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.

The figure above illustrates the minimum recommended inlet and outlet runs expressed in multiples of the pipe diameter
using a flow conditioner.

Flow conditioner for use with insertion sensors 65I
The well known "Mitsubishi" design is recommended for this application DN 80 mm to
DN 300 mm (3" to 12"). The flow conditioner must be installed at a distance of 8 × DN
upstream of the sensor. A further 5 pipe diameters minimum inlet run is required upstream
of the actual conditioner itself.
Measured errors can occur depending on disturbances in the inlet run. Therefore it is advis-
able to choose inlet runs that are as long as possible.
!
Note!
In the case of insertion devices, the inlet run selected downstream of the conditioner should
be as long as possible.
