摘要： A process device providing total fluid flow control is provided. The device includes a closure mechanism disposed in a flow conduit. The closure mechanism, which is preferably an iris-type diaphragm, provides a variable internal diameter. The device includes a differential pressure sensor for sensing the differential pressure on opposite sides of the diaphragm. A controller receives an indication of differential pressure and generates a control signal to an actuator that actuates the closure mechanism. The closure mechanism, differential pressure sensor and controller create a closed-loop flow controller in a single process device.
