Meter General

Metering Method

Defines the meter type.

Choices are the following:

• Orifice Meter — A meter measuring flow by orifice technology.

• Pulse Meter — A meter measuring flow by pulse counting technology.

• Coriolis Meter — A metering device that measures mass flow rate by measuring tube displacement resulting from Coriolis effect.

• Manual Meter — A manual meter is used to collect information when there is no telemetry. It typically consists volume and energy information. But if it is associated with a Gas Quality record, the energy can be calculated from the Volume. Volume can be calculated from the mass for manual meters with a Data Source of Manual Meter.

• Balance Calculated — When a station volume is calculated from several meter runs, the result can be stored as meter data instead of a station volume record. This allows for the system to apply the full inventory of meter validation operations.

• Line Pack — A meter measuring volume between two points.

• Corrector Meter — A volume correction measurement device.

Accumulator Meter

Select the checkbox if your metering device is of the accumulator-type. For more information, refer to If your metering device gathers accumulator data.

Accumulator Rollover

Enter the maximum value that the accumulator goes up to before it resets. For more information about how Measurement accounts for the rollover, refer to Account for an accumulator's rollover. The rollover value entered here is assumed to be in the units of the value being calculated.

Field device local timezone

The time zone in which the field device collecting the metering data is located.

Field device contract hour

The contract hour of the field device. The Field Device Contract Hour can be used to timestamp the daily aggregated rows with the contract hour and time zone used by the field device.

If CD_FIELD_DEVICE_AGGREGATES is set to Y in the configDesc table, the contract hour and time zone will be supplied by the field.

Official Contract Hour

The Official Contract Hour can be used to timestamp the daily aggregated rows with the contract hour used by the system's time zone, as opposed to using the contract hour and time zone supplied by the field.

The system's time zone is set in the configDesc table, in CD_CONTRACT_TIMEZONE_CODE.

If the customer wishes to use the Official Contract Hour according to the system time (using the time zone entered in CD_CONTRACT_TIMEZONE_CODE), as opposed to the information supplied by the field, they need to set CD_FIELD_DEVICE_AGGREGATES to N in the configDesc table.

Alternate Contract Hour

This allows the customer to supply an Alternate Contract Hour.

Note: The Alternate Contract Hour is not used for any data processing. It is purely informational.

Supercompressibility calculation

Select your supercompressibility calculation method from the dropdown list:

• NX-19 GCN

• NX-19 Complete

• AGA-8 1992 Detail

• AGA-8 1992 Gross 1

• AGA-8 1992 Gross 2

• AGA-8 2017 Detail

• AGA-8 2017 Gross 0

• AGA-8 2017 Gross 1

• AGA-8 2017 Gross 2

• AGA-8 2017 Gross 3

• AGA-8 2017 GERG

  Notes: For the purposes of the Supercompressibility calculation, AGA-8 2017 Detail and AGA-8 2017 Gross 1 and 2 are the same as their AGA-8 1992 counterparts.

  The AGA-8 2017 supercompressibility options cannot be used in conjunction with host-calculated meters or gas qualities (GQ) at this time. This functionality is expected in a future release.

Telemetry calculation policy

• Recalculate Volume And Energy

• Recalculate Energy

• None

• Recalculate Volume, Energy, and Dewpoint

• Recalculate Energy and Dewpoint

• Recalculate Dewpoint

Static pressure setting

Defines whether the pressure values received are absolute or gauge.

Config calculation policy

Defines the recalculation policy for volume, energy and volume ratio with respect to configuration changes. The choices are as follows:

Calculate — Calculate volume/energy or volume ratio on a config change.

None — Do not calculate volume/ energy or volume ratio on a config change.

Enable flow editor calculations

Determines whether energy and/or volume calculations are performed when you edit temperature or pressure in the Meter Data Editor window.

Enable flow editor dewpoint calc

Determines whether hydrocarbon dewpoint calculations are performed when volume recalculation is performed in the Meter Data Editor window.

Calibration

AVEVA Measurement Advisor will test for variances in volume and energy percentages and determine if corrections are needed.

Percent Energy Threshold

AVEVA Measurement Advisor calculates the difference between the corrected energy and the current energy. If the difference is greater than the threshold, then corrections will be required. You can enter values either as a percentage or as an absolute value.

Percent Volume Threshold

AVEVA Measurement Advisor calculates the difference between the corrected volume and the current volume. If the difference is greater than the threshold, then corrections will be required. You can enter values either as a percentage or as an absolute value.

Absolute Energy

Threshold

AVEVA Measurement Advisor calculates the difference between the corrected energy and the current energy. If the difference is greater than the threshold, then corrections will be required. You can enter values either as a percentage or as an absolute value.

Absolute Volume

Threshold

AVEVA Measurement Advisor calculates the difference between the corrected volume and the current volume. If the difference is greater than the threshold, then corrections will be required. You can enter values either as a percentage or as an absolute value.
