Board Level Controllers – Best of Both Worlds

Submitted by Nathan Ehresman || Valin Corporation

An operator in a fluid handling process is only as effective as his ability to work with a given controller. If there are factors that keep this individual from doing what is necessary for a smooth operation, adjustments need to be made.
