Perfect Flow Control is achieved through two critical steps that should be performed in a precise sequence. The first step is to tune the resistance of your system. The second critical step is to tune the flow control parameters.

Elveflow Flow Rate Control is achieved through a control loop. Basically, a control loop is a system where a feedback mechanism is used to control a certain action. In many electronic devices, a software algorithm called PID is often used to control these systems. PID is an acronym that stands for Proportional, Integral, and Derivative. Its general principle is beyond

the scope of this document, but the principle of this tuning is to find good parameters to end up with a sensor reaction type (fast reaction, stable reaction, etc…) that fits your needs. Let's see how this PID regulation is used in Elveflow ESI software.

The MFS User Guide will give you useful context information and practical details about how to proceed to flow control tuning.
