Options

Spool Correction Factor

• User entered

Select this option to enter a single multiplier for the correction factor – if no correction is made set this value to 1

• Calculated

Select this option to calculate the correction factors using the manufacturers equations

Calibration Correction

• None

Select this option if you do not wish to correct the flow rate for the calibration curve

• Before Spool Correction

Select this option if you wish to correct the flow rate based on the calibration data before applying the correction for spool temperature and pressure

• After Spool Correction

Select this option if you wish to correct the flow rate based on the calibration data after applying the correction for spool temperature and pressure

• Normal volume
• Energy

Enter elapsed time as

• Duration

Select this option to enter the elapsed time as a duration

• Start and end time

Select this option to have the duration calculated from a start and end time

Totals

• Use start and end totals

Calculation

Flow rate

The flow rate is calculated using K176 – Instromet – Ultrasonic Meter Flow Rate.

Totalisation

The total is calculated by combining the flow rate calculation with the totalisation calculation C203.
