Description
Return net fill mass and a symmetric measurement envelope.
Cryogenic measurements and budgets depend on the fluid state, absolute temperatures and pressure reference, as well as compatible units. Local mass, heat or ideal-gas terms describe a supplied model without determining actual material properties or safe equipment operation.
Return net fill mass and a symmetric measurement envelope.
When to use this tool
Use Cryostat Fill Mass Zero Gap when checking a supplied cryogenic measurement, reference-state conversion or engineering budget.
How to use the tool and how it works
- Enter gross, tare, measurementHalfwidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read netMass, lower, upper, zeroInside. Inspect zeroInside before interpreting the associated values.
Return net fill mass and a symmetric measurement envelope. Require measurementHalfwidth >= 0; netMass = gross-tare, lower/upper add minus/plus halfwidth, and zeroInside includes equality at either boundary.1

| Output field | Interpretation | Returned shape |
|---|---|---|
| netMass | Net Mass | Required. Finite number. |
| lower | Lower | Required. Finite number. |
| upper | Upper | Required. Finite number. |
| zeroInside | Zero Inside | Required. Boolean. |

}Limitations and assumptions
- The envelope is supplied, not a calibrated confidence interval; negative net mass is retained.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified state-specific properties and a complete qualified engineering assessment for practical cryogenic design, filling and handling.
