Repeatability
(Liquid/Gas)
1.0 % full-scale,
V / N (optional differential pressure regulator):
Measurement / regulator deviation:
1.5 % /

6.4
Influence of ambient temperature
none
6.5
Influence of fluid temperature
Deviations in fluid temperature from that of the temperature observed during calibration can result in a
proportional display fault because of the corresponding change in density.
Temperature-related changes in viscosity will cause a non-linear display fault.
