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 mounting hole patterns and sizing are of a multi-variant design which
means that one plate will fit different flange pressure classes e.g. Cl. 150 and Cl. 300.
The flow conditioner and gaskets are fitted between two pipe flange and the flow meter
flange

Use only bolts which match to tehflange bolt hole and this will ensure that the correct positioning
of the plate can be found. The alignment notch must also be pointing in the same plane as the
transmitter.
Incorrect installation of the flow conditioner will have a small effect on the measurement accuracy.

Note!
• 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.
• 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.
• Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the
customer.
