Differential-Pressure Evidence Triage

Compare two differential-pressure readings in the same unit and choose which operating evidence to collect. This tool sets no replacement threshold.

Observed operating data

Clean/baseline differential pressure (bar)

Current differential pressure (bar)

Flow relative to the baseline reading

Operating phase

Observed change and review path

Enter both readings and their operating context.

Collect with the readings

Actual flow, temperature and gauge locations
Contaminant analysis, sample timing and particle loading
Housing seals, bypass condition and installation record
Change-out history and the approved product/housing operating limits

Send the pressure and operating history

Ratio = current DP ÷ baseline DP. Change = (ratio − 1) × 100%. These are arithmetic comparisons, not temperature/flow corrections or evidence of removal efficiency. Follow the approved plant operating and change-out procedures.
