Corrector Meter

Volumetric calculation

Defines how the volume will be calculated. There are two options available for selection:

• API Liquid

• AGA-7 1996

• API 14.4

Pulse Count Calculation

Policy

There are three options available for selection:

• Calculate Pulse Count from Uncorrected Volume

• Calculate Uncorrected Volume from Pulse Count

• None

  Note: For more information, refer to the section Pulse Count Calculation Policy.

Frequency low flow cut off

Enter the frequency value below which volume correction calculations are invalid. The frequency value is pulse count / flow time in seconds.

K factor

Enter the number of pulses per unit volume.

Meter factor

Enter the meter factor. This allows you to correct for the difference between the manufacturers' defined pulse rate, and the values that the meter is recording.

Corrector Type Code

Enter the code associated with your corrector type.

Electronic Corrector Number

Enter the number associated with the type of electronic corrector that you have.

Delivery Pressure

Enter the delivery pressure. The value that can be entered in this field must adhere to the following specifications:

• Minimum Value: 0 PSI

• Maximum Value: 100,000 PSI

Temperature Compensation

Check Temperature Compensation to compensate for temperature.

Drive Rate

Enter the drive rate from one of the following selections:

• 5 - Drive rate 5

• 10 - Drive rate 10

• 100 - Drive rate 100

• 1000 - Drive rate 10,000

Install Date

Enter the date on which the corrector meter was installed.

Corrector Battery

Battery Type

Enter the battery type information.

Install Date

Enter the date on which the battery was installed.

Corrector EFM

Averaging error method

Defines the method of correcting for Historical averaging error. There are two options available for selection:

• Volume Ratio

• None

Calculate Volume Ratio

Calculate an observed volume obtained from dividing the Remote Terminal Unit (RTU) volume by the host-calculated volume.

Enable Automatic GQ

Download

Enables the automatic download of the connected zone gas analysis when the defined deadbands have been exceeded.

CM EFM Volume Ratio

Check

Enable

Select the checkbox to enable the CM Electronic Flow Measurement (EFM) volume ratio check.

High threshold

Enter a value to define the high threshold of the CM EFM volume ratio check.

Low threshold

Enter a value to define the low threshold of the CM EFM volume ratio check.

Auto replace (outside threshold)

Select the checkbox to to indicate that the reading should be replaced when the RTU volume is outside the threshold.

Auto replace (when Vref = 0)

Select the checkbox to indicate that the reading should be replaced when the RTU volume is equal to 0. The reading should be replaced with a calculated volume.

Auto replace (when Vcalc = 0)

Select the checkbox to indicate that the reading should be replaced when the host volume is equal to 0. The reading should be replaced with the RTU volume.

Severity

Defines the severity to be associated with the rate of change check. There are two options available for selection:

• Invalid. The record will be marked as invalid if the check fails.

• Flagged. The record will be marked as flagged if the check fails.

CM Uncorr. Volume Reas

Chk

Enable

Select the checkbox to enable the uncorrected volume reasonability check.

High threshold

Enter a value to define the high threshold of the uncorrected volume reasonability check.

Low threshold

Enter a value to define the low threshold of the uncorrected volume reasonability check.

Severity

Enter a value to define the severity to be associated with the uncorrected volume reasonability check for corrector meters.

CM Uncorr. Volume ROC Chk.

Enable

Select the checkbox to enable the uncorrected volume rate of change check for corrector meters.

Tolerance (%)

The rate of change (ROC) percentage that the system is equipped to tolerate before the check triggers an error situation.

Severity

Defines the severity to be associated with the uncorrected volume rate of change check.

Missing Parameter Check

(corrector)

Enable

Select the checkbox to enable the Missing Parameter Check.

Pressure

Select how you would like the program to respond in the event of a missing parameter for pressure. There are two options available for selection:

• Partial Data. If pressure is missing, estimate pressure and recalculate volume and energy.

• No Data. If pressure is missing, treat entire record as suspect and estimate.

Temperature

Select how you would like the program to respond in the event of a missing parameter for temperature. There are two options available for selection:

• Partial Data. If temperature is missing, estimate temperature and recalculate volume and energy.

• No Data. If temperature is missing, treat entire record as suspect and estimate.

Flow Time

Select how you would like the program to respond in the event of a missing parameter for flow time. There are two options available for selection:

• Partial Data. If flow time is missing, estimate flow time and recalculate volume and energy.

• No Data. If flow time is missing, treat entire record as suspect and estimate.

Pulse Count

Select how you would like the program to respond in the event of a missing parameter for pulse count. There are two options available for selection:

• Partial Data. If pulse count is missing, estimate pulse count and recalculate volume and energy.

• No Data. If pulse count is missing, treat entire record as suspect and estimate.

Mass

Select how you would like the program to respond in the event of a missing parameter for mass. There are two options available for selection:

• Partial Data. If mass is missing, estimate mass and calculate volume and energy.

• No Data. If mass is missing, treat entire record as suspect and estimate.
