Calculation
Ctsp
The Ctsp is calculated by:
| Where | ||
|---|---|---|
| αc | = | Cubic temperature coefficient |
| αl | = | Linear temperature coefficient |
| Tp | = | Prover temperature |
| Trf | = | Prover reference temperature |
Cpsp
The Cpsp is calculated by:
| Where | ||
|---|---|---|
| λ | = | Pressure coefficient |
| Pp | = | Prover pressure |
| Prf | = | Prover reference pressure |
K-factor
The K-factor is calculated by:
| Where | ||
|---|---|---|
| Kf0 | = | Uncorrected K-factor |
| Ctlm | = | Correction for temperature of the liquid at the meter |
| Cplm | = | Correction for pressure of the liquid at the meter |
| Ctlp | = | Correction for temperature of the liquid at the prover |
| Cplp | = | Correction for pressure of the liquid at the prover |
| Ctsp | = | Correction for temperature on steel of the prover |
| Cpsp | = | Correction for pressure on steel of the prover |
| IntF | = | Interpolation factor |
Meter Factor
The meter factor is calculated by:
| Where | ||
|---|---|---|
| Kb | = | Base K-factor |
| Kf | = | K-factor |
Corrected volume
The corrected prover volume is calculated by:
| Where | ||
|---|---|---|
| Vb | = | Base prover volume |
Required pulses
The number of required pulses is calculated by:
| Where | ||
|---|---|---|
| nm | = | Number of pulses |
