5.2 Measured error
(Liquid/Gas):
3% qG=50% acc.. VDE/VDI 3513 page 2
E/F/A/B (option diff.pressure regulator):
3, 5 % /
5 % FS within 10-100% of the range
5.3 Repeatability
(Liquid/Gas)
1.0 % FS,
E/F/A/B (option differential pressure regulator):
1, 5 % /
2, 5 % FS within 10-100% of the range
5.4
Influence of ambient temperature
none
5.5 Influence of fluid temperature
Deviations in fluid temperature from the temperature observed during calibration can result in a propor-
tional display fault because of the corresponding change in density and viscosity.
6 Conditions of use
The VDI/VDE guidelines must be observed.
The devices can be used for:
-
liquid products that are sufficiently free-flowing, are free of solids, do not bond or do not tend to settle.
-
gases with linear flow behavior and an adequate inlet pressure.
V/N(option differential pressure regulator)
The minimum differential inlet and outlet pressures must be 350 mbar.
