how to set PID control in VFD that operate a centrifuge pump transporting juice being concentrated 1

[systemsaver]

Dear engineers
I have a customer that is using a Siemens VFD manually to operate a centrifugal pump that transports juice with different Brix grade and the only reason he is using the VFD is for the start of the pump and is not getting a benefit of the affinity law to save energy running the pump.
Would someone help to set up a PID control for the VFD?
I would appreciate very much any help you can provide us
Thank you.

Sure LittleInch. We will share the data in this forum.

You probably realize this but the data should be correlated with the viscosity.

Not just a good idea;
It's the LAW!
