ECPVA Forward Differential Pressure Log
Margin = catalogue maximum differential pressure minus recorded forward differential pressure, at the two catalogue temperatures only.
Catalogue margin (comparison only)
bar
Temperature must be exactly20°C or80°C. Positive/zero margin only compares a catalogue number; it is not approval of the fluid, housing, seals, pressure transients or installed assembly. A negative margin exceeds the listed maximum. All other temperatures, reverse flow and steam require technical confirmation; no interpolation. Replace example inputs with actual readings.
