Meter Input — Source of the uncomcted measured flow. Typically, this links to a Pulse Input engineering units Value, or the Analog Input Filter engineering unit value. Softpoint parameters. FST Registers. or manual (Undefined) mode are also accepted. The value transferred or set displays as the (Meter) Value field.
When using a Pulse Input. this is typically configured as “rate.” but the user program calculates pulse values starting from the Accumulated Pulses (Accum’d Pulses) in the Pulse Input (m3 or kg for metric and hhl or Ibm for US). It’ the Meter Type is configured as Pulse Input, and the actual value is manual (Undefined), or from a different register in the ROC (such as a Softpoint), the user program interprets the number as a daily rate (kg. m3. Ibm or bbl per day).
When using an Analog Input, such as from a Vortex transmitter, the rate must be m’fhour or kg/hour in metric, and bbl/hour or Ibm/h in US units.
When using a differential Analog Input tbr orifice metering, the scaling must be kPa in Metric and in. H20 in US units.
Temperature Input — Location where the process temperature of the fluid is originated. Typically. this floating-point parameter is assigned to the “Filter” engineering units (EU) value of an Analog Input. Softpoint parameters. FST registers, or manual (Undefined) mode are also accepted. The value transferred or set displays as the (Temperature) Value in Deg C or Deg F.
Static Pt-s. Input — Location where pressure of the fluid is originated. The pressure is assumed to he consistent with the Vapor Pressure. Typically. this floating-point parameter is assigned to the “Filter” EU value of an Analog Input or MVS. Softpoint parameters. FST registers, or manual (Undefined) mode are also valid. The value transferred or set displays as the (Pressure) Value in kPa or PSI.
Vapor Prs. Input — Location where the vapor pressure of the fluid is originated. The vapor pressure is assumed to be absolute pressure and consistent with the Process Pressure (see above). Typically. this floating-point parameter is assigned to the “Filter” EU value of an Analog Input, Softpoint. FST Register. or manual (Undefined) mode. The value transferred or set displays as the Value in kPa or PSI.
