Cathodic Protection
Display a pipe-to-soil reading with an optional labeled reference correction.
App id: MEAS-03. Reference version 1.0.
How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Vpipe-soil = Vmeasured + VcorrectionInputs
| Name | Unit |
|---|---|
| Measured potential (camera) | mV |
| Reference correction (optional) | mV |
| Selected criterion (optional) | mV |
Outputs
| Name | Unit |
|---|---|
| Pipe-to-soil potential (hero result) | mV |
| Selected criterion | mV |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Correction defaults to zero. Criterion defaults to −850 mV when left blank.
- Context is not a protection verdict. Polarization, IR drop, and electrode type still matter.
Provenance
- −850 mV CSE is a common CP reference, not a Fieldeng pass/fail. Correction is applied only when entered.
