Would i use an accumulator for volume flow

[rhawk]

I have a situation where there is a flow meter that shows the water flow per gallons, in realtime,

The water flows only when a certain pump starts. The flow may start at 600 gpm while starting to fill a tank and then go down to 200 gpm when the tank starts to get full.

Could, and how, would i use an accumulator to track the total number of gallons that flows through the pipe?

When the pump starts i do have a register in the PLC that i can monitor to tell if pump is running. Would i need this or just use the accumulator to sum the actual values coming from the flow meter?

thanks

Use the Integral object

Set the flowrate in the Input, update should be whenever you want to display the change (I uses 1\3 second).
Time unit should be based on the the totlizing requirement (01:00= 1 minute)

Good luck
