Video demonstrates new way to control flow over wide range of flow rates

A video recently filmed in the Equilibar laboratory demonstrates a new method of maintaining consistent flow control over a wide range of flow rates–typically 100:1. This is accomplished by using an Equilibar® back pressure regulator with a pilot pressure controller and a flow meter in a PID (proportional-integral-derivative) control loop. This approach is especially useful Read More
