Weigh Scale Dosing (P_DoseWS)

ingredient addition that uses a weigh scale to measure the quantity of ingredient
added. The weigh scale can be on the receiving vessel (gain in weight) or on the
sourcing vessel (loss in weight). The weigh scale can be connected via an analog

Guidelines
Use this instruction in these situations:
• You want to control basic dosing (ingredient addition) with basic features,
such as bulk/dribble rate selection, preact, automatic preact adjustment,
and the ability to start, pause, and resume flow.
• You are measuring the quantity of ingredient added to a destination vessel
