbox. 5. Enter the number of calibration points desired using the “plus” and “minus” buttons (up to 12 points maximum). 6.
