Average and Limit
Sudden changes in the flow rate and closely spaced pulses can cause wide variations in the
calculated flow rate.
Averaging the flow over a number of samples reduces the large variations. Together with the
average setting, the limit value affects the way the calculated flow rate is determined. If the flow just
calculated is outside the limits specified, the current flow rate is updated immediately to the new
value, without averaging.
Together, the flow meter uses the average, limit and time to calculate the current flow.
Trigger Value
The setting adjusts the flow rate (in l/m) at which the flow meter will become triggered.
Allocated Flow Meter
Any switch input on the main screen panel or digital input module in an Expansion Module position
can be selected as the input for the flow meter.
Update Rate
This setting only affects flow meters using a digital sensor as an input. Flow Meters using a switch
input on the main screen are updated every second and pulse. This setting adjusts the period of time
between updates to the calculated flow rate.
Total Flow and Current Flow Rate
The total and current items show the real time total flow and current flow rate for the flow meter.
They are updated every second for any change. These values are shown on the edit screen for quick
reference and ease of operation.
Note that the total flow and current flow rate use the current saved values for the flow meter. For
example, if the calibration value is changed, the change will not be reflected in the total flow or
current flow rate until the accept button is pressed.
