Weighing, Dosing & Loss-in-Weight Feeding calculators

Check dosing performance with actual masses, timed catches, recipe requirements and equipment limits.

What this hub covers

  • Measured feed rates, dose error, hopper refills, screw speed, scale resolution and ingredient mass balances.
  • Browse weighing, dosing & loss-in-weight feeding calculators for manufacturing planning, quoting, quality, capacity, and operations decisions.

Best calculators in this category

  • Measured Feeder Rate: Measure feeder mass flow from a timed catch test.
  • Signed Dosing Error: Compare a weighed dose with its recipe target.
  • Hopper Refill Interval: Estimate the time available between hopper refill phases.
  • Batch Weight Tolerance Window: Check a batch weight against a symmetric recipe tolerance.
  • Ingredient Mass Variance Cost: Value the difference between actual ingredient consumption and the recipe quantity.
  • Loss-In-Weight Catch Test Calibration: Compare a loss-in-weight controller total with an independent catch weight.
  • Gravimetric Versus Volumetric Feed Delta: Compare a fixed volumetric setting with a required mass-flow setpoint.
  • Microingredient Usage: Calculate recipe microingredient demand from a mass concentration.
  • Feeder Running Time Utilization: Measure how much scheduled time a feeder actually spends feeding.
  • Two-Ingredient Recipe Cost: Cost a recipe containing one additive and one base ingredient.
  • Scale Display Resolution: Compare a scale’s displayed increment with the dose you need to weigh.
  • Refill Feed Interruption Time: Quantify actual feed interruptions associated with hopper refills.

Category questions

  • Where should my feeder inputs come from? Use timed catch tests, net mass readings, recipe requirements, recorded refill interruptions and qualified equipment limits. The example values are illustrative.
  • Does scale readability establish dosing accuracy? No. Readability is the smallest displayed increment. Calibration, repeatability, vibration, tare and the complete dosing process determine whether a weighing method meets your requirement.
  • Does every hopper refill count as downtime? No. Many loss-in-weight feeders continue feeding volumetrically during refill. Enter only measured intervals with no feed when calculating refill interruption time.
  • Can I save a recipe or catch test in Excel? Yes. The calculator workbook includes editable inputs, live formulas and method notes. Retain the material condition, scale range and test timestamps with the calculation.
