Vortex meters require a fully developed flow profile as a prerequisite for correct volume flow
measurement. Therefore, please note the following:
Orientation
Recommendation
Compact version
Remote version
A Vertical orientation (liquids)
A0015591
1)
A Vertical orientation (dry gases)
A0015591
A0041785
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!
2)
Danger of electronics overheating! If the fluid temperature is 侒 200 °C (392 °F), orientation B is not
permitted for the wafer version (EF200W-C) 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) 侒 200 °C (392 °F): orientation C or D
4)
In the case of very cold media (e.g. liquid nitrogen): orientation B or D
