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. 'Labview Based PID Controller For Cylindrical Tank Level. This video demonstrates how to set up LabVIEW software and LabVIEW DAQ cards for closed loop flow control using an Equilibar valve. The advanced PID algorithm combines all of the features of the PID VI algorithm, plus. Section 4 includes description about tuning of PID to get.

The end-user must develop the LabVIEW instrument file.ĭetails for setting up LabVIEW with Equilibar Flow Control Valve LabView based PID VI, Hardware implementation, signal conditioning and programming in LabView. On-site personnel can tune the PID settings in the program to optimize the valve’s performance for each application. 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 this page you will find specific information about using LabVIEW as a PID controller for a flow control loop with an Equilibar FCV.īelow is a schematic showing how the system is generally set up.

Water Hammer and Chatter with Equilibar Back Pressure RegulatorsĮquilibar 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.įor 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 ” page. 33 PID Control Tutorial: Control and Simulation in LabVIEW 5.2 Auto-tuning The LabVIEW PID and Fuzzy Logic Toolkit include a VI for auto-tuning.
