Equilibar valves function as back pressure regulators by design and can be set up and used in flow control applications using a flow meter and control logic as explained on our flow control page.<\/a> <\/p>

For a review of the various types of control systems you can use to set up an Equilibar FCV for flow control, please visit our “ getting started with flow control<\/a> ” page.<\/p>

On this page you will find specific information about using LabVIEW as a PID controller for a flow control loop with an Equilibar FCV.<\/p>

Below is a schematic showing how the system is generally set up. Use the LabVIEW program on the laptop to send signals between I\/O control boards, the flow meter and the Equilibar electronic pressure regulator. On-site personnel can tune the PID settings in the program to optimize the valve’s performance for each application. The end-user must develop the LabVIEW instrument file.<\/p>

Details for setting up LabVIEW with Equilibar Flow Control Valve<\/h3>

This video demonstrates how to set up LabVIEW software and LabVIEW DAQ cards for closed loop flow control using an Equilibar valve. The LabVIEW DAQ cards receive a signal in from an Endress + Hauser flow meter, processes it through a PID loop in the LabVIEW software, and send the signal out to a QPV electronic pressure regulator which pilots the Equilibar flow control valve.<\/p>
