Burkert 8045 Mode D'emploi page 57

Mounting direction and flow measuring:
The flow value displayed by the transmitter is positive whatever the mounting direction
of the device, but the totalizer increases or decreases depending on several
parameters,i.e.:
8045 with a PVDF sensor:
The totalizer increases when the arrow on the side of the housing indicates the
flow direction, the lug shows the upstream direction and the marked coax cable
is connected according to fig. 3.3 or 3.4.
8045 with a PVDF sensor:
The totalizer increases when the arrow on the side of the housing indicates the
flow direction, the cable glands show the downstream direction and the marked
coax cable is connected according to fig. 3.3 or 3.4.
The minimum straight upstream (10 x DN) and downstream (3 x DN) distances
must be observed.
Please ensure that the pipe design does not allow the build up of air
bubbles or cavities within the medium as this will cause measuring errors.
