3.2 Installation conditions
Note the following points:
• The measuring device requires a fully developed flow profile as a prerequisite for correct volume
flow measurement. The inlet and outlet runs must be taken into account (see Page 14).
• The maximum permitted ambient temperatures (see Page 63) and fluid temperatures
(see Page 63) must be observed.
• Pay particular attention to the notes on orientation and piping insulation (see Page 12).
• Verify that the correct nominal diameter and pipe standard (DIN/JIS/ANSI) were taken into
account when ordering since the calibration of the device and the achievable accuracy depend on
these factors. If the mating pipe and the device have different nominal diameters/pipe standards,
an inlet correction can be made via the device software by entering the actual pipe diameter (see
MATING PIPE DIAMETER function on Page 97).
• The correct operation of the measuring system is not influenced by plant vibrations up to 1 g,
10...500 Hz.
• For mechanical reasons, and in order to protect the piping, it is advisable to support heavy sensors.
For weight information, please refer to Technical Information TI070D/06/en.
3.2.1 Dimensions
The dimensions and lengths of the sensor and transmitter can be found in the Technical Information
TI070D/06/en.
3.2.2 Installation location
We recommend you observe the following dimensions to guarantee problem-free access to the
device for service purposes:
• Minimum spacing in all directions = 100 mm
• Necessary cable length: L + 150 mm

3.2.3 Orientation
The device can generally be installed in any position in the piping.
In the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (see
orientation A).
In the case of hot fluids (e.g. steam or fluid temperature
≥
200 °C), select orientation C or D so that
the permitted ambient temperature of the electronics is not exceeded. Orientations B and D are
recommended for very cold fluids (e.g. liquid nitrogen) (see Page 13).
