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.
Warning
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.

Resolution
The RedyCompact has the ability to show the actual flow in many different engineering units. This
means that the number of digits in the readout can change a lot. In automatic resolution mode the
required number of digits is automatically calculated depending on the range and selected units.
This resolution is however adjustable by the user.
In this menu you can adjust the resolution of your flow and totalizer values
shown on the display.
The RedyCompact has the ability to show the actual flow and the totalizer
in many different engineering units. This means that the number of digits
in the readout can change a lot. In automatic resolution mode (menu
option "Auto") the number of digits are computed depending on range and
current selected unit.
The minimum number of digits is 4, the maximum 6 (Excluding the
decimal point). Below you find the table on how many digits will be visible
in this auto mode.
