Installation; Connection Of The Pulse Transmission Cable2; Specification Of Volumetric Pulse - Sensus PolluFlow Installation And Operating Instructions Manual

PolluFlow can be installed horizontally or vertically
(in rising or down pipes).
PolluFlow is delivered with the integrator mounted
on the flow meter. Depending on the flow meter's
installation position, the integrator can be turned
through steps of 90 degrees. Lift the red spring
catch at the bottom side of the casing using a
slotted screw driver and take the integrator from
the C-rail. Then turn the integrator to the required
position by transposing the C-rail and fasten it
again.
If required, the PolluFlow integrator can be
removed from the flow meter and mounted
separately at a suitable place. The connection
cable can be delivered optionally with a length of
1.5 m or 3 m. Precede as before in order to
remove the integrator. Then unscrew the C-rail
from the bottom and use it as a wall adapter.
Observe following
horizontal installation of meters of qp 15 and
more:
Both ultrasonic transducers inside of the
measuring tube have to be in horizontal
position. Therefore the PolluFlow has to be
installed with the integrator turned upwards
(see fig. 1).
Removed and
integrators have to be installed accordingly
(see fig. 2).
