    In most cases, all of these variables are pre-configured HART Comm. 1, 3 at the factory. Configuration may be required if your Model 8800C is not configured or if the configuration variables need revision. Tag is the quickest way to identify and distinguish between flowmeters.

  • Page 54: Pv Units

    After changing flow units, be sure to send data to the transmitter so that the associated variables (4–20 mA points, etc.) will be recalculated by the microprocessor. The Model 8800C recalculates all variables that depend on units. You may then change any of the remaining parameters.
  • Page 55 SCFH NCMM NCMH NCMD The model 8800C allows you to measure Standard or Normal Flow Units. Configure the software in one of two ways: 1. Enter Density Ratio to convert from actual flow rate to standard flow rate. 2. Enter the process and base conditions. (The Model 8800C electronics will then calculate the density ratio for you).

  • Page 63 Operation D/A Trim (Digital-to-Analog Trim) HART Comm. 1, 4, 3, 1, 4 Digital-to-Analog Trim enables you to check and trim the analog output in a single function. If the analog output is trimmed, it will be scaled proportionally through the range of the output. To trim the digital-to-analog output, initiate the D/A Trim function and connect an ammeter to the loop to measure the actual analog output of the meter.
  • Page 64 HART Comm. 1, 4, 3, 2, 1 The Model 8800C comes with an optional pulse output option (P). This enables the flowmeter to output the pulse rate to an external control system, totalizer, or other device. If the flowmeter was ordered with the pulse mode option, it may be configured for either pulse scaling (based on rate or unit) or shedding frequency output.

Example: The pulse output will maintain a 50 percent duty cycle for all frequencies 50% Duty Cycle NOTE The scaled pulse output is designed to operate between 0 and 10,000 Hz. The electronics will not accept a conversion factor that would result in a pulse frequency outside that range.

The four user-alterable parameters associated with the digital signal processing on the Model 8800C include low-pass filter corner frequency, low-flow cutoff, trigger level, and damping. These four signal conditioning functions are configured at the factory for optimum filtering over the range of flow for a given line size and service type (liquid or gas).
  • Page 69 Operation Sig/Tr (Signal/Trigger Level Ratio) HART Comm. 1, 4, 4, 1, 3 The Signal to Trigger Level Ratio is a variable that indicates the flow signal strength to trigger level ratio. This ratio indicates if there is enough flow signal strength for the meter to work properly. For accurate flow measurement, the ratio should be greater than 4:1.
