Setting the low-flow cut-off In certain applications flow signals are not required below a given flow. In this menu a
0 to 10% cut-off of the maximum flow can be selected. By default the meter is set to 1.5%.
Setting the empty pipe limit If detection of an empty pipe or of a density value is needed, it can be set under this menu option.
If the set density value is measured this will activate a relay or the digital output. In addition will
be recorded in the error log.
Setting the noise filter
The instrument carries out signal processing internally using a patented FFT (Fast Fourier
Transformation) algorithm. This technology allows noisy sensor signals to be filtered. For
example, if the instrument is exposed to a strongly pulsating flow, varying pumping frequencies
or strong pressure gradient, etc. this can in certain cases result in noise on the pick-up signals,
with measurement error as a result. This measurement error can be reduced by increasing the
filtration under the menu option noise filter. Setting 5 represents the maximum possible filtration
and setting 1 represents the minimum possible filtration.
Setting the error level The instrument contains a particularly informative error monitoring system that the user can
configure according to need. The system is described in more detail in the section on error
handling.
Setting the totalizer The instrument is equipped with two independent totalizers that can be set for totalizing mass flow,
fraction A, faction B or volume.
Forward: only flow in a positive direction is totalized.
Reverse: only flow in a negative flow direction is totalized.
Net: the total net flow is measured.
