Using a mass flow meter for automatic fast-fill batching — Part II
This two-part article describes how a fast-fill automatic batching system differs from more traditional loss- and gain-in-weight systems and how the fast-fill system works in terms of a predictive system error equation. Part I appeared in September.
The feeder error equation is useful for determining how to improve the fast-fill system's performance but should be used only to estimate feeder error. This is because unlike meter error, which can be precisely calculated based on the meter manufacturer's quoted accuracy, feeder error is less well defined.
