System pressure
It is important to ensure that cavitation does not occur as it could influence the oscillation of the
measuring tube. No special measures need to be taken for fluids which have properties similar to
water under normal conditions.
In the case of liquids with a low boiling point (hydrocarbons, solvents, liquefied gases) or in suction
lines, it is important to ensure that pressure does not drop below the vapor pressure and that the
liquid does not start to boil. It is also important to ensure that the gases that occur naturally in many
liquids do not outgas. Such effects can be prevented when system pressure is sufficiently high.
Consequently, it is generally best to install the sensor:
• On the pump pressure side (no risk of vacuum)
• At the lowest point in a riser

Orientation
Make sure that the direction of the arrow on the nameplate of the sensor matches the direction of
flow (direction in which the fluid flows through the pipe).
Vertical/horizontal:
When installed correctly, the transmitter housing is above or below the pipe. This arrangement
means that no gas bubbles or solid deposits can accumulate in the curved measuring tube (single-
tube system).
Do not install the sensor in such a way that it is suspended in the pipe without support or measures
to secure it. This prevents excessive material strain at the process connection. The base plate of the
sensor housing is designed for mounting on a tabletop, wall or post.
