Installation Proline t-mass A 150 HART
18 Hauser
This is a special Hauser design which was developed for the sensor t-mass A 150
(DN 40 to 50 / 1 ½ to 2"). The arrangement of the individual screw holes and their
diameter means that the flow conditioner can be used for different flange pressure ratings.
The flow conditioner and the seals are installed between the pipe flange and the
measuring system. To ensure correct centering of the flow conditioner, use only standard
screws which match the screw holes .
Please note that the flow conditioner must be mounted in such a way that the alignment
notch is pointing in the direction of the transmitter. Incorrect installation could have a
negative effect on the measurement accuracy.

• Not suitable for lap joint flange or threaded versions!
• Order the sensor and the flow conditioner together to ensure that they are
calibrated together. Joint calibration guarantees optimum performance. Ordering
the flow conditioner separately and using it with the device will further increase
measurement uncertainty.
• The use of flow conditioners from other suppliers will affect the flow profile and
pressure drop and will have an adverse effect on performance.
• Screws, nuts, seals etc. are not included in the scope of supply and must be provided
by the customer.
