Feedback Conversion - Danfoss VLT AQUA Drive FC 202 Design Manual

Introduction

2.8.6 Feedback Conversion

In some applications it could be useful to convert the
feedback signal. One example is using a pressure signal to
provide flow feedback. Since the square root of pressure is
proportional to flow, the square root of the pressure signal
yields a value proportional to the flow. For an example,
see Illustration 2.14.
