Installation with elbows, pumps or valves
To avoid a vacuum and to maintain the specified level of accuracy, if possible install the
device upstream from assemblies that produce turbulence (e.g. valves, T-sections) and
downstream from pumps.
Maintain straight, unimpeded inlet and outlet runs.

Installation without inlet and outlet runs
Depending on the device design and installation location, the inlet and outlet runs can be
reduced or omitted entirely.
Maximum measurement error
When the device is installed with the inlet and outlet runs described, a maximum
measurement error of ±0.5 % of the reading ±2 mm/s (0.08 in/s) can be guaranteed.
Devices and possible order options
Order code for "Design"
Option Description Design
C Fixed flange, constricted measuring tube, 0 x DN
inlet/outlet runs
Constricted measuring tube
1)
1) "Constricted measuring tube" stands for a reduction of the internal diameter of the measuring tube. The
reduced internal diameter causes a higher flow velocity inside the measuring tube.
Installation before or after bends
Installation without inlet and outlet runs is possible: devices with the order code for
"Design", option C.
