I would like to know what people think about using PID controls on a liquid transfer
to understand what I am asking let me give you a little more information.
I work in a plastic manufacturing plant.
I would like to know what people think about using PID controls on a liquid transfer system.
I have as many as 10 different plasticizers. any one or combination of plasticizers can be used in a recipe.
that vary from a few ounces to 100 pounds of liquid in a variety of combinations.
I need an accurate way of measurement for each material added in a specific amount to maintain a consistency
of my material .
I have an engineering firm recommending a PID control with an elaborate programming scheme.
I am uncertain if these PID controls will stand the test of time. they will be operating in a very harsh dirty environment.
and be service by individuals with minimal service skills or understanding of how they function.
personally I would believe a positive displacement metering device would be more accurate and less prone to damage .
and all I would require to add to my PLC is a high-speed counter and a few simple math calculations.
I would appreciate any feedback or advice on the subject
thank you
