  • Page 29: Remote Reset Input

    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).

  • Page 30: Pulse Output

    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).

  • Page 31: Analog (4-20 Ma) Rate Output

    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 two- conductor 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.

  • Page 32: Flowmeter Frequency Output

    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).

  • Page 38: Entering A Calculated Divisor

    Section 3 MC-III™ EXP Flow Analyzer 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).

  • Page 39: Setting Input Type And Sensitivity

    MC-III™ EXP Flow Analyzer Section 3 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.

  • Page 40: Configuring The Total Display

    Section 3 MC-III™ EXP Flow Analyzer 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.

  • Page 41: Configuring The Rate Display

    MC-III™ EXP Flow Analyzer Section 3 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).
