Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor
according to the flow direction (direction of medium flow through the piping).
Vortex meters require a fully developed flow profile as a prerequisite for correct volume
flow measurement. Therefore, please note the following:
Orientation Compact version Remote version
A Vertical orientation
A0015545
1)
B Horizontal orientation, transmitter head up
A0015589
2) 3)
C Horizontal orientation, transmitter head down
A0015590
4)
D Horizontal orientation, transmitter head at side
A0015592
1) In the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (Fig. A).
Disruption in flow measurement! In the case of vertical orientation and downward flowing liquid, the pipe
always needs to be completely filled to ensure correct liquid flow measurement.
2) Danger of electronics overheating! If the fluid temperature is ≥ 200 °C (392 °F), orientation B is not
permitted for the wafer version (Prowirl D) with nominal diameters of DN 100 (4") and DN 150 (6").
3) In the case of hot media (e.g. steam or fluid temperature (TM) ≥ 200 °C (392 °F): orientation C or D
4) In the case of very cold media (e.g. liquid nitrogen): orientation B or D
The "mass" sensor version (integrated pressure/temperature measurement) is
available only for measuring devices in the HART communication mode.
