Geometry Error

During calibration and commissioning of an 8", 0.4 beta Venturi meter Prognosis detected a geometry entry error. It was subsequently confirmed that there was an erroneous throat diameter in use. The resulting flow prediction bias would have been 1.6%.

However, as Prognosis highlighted the issue before the meter entered service, the issue was corrected, and a mismeasurement was avoided.

With a typical meter throughput of 800,000Sm3 per day, the cost* of an error of this magnitude would be:

after 1 day $ 3661.40
after 30 days $ 109848.53
after 1 year $ 1336743.20

based on gas price of $ 0.29/Sm3.
