4.12.3. Filter
With the filter settings you adjust the reading of
quickly changing flows. The filter basically averages
the readings from the sensor. More information can
be found in chapter
2.22 Filter Settings.
There are two separate filters that are adjustable and
independent of each other.
Dynamic and Averaging filter:
Dynamic Filter:
The dynamic filter will increase the number of
readings that are averaged when the flow is less
dynamic and decrease the number of readings that
are averaged when the flow shows quick changes. So when the flow is quickly rising or falling it
will take less averages in it calculations. On this way the unit will react faster to changes in the
flow.
Averaging filter:
The averaging filter is a “moving average filter”. It calculates the average value of a number of
measurements and shows the average on the display. As you increase the filter setting from off
to maximum, you increase the number of measurements the average is calculated from.
Before you apply higher filter values, please try to identify the cause of the flow pulsations. This
could be a compressor, pressure amplifiers, incorrectly sized fittings, non-return valves or pressure
regulators. Sometimes creating more “dead volume” before of behind your flow meter could solve
the problem.
