Hello Ebsilon users! I found an interesting new component in the v16 release notes: the Comp 168 Quantity Converter. It looks similar to the Comp 36 Transmitter (a big arrow with a logic line in and out).
If you attach it to a pipe, you can pick any of 142 quantities (yes, I counted them!) to send to the logic line leaving. You can choose up to 3 such quantities... they'll replace the M-P-H values on the logic line. This allows you to use controllers to control many more properties.
Here's a screenshot where I'm pushing Cp, entropy, and dynamic viscosity.
