Outlet runs with pressure measuring points
The pressure measuring point should be installed downstream of the measuring device, so that there
is no potential influence of the pressure transmitter process connection on the flow entering the
measuring point.

Perforated plate flow conditioner
It is recommended to install a perforated plate flow conditioner if the recommended inlet runs are
not available. See accessories ä 87.

Flow conditioner for use with insertion sensors
The well known "Mitsubishi" design is recommended for this application DN 80 mm (3") to
DN 300 mm (12"). The flow conditioner must be installed at a distance of 8 × DN upstream of the
sensor. A further 5 pipe diameters inlet run is required upstream of the actual conditioner itself.
