PROVER
10
Used switches
Sequence of switches used or the average of all detectors
Switches volume
Prover base volume at switch point
K-factor calculation
Method of K-factor calculation selectable
Confidence
User confidence level of calculation implemented
Required runs
Least amount of run required for a sucessful prove
Pulse interpolation
Method for pulse interpolation – non or double chronometry
Minimum pulses
Minimum allowable pulses for a prove, default 10,000
Max KF deviation
Maximum deviation limit for new K-factor compare to previous
value
Max MF deviation
Maximum deviation limit for new MF compare to previous value
Please note that some parameters will not be needed, depending on previous choices.
The K-factor calculation method can be selected from
• Traditional repeatability
• Statistical repeatability
• Uncertainty calculations.
Provers are normally set to traditional repeatability. Uncertainty can also be selected but this
requires a high repeatability and more runs than traditional repeatability.
Pipe correction
This section is for liquid provers only,
Here the user must enter the corrections for the liquid prover stream for CTSp (prover expan-
sion due to temperature) and CPSp (prover metal expansion due to pressure)
