ABSTRACT:
A precision fluid flow regulator for liquid and gaseous applications necessitating reduction of high inlet pressures and requiring precise control of outlet flow rates and pressures. The device includes a large pressure port and a cooperating pressure port closure means having a large pressure sensing area. Embodied internally of the unit is a novel sensing means for accurately sensing outlet flow rates and pressures and for providing instantaneous response to flow rate changes.
