4.1 Location
To ensure the optimum function of measuring equipment it is important that the installation
instructions are followed closely, point by point.
The flowmeter can be located both indoors and outdoors, but the following conditions must be
observed:
Liquid temperature: -58 to 356°F (-50 to +180°C).
The grade of enclosure can be choosen from
IP 20 up to IP 67.
When the temperature difference between a
liquid and the surroundings is large, the sen-
sor must be insulated to prevent 2-phase flow
and thereby measuring inaccuracy. This ap-
plies especially in the case of low flow.
Important!
The sensor must always be completely filled with a homogeneous liquid or gas in single
phase, otherwise measuring errors will occur.
4.2 Cavitation Avoid cavitation in the system, i.e. sucking in or
releasing air into the system, because this may
produce errors.
Static back pressure minimum 0.1 - 0.2 bar.
4.3 Air bubbles Avoid large quantities of air collecting in the
sensor because these will disturb measure-
ment. Homogeneous mixtures of air and sol-
ids, however, will not disturb measurement.
When there is air in the liquid, installation of an
air trap ahead of the meter is recommended.
If there is air/gas in the liquid or liquids which
are volatile, horizontal sensor mounting is
recommended.
4.4 Mounting The unit must be mounted on a flat wall or steel
frame (vibration-free).
