As I do not know what the tool is called to enable me to program this function, I need to ask this question:
1) I am using a DAQ with 9203 8-channel mA Module
2) I am converting the output of this module to gal/min through a FORMULA tool to represent gallons/min
3) At the START of an event, I need to read the gallons/min 10x/sec and on each read, create an accumulation of flow to calculate VOLUME since the event started.
4) Every second, I need to update an indicator with this VOLUME total until the event STOP is pressed.
I do not need help with the coding, just the names of the tools I should use. I would hate to do some elaborate gyrations to find out later that there is a tool already to do this.
It sounds like you want a shift register to store the accumulated volume from one iteration of the loop to the next. You would just add to the shift register the new rate in gals/min x the loop rate 1/10 second (also some time conversion factors).
