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 DN
and downstream 3 x DN distances.
