6.1 Installation conditions
No special measures such as supports are necessary.
6.1.1 Mounting position
Mounting location
Thermal measuring devices require a fully developed flow profile as a prerequisite for
correct flow measurement. For this reason, please pay attention to the following
points and document sections when installing the device:
• Avoid flow disturbances, as the thermal measuring principle reacts sensitively to them.
• Take measures to avoid condensation (e.g. condensation trap, thermal insulation etc.).
Orientation
The direction of the arrow on the sensor helps you to install the sensor according to the
flow direction (direction of medium flow through the piping).

condensation or contamination.
2) Suitable only for clean and dry gases. If buildup or condensate are always present: Mount the sensor in an
inclined position.
3) Select inclined mounting position (α = approx. 135°) if the gas is very wet or saturated with water.

Installation Proline t-mass A 150 HART
16 Endress+Hauser
Requirement for pipework
The measuring device must be professionally installed, and the following points must
be observed:
• Piping must be professionally welded.
• Seals must be sized correctly.
• Flanges and seals must be correctly aligned.
• The internal pipe diameter on the inlet side must match the internal diameter of the
process connection ordered. The maximum permitted deviation between the internal
diameters is:
1 mm (0.04 in)
• Following installation, the pipe must be free from dirt and particles in order to avoid
damage to the sensors.
Further information → ISO standard 14511
A0005103
Correctly aligned flanges and seals
A0005105 A0005106 A0005104
Incorrectly sized seal Incorrectly aligned flanges and seals Internal diameter of pipe does not

Installation Proline t-mass A 150 HART
18 Endress+Hauser
This is a special Endress+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.
Pressure loss
The pressure loss for flow conditioners is calculated as follows:
Dp = K g2
rD4

A0005243
∆p = Pressure loss [mbar]
ρ = Density [kg/m3]
K = Constant 1876 (SI units) or 8.4 · 10-7 (US units)
 = Mass flow [kg/h]
D = Diameter [mm]

Calculation example
•  = 412 kg/h
• ρ = 8.33 kg/m3 at 7 bar abs. and 20 °C (68 °F)
• D = 42.8 mm for DN 40, PN 40
Calculation in SI units
∆p = 1 876 · (4122 ¸ 8.33) · (1 ¸ 42.84) = 11.4 mbar
