FLOW DETAILS TAB

FLOW RATE:

  

This is the instantaneous flow rate and is updated approximately every 
100 milliseconds.

FILTERED

 

This is the filtered flow rate and is identical to the LCD display on the 

FLOW

 

flowmeter (if fitted) and the speed of change will depend on the filter 

RATE

 

setting. The filter will also affect the response time for the analogue 

 

outputs and the flow switches.

TOTAL:

 

The total liquid passed since the last reset.

PIN 6 & 7:

 

 If no selection is made “Not used” will be in the Notes column. See 
following text and chart for the display legends.

 

 OR:- When Pin 6 or 7 is set to “Output” and set to “Pulse” this will 
display the frequency of the running output and the number of pulses 
per litre selected.

 

 OR:- If it is selected to “Output” and set to “Flow switch” the Value 
column will show the transistor status either “low” or “high” and the 
notes will show the selected switch points.

 

 OR:- If “Output” and “Reverse Flow” are selected the Value column will 
show either “low” or “high” depending on forward or reverse flow.

 

 OR:- If “Input” is selected the Value column will show “high” or “low” depending 
on the switch condition and “Input Logic level” in the Notes column.

The large display reflects the meter readings showing on the Atrato LCD Display, if fitted 
and will mimic that display. The buttons either side have the functions selected on the 
‘Configuration’ screen and also work in parallel with the buttons on the Atrato flowmeter 
unit itself. The small window below the rate and total display shows various relevant 
operational parameters whilst the unit is operating e.g. relay status and frequency 
output if these options are selected; and overfill or under fill if in batch mode.
