Static pressure is the line pressure (gauge or absolute) at
the high port when measuring a differential pressure.
Static pressure affects the DP measurement (with current
technologies) at pressures greater than 1,000 psig (69barg).
Some commercial DP transmitters (Honeywell and Yokogawa)
use an absolute pressure sensor sensing the high side port
pressure which is used to correct for static pressure error
when static pressure is greater than 1,000 psig.
A separate calculation for static pressure error is provided
for DP transmitters (by the major vendors) as part of a
total uncertainty calculation.
Multivariable transmitters (a DP transmitter with a
temperature sensor and an absolute static pressure sensor)
use the same technique of measuring (absolute) static line
pressure for calculating inferred mass flow for gases.
