TOTALIZER

Scan-rate-independent flow or energy totaliser with a declared rate time base, low-flow cutoff and reverse-flow handling.

Validated application blockProcess ControlIEC 61131-3v1.0.0

When to use it

Use TOTALIZER when a rate has to become a quantity — flow into volume, power into energy, current into amp-hours — for billing, for a water or energy balance, for a batch, or for a cycles-of-concentration calculation.
