Flow Meter Calibration Cost at 86% wet calibration percentage: a worked example

What does the result look like when wet calibration percentage reaches 86%? The full calculation is worked below with real intermediate numbers. Use this when budgeting annual flow meter calibration, comparing in-house cal lab costs vs. third-party service, or justifying investment in a dedicated flow calibration rig.

The inputs for this scenario

  • Flow meters due for calibration: 24 meters (unchanged)
  • Average calibration cost per meter: 450 $ / meter (unchanged)
  • Wet calibration percentage: 86 % (raised for this scenario; the documented default is 75)
  • Fixed calibration rig overhead: 3,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable calibration cost = meters due x cost per meter x (wet cal percentage / 100)) to the inputs above produces each figure below.
  • At this operating point the engine returns 12,788 $ for total flow meter calibration cost, the number this scenario is built around.
  • At this operating point the engine returns 533 $ / piece for average cost per meter calibrated.
  • At this operating point the engine returns 9,288 $ for variable calibration cost.
  • At this operating point the engine returns 3,500 $ for fixed rig overhead.

How this compares with the baseline

  • Against the tool's baseline example, where wet calibration percentage sits at 75% and the headline result is 11,600 $, this scenario comes in 10.24% above the baseline at 12,788 $.
  • A figure at this level is achievable when wet calibration percentage is genuinely sustained, not just peaked for a shift. It assumes one blended cost per meter and a single wet-cal share, so mixed meter sizes, line shutdown costs, and travel are not separated out and should be added if material.

Results at a glance

  • Total flow meter calibration cost: 12,788 $ (headline result)
  • Average cost per meter calibrated: 533 $ / piece
  • Variable calibration cost: 9,288 $
  • Fixed rig overhead: 3,500 $
