Totalize a batch from a flow-integrator curve

Practice the sequence you already learned for “Totalize a batch from a flow-integrator curve” until the order feels automatic. Drill the process-calculus order from instrument-tech training. The batch ticket is not signed until the integrator is zeroed, the curve is integrated over the window, and the lab check agrees.

1. Zero or note the integrator at batch start.
2. Record the flow signal over the batch window.
3. Integrate flow with respect to time for the total mass or volume.
4. Compare the total to the tank gauge or lab weight.
5. Investigate if the difference exceeds the tolerance.
6. Sign the batch only after the totals agree.
7. Do not use an instantaneous rate as the total.
