Flow Meter Calibration Cost at 54% wet calibration percentage: a worked example

Suppose wet calibration percentage falls to 54%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate total annual calibration cost for your flow meter fleet including per-meter lab fees, technician labor, reference standard maintenance, and fixed calibration rig overhead.

The inputs for this scenario

  • Flow meters due for calibration: 24 meters (held at the documented default)
  • Average calibration cost per meter: 450 $ / meter (held at the documented default)
  • Wet calibration percentage: 54 % (the input this scenario stresses; the baseline uses 75)
  • Fixed calibration rig overhead: 3,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable calibration cost = meters due x cost per meter x (wet cal percentage / 100).
  • Total flow meter calibration cost works out to 9,332 $ at these inputs, and this is the headline figure for the scenario.
  • Average cost per meter calibrated works out to 389 $ / piece at these inputs.
  • Variable calibration cost works out to 5,832 $ at these inputs.
  • Fixed rig overhead works out to 3,500 $ at these inputs.

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 19.55% below the baseline at 9,332 $.
  • It computes total flow meter calibration cost by adding a wet-cal-weighted variable cost across all due meters to a fixed rig overhead, and reports the blended cost per meter. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total flow meter calibration cost: 9,332 $ (headline result)
  • Average cost per meter calibrated: 389 $ / piece
  • Variable calibration cost: 5,832 $
  • Fixed rig overhead: 3,500 $
