Understand the items displayed on the Prover Control window

Prover Name

Name of the prover record.

Base Volume

This is the base volume of the prover in m3. This field holds a floating point number with four decimal places of accuracy.

Prover Status

The name of the status point to hold the status of the prover as indicated by the Programmable Logic Controller (PLC). The status of the prover as indicated by the PLC is either "busy" or "idle".

Prover SW Status

The Prover SW Status is an internal software status that the application maintains. The statuses available are:

• Not In Progress — The application is ready to start a new prove.

• In Progress — The application is performing meter proving.

• Wait Busy — The application is waiting for the PLC to go into a busy state.

• Busy Run — The application is waiting for the PLC status to transition to a Transit or Idle state. If the status changes to Busy, it will move on to the next stage. Otherwise, the status will stay in a state of Busy Run.

• Wait Value — The application interprets the information provided by the analog, rate, and status points and performs temperature, pressure, and density validations in addition to deviation validation, API and Meter Correction Factor (MCF) calculations, and repeatability validation.

Calc Method

The calculation method in use by the prover.

Prover Type

Type of prover in use.

Pipe Thickness

The prover pipe thickness in mm. This field holds a floating point number with one decimal place of accuracy.

Pipe Diameter

The prover pipe diameter in mm.

Seal

If the status point is defined by your Administrator, proving will check for seal failure during the proving sequence. This field will indicate if there are any issues with the seal.

EOR (End of Run)

This field will indicate that the end of run has been achieved.

Meter Name

The name of the meter that is associated with the prover.

K-factor

This is the number of pulses per 0.1 m³ for this meter. This field holds an integer value.

Max Count Deviation

This is the maximum count deviation allowed for this meter. If the difference between the minimum and maximum pulse counts is greater than this value, you cannot accept the Meter Correction Factor (MCF) result.

Current Count Deviation

This field holds the absolute value of the difference between maximum and minimum number of counts for the four runs. If this value is greater than the allowable limit, the application marks the runs in violation by putting a (*) next to the count number for those runs. You cannot accept the MCF if this value is greater than the allowable limit. You must reprove the faulty runs, or complete an autoprove (prove 4 runs) to clear this situation.

Max Repeatability %

This field lists the maximum allowed deviation of prover run counts.

Current Repeatability %

This field lists the current value of the prover as it goes along. A run is marked as bad if the current repeatability % exceeds the maximum repeatability %.

No. Runs to Prove

Number of runs left to prove.

Batch ID

Enter your Batch ID information.

Tender ID

Enter your Tender ID information.

Product

Enter your Product information.

Density

Enter your Density Information.

Abort Prove

For more information, see Abort a Meter Prove run.

Clear Prove

Select Clear Prove to clear the prove information.

Accept

For more information, see Accept a meter factor.

Override Accept

Select Override Accept to override any error messaging and accept the prove. For more information, see Accept a meter factor.

Run Number

Provides the run information for the meter prove.

Temperature (ºC)

Provides the temperature information associated with both the meter and the proving device.

Pressure (PSI)

Provides the pressure information associated with both the meter and proving device.

CTS

Correction factor for Temperature on Steel.

CPS

Correction factor for Pressure on Steel.

CTL

Correction factor for Temperature on Liquid.

CPL

Correction factor for Pressure on Liquid.

Flow Rate (bbls/hr)

Provides the flow rate information.

Density

Provides the density information.

Count

Proves the accumulator information.

Meter Factor

Supplies the Meter Factor that was applied to the run.

Good Run?

Provides an indication of whether the run was successfully executed.

(Small Pvr) Det Temp

The fields in this column list the temperature of the external detector in small volume provers.

Report #

Number of the report with which the meter prove is associated.

Reports Completed

Provides the number of reports that have been completed.

Max Count Deviation Exceeded?

This indicates whether the maximum count deviation has been exceeded. If it has been, the run will be considered bad.

Ambient Temperature (ºC)

The ambient temperature in degrees Celsius. This is supplied by an analog point.

CTS Prover

Correction factor for Temperature on Steel for the prover.

CPS Prover

Correction factor for Pressure on Steel for the prover.

CTL Prover

Correction factor for Temperature on Liquid for the prover.

CPL Prover

Correction factor for Pressure on Liquid for the prover.

CTL Meter

Correction factor for Temperature on Liquid for the Meter.

CPL Meter

Correction factor for Pressure on Liquid for the Meter.

Runs Remaining

How many meter proving runs that have yet to take place.

Batch ID

Enter the batch ID number. For non-batching meters, the Batch ID can consist solely of product or, optionally, can be in the same format as for batching meters (product-xxx).

Product

Product being transported by the meter.

Coef. of Cubical Exp.

The coefficient of cubical expansion (per °F) of the material of which the prover is made.

Area Thermal Coef.

This field lists the area thermal coefficient of expansion for the small volume prover chamber.

Linear Thermal Coef.

This field lists the linear thermal coefficient of expansion of the displacer shaft in small volume provers.

Old Meter Factor

This supplies the old meter factor.

New Meter Factor

This supplies the new meter factor.

Run Number

This field reports the number of the run.

Temperature

In / Out

This field reports the incoming and outgoing temperatures reported by the proving process.

Press

In / Out

This field reports the incoming and outgoing pressures reported by the proving process.

Valid Reading

T / P / D

This field provides information on whether the temperature (T), pressure (P), and density (D) information supplied by the prover is valid.
