Flow direction
Horizontal flow direction
Vertical flow direction
The measuring principle is independent of the flow profile as long as tur-
bulence does not extend into the measurement zone, e.g. downstream
from double elbows (1), in case of tangential inflow or where gate valves
are partially open upstream of the sensor.
In these cases, measures must be taken to normalize the flow profile.
•
Do not install fittings, elbows or valves, etc. directly upstream of
the sensor (1).
•
Flaps must be installed so that the flap blade does not extend into
the sensor.
•
Valves or other shut-off devices should be mounted in the outlet
section (2).
Experience has shown that a straight inlet section of 3 × DN and a
straight outlet section of 2 × DN is sufficient in most cases (DN = nom-
inal width of the transmitter – see the adjacent figure).
For test stands, the reference conditions of 10 × DN for the straight inlet
and 5 × DN for the straight outlet must be provided according to EN
29104/ISO 9104.

Measuring pipe must always be full.
•
Ensure the line is slightly inclined for degassing.
