This is a specialize service to evaluate the performance of the metering systems, in complying with the requirements as
laid down in the American Petroleum Institute (API)
Measurement Standards. The major components of a
Technical Audit are;
1.An evaluation of the condition and design of each metering
system with regards to Electronic Condition as per API
Standard.
2. Verification of throughout, calculations for Gross Measured
Volume Standard Volume Validation of any other Computer
Constants and or functions.
3. Calibration checks on Temperature and Pressure
Instrumentation.
4.Check on-line sample analysis Procedures and function
test autosampler.
5. Establishing flow curves for meters over the flow range for
linearity and repeatability.
6.Verification of Proving calculation and examination of
current prover loop calibration Certificate, checking current
base volume is in use and correct defect switch pair is
selected. Examination of internal condition of Prover.
7. Prove that all critical valves in system are bubble tight when
closed under normal operating condition; function check
associated leak detector system.
Calibration of instrumentation can also be conducted in the
course of the exercise to reduce errors and improve overall
measurement uncertainty.
