1.3 API2540 Liquid Volume Correction User Program Overview

The Liquid Correction Program is designed for the ROC300-series units equipped with FlashPACs and the FloBoss 407. The Liquid Correction Program corrects the measured flow of crude oils, oil generalized products, LPG, and water by converting values to standard temperature and pressure levels. The Liquid Correction Program monitors the current flow rate, temperature, and pressure, and to calculate a corrected flow value for standard conditions based upon density value, sediment, and water percent value, vapor pressure, and the meter slippage factor.

1-1

Rev 05/04

Rev 05/03

API2540 Liquid Volume Correction User Program

The Liquid Correction Program accumulates the volume of the flowing fluid and can be configured to perform calculations for up to three different flows in the ROC306 and ROC312, five flows in the

ROC364, or four flows in the FloBoss 407.

The Liquid Correction Program tracks two accumulated volumes for each flow. One accumulation is the volume since contract hour or last manual reset and the second accumulation is a running total that rolls over at 9,999,999. At contract hour or manual reset, flow and minutes today are transferred to flow and minutes yesterday.

The Liquid Correction Program supports the following liquids:

♦

Crude oil.

Generalized oil products (jet fuel, diesel, oil, and gasoline).

LPG (Liquefied Petroleum Gas).

Water.

The Liquid Correction Program supports the following standards:

♦ API2540 Tables 5A, 5B, 6A, 6B, 34, 53, 53A, 53B, 54, API21, API5, AGA3/1992 and was developed according to API/ANSI/AGA standards. Refer to Appendix A for a list of all applicable standards.

The Liquid Correction Program supports the following types of inputs:

♦

Pulse (mass or volume).

Analog Flow (mass or volume).

Analog Differential Pressure (DP).

Density.

Vapor Pressure.

Water and Sediments.

An uncorrected flow can be determined by one of the following inputs:

♦

Pulse Input (such as from a turbine).

Analog Input (such as from a Vortex or MicroMotion).

Differential Orifice Metering (flange taps only).

The Liquid Correction Program application domain is limited, by API standards, to correcting the flow of densities, pressures, and temperatures within a custody transfer degree of accuracy. The domain borders vary according to the product class and parameter values. The calculation automatically adjusts the Liquid Type between LPG and Crude Oil if the input density fluxuates

Whenever a domain violation occurs, an error message displays and stored in the Event Log, with the

ERR tag, the Domain Limit as “old value”, and the Current Value of the parameter. When the violation clears, “No Error” displays and a clear event is logged with the CLR tag. A real-time stamp is appended to each event. In error mode, calculations use the closest domain formulas.

Rev 05/03 1-2

API2540 Liquid Volume Correction User Program

NOTE: Further interpretation of the volumes calculated and accumulated during domain violation periods is the user’s sole responsibility.

Because domain limits for flowing pressure corrections and flowing temperature corrections overlap, the Liquid Correction Program assumes temperature-driven domain below 500 kPa (75 PSIA) and pressure-driven domain above 500 kPa. The associated error is less than 50 PPM.

Inputs

Select API2540 > API 2540 Setup and click Inputs to define the Meter Input, Temperature Input, Static

Prs. Input, Vapor Prs. Input, Density Input, and Sediment & Water inputs.

Figure 3-5. Inputs

Meter Input – Source of the uncorrected 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 (m

or kg for metric and bbl or lbm for US). If 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, m

, lbm or bbl per day).

When using an Analog Input, such as from a Vortex transmitter, the rate must be m

/hour or kg/hour in metric, and bbl/hour or lbm/h in US units.

When using a differential Analog Input for orifice metering, the scaling must be kPa in Metric and in. H

O 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 Prs. Input – Location where pressure of the fluid is originated. The pressure is assumed to be 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.

3-6 Rev 05/03

API2540 Liquid Volume Correction User Program

Density Input – Location where the density of the fluid is originated.

There are two typical practical applications:

This parameter is manually (Undefined) entered, to a value certified by a laboratory. The

Value is assumed to be at base temperature and pressure, except API rounding. No corrections are made on this Value.

A flow density meter can be assigned to the “Filter” EU value of an Analog Input. The current Value of the floating-point parameter is assumed at flow conditions, so temperature and pressure corrections are applied. Softpoint and FST registers are also accepted. The value transferred or set displays as the (Density) Value in kg / m

or Deg API.

Sediment & Water Input – Analog Input weight percentage, such as from a BS&W device, Softpoint,

FST Register, or manual (Undefined) entry. Valid Domain 0-100.

3.1.5

Slippage Factors

Select API2540 > API 2540 Setup and click Slippage Factors to “fine tune” each individual meter, based on proven calibration data described in API Manual of Petroleum Standards, Chapter 12. This screen is only accessible for Pulse or Analog Meter Types.

Figure 3-6. Meter Slippage Factors

Up to five different Meter Slippage Factors may be entered for various flow rates.

If the first flow rate is set to 0.0, the rest of the table is ignored and a Meter Slippage Factor of

1.0 is used.

If only one flow rate / meter factor pair is entered, the program uses that Meter Slippage Factor for all flow rates. Enter a unique Meter Slippage Factor.

If more than one flow rate / meter factor pair is entered, the program uses linear interpolation to arrive at the Meter Slippage Factor for the current raw flow rate. Each meter flow rate entered must be higher than the previous flow rate entered, such as:

Meter Value 1 < Meter Value 2 < Meter Value 3, and so forth.

If an error occurs due to improper configuration, such as negative numbers, the program sets the Meter Slippage Factor to 1.0.

Meter Value 1 – First flow rate for 1 st

Meter Slippage Factor. Typically 20% of maximum flow.

Factor 1 – Meter Slippage Factor for 1 st

flow rate.

Rev 05/03 3-7

Meter Value 2 – Second flow rate for 2 nd

Meter Slippage Factor. Typically 40% of maximum flow.

Factor 2 – Meter Slippage Factor for 2 nd

flow rate.

Meter Value 3 – Third flow rate for 3 rd

Meter Slippage Factor. Typically 60% of maximum flow.

Factor 3 – Meter Slippage Factor for 3 rd

flow rate.

Meter Value 4 – Fourth flow rate for 4 th

Meter Slippage Factor. Typically 80% of maximum flow.

Factor 4 – Meter Slippage Factor for 4 th

flow rate.

Meter Value 5 – Fifth flow rate for 5 th

Meter Slippage Factor. Typically 100% of maximum flow.

Factor 5 – Meter Slippage Factor for 5 th

Calculated Factor – Displays the actual calculated meter factor to be used in calculations. The value is transferred to the API Calculations (Figure 3-2) as Meter Slippage Factor.

Select API2540 > Data Transfer to configure eight individual register data transfers. The values defined in Source definition data 1 to 8 are transferred into target Destination data 1 to 8. The actual value for each field displays in the corresponding Value field. Only floating-point values can be transferred, even though other data options are selectable.

The Register Transfer screen is set to run by setting the Scan Period to a value greater than zero. The actual Scan Time is typically 2 seconds.
