Instruction Manual
DM08
Basically, the measuring principle does not depend on the flow profile. You should use
straight inlet and outlet sections according to the nominal width (DN). An inflow path of 5 x
DN and an outflow zone of at least 2 to 3 x DN is required.
The flow sensor is only suitable for application in completely filled pipe systems. With a free
pipe outlet, the sensor should not be installed in pipe sections that could run empty (e.g.,
downpipes).
If the sensor must be installed in a down pipe, ensure that portion of the pipeline is always
filled 100% with the media.
Due to possible accumulation of gases, the sensor should not be installed at the highest
point of a pipeline.
It must be ensured, that the axes of the electrodes are running horizontally to avoid erro-
neous measurements due to deposits or air bubbles on the electrodes.
Also, note that in case of deviations from horizontal, the functioning of the Empty pipe de-
tection (p. 9) is limited.
