What is temperature compensation? How is temperature used in
instrumentation?

Answer:

Temperature compensation is an adjustment to instrument
readings to account for known physical changes due to
temperature.

Temperature and pressure compensation to a differential
pressure measurement can produce an inferred mass flow rate
measurement, rather than a volumetric flow rate.

Most high end instruments have internal temperature
compensation that affects the measurement that is reported,
for instance, DP transmitters measure pressure body
temperature and electronic body temperature.

Fuel storage tanks will measure temperature gradient from
the top to the bottom of a tank and calculate volume and
mass adjustments accordingly, for inventory purposes.

Thermal dispersion flow meters adjust their flow rate
calculations according to the flow medium's temperature.
