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 direc-
tion, the lug shows the upstream direction and the marked coax cable is connected accor-
ding to fig. 3.3 or 3.4.
8045 with a stainless steel sensor:
The totalizer increases when the arrow on the side of the housing indicates the flow di-
rection, the cable glands show the downstream direction and the marked coax cable is
connected according to fig. 3.3 or 3.4.
For all transmitters, the minimum straight upstream (10 x DN) and downstream (3 x DN) dis-
tances must be observed.
Please ensure that the pipe design does not allow the build up of air bub-
bles or cavities within the medium as this will cause measuring errors.
