6.1.4 Installation position
Rotamass Total Insight Coriolis mass flow and density meters can be mounted horizon-
tally, vertically and at an incline. The measuring tubes should be completely filled with the
fluid during this process as accumulations of air or formation of gas bubbles in the mea-
suring tube may result in errors in measurement. Straight pipe runs at inlet or outlet are
not required.
Sideways position
The sideways position must be avoided when installing the flow meter, because this may
result in a deterioration of accuracy.

Horizontal
installation
▶ In case of fluids, install the measuring tubes downward so as to avoid gas accumula-
tion in case of a low flow rate.
▶ For gas applications, install the measuring tubes upward so as to avoid fluid accumu-
lation in case of a low flow rate.
