Calculating the average flow
To calculate the average flow wait for the allotted monitoring period to expire then divide the indicated total flow
by the time taken. This will give you the average flow in m/s, galls/hours or whatever units you select.
Note that in a bi-directional flow situation you must calculate the difference between the indicated positive and
negative flow totals before carrying out the average flow rate calculation.
How to stop the totaliser temporarily
If you want to stop the totaliser temporarily for operational reasons, set the Totaliser option to Stall in the FLOW
READING OPTIONS screen as described above. This will stop the totaliser operation without affecting its current
values.
