3.1 Installation Guidelines

The flow transmitter 8025 can only
!
be used to measure pure, liquid and
water ressembling fluids (solids content ≤ 1
%, viscosity max. 300 cSt with on-line
calibration).
Installation Guidelines
The pipe must be completely filled with the
fluid, i.e. air bubbles must not be present.
The device must be protected against
constant heat radiation and other
environmental influences, such as direct
exposure to sunlight or magnetic fields.
Do not mount behind turbulence generating
fittings (elbows, valves, T-pieces, etc.).
Observe the minimum upstream 10 x D
and downstream 3 x D distances.
(For further informations, please refer to EN
ISO 5167-1).
