10.2.10 Inlet and outlet sections
Inlet and outlet straight are not required on a linear flow profile of the fluid. For an extremely non-linear flow profile (e.g. shut-off/control
valves are located at the meter inlet), we recommend an inlet section with a mounting length of 250 mm (see also guidelines in
accordance with VDI/VDE 3513).
10.2.11 Physical state
Liquid or gaseous
10.2.12 Density
Liquids: up to 2.0 kg/l
Gases: no restrictions
10.2.13 Viscosity
The influence of viscosity depends on various factors. Therefore, it must be calculated for each application.
10.2.14 Pressure (for gas measurement)
The measured values only apply to the calibrated fluid data stated on the scale. Any change or deviation in pressure will cause a
display fault.
10.2.15 Pressure loss
Depends on the meter size and the measuring range (see measuring range table page 6).
