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 (35 hole) for use with insertion sensors
The well known "Mitsubishi" design is recommended for this application DN 80 mm (3") to DN
300 mm (12"). For the majority of gas types, the flow conditioner must be installed at a distance of
10 x DN upstream of the sensor. A further 5 pipe diameters inlet run is required upstream of the
actual conditioner itself.
Flow conditoner (19 hole) for use with flanged sensors
This is a special Hauser version designed specially for use with the t-mass F sensor (Sizes
DN 25 to 100 /1" to 4"). The flow conditioner should be fitted immediately upstream of the flanged
sensor. A further 5 pipe diameters inlet run is required upstream of the actual conditioner itself.
For optimum performance, it is advised that the t-mass F sensor and flow conditioner are ordered
at the same time such that they are calibrated together. To retrospectively fit a flow conditioner will
have a small effect on the measurement performance.
!
Note!
The use of other types of flow conditioners, other than the Hauser flow conditioner, with
the t-mass F sensor will have an impact on the measurement performance due to the effects of flow
profile and pressure drop.
