Installation Guidelines
The suitable pipe size is selected using the
diagram on the end pages.
The pipe must be completely filled with the
fluid, i.e. air bubbles must not be present.
The device must be protected from constant
heat radiation and other environmental
influences, such as direct exposure to
sunlight.
Do not mount behind turbulence generating
fittings (elbow, valves, T-pieces, etc.). The
minimum upstream 10xD and downstream
3xD distances must be observed.
According to pipes design, necessary
distances can be larger or use a flow
tranquilizer to obtain the best accuracy.
Fore more informations, please refer to EN
ISO 5167-1.

3.2 Installation
The flow sensor 8020 can be easily installed
in pipes using our specially designed fitting
system.
1. The fitting 4 must be installed into the
pipe according to the installation
specifications in section 3.1.
2. Insert plastic nut 3 into fitting, and let
plastic ring 2 snap into guide bush 5.
3. Carefully insert sensor 1 into fitting. If
installed properly, the transmitter cannot
be rotated.
4. Tighten transmitter housing to fitting with
plastic nut 3.
CAUTION! Plastic nut must only be
tightened by hand!
