Flow control valve with integral sensor and controller and related method

摘要: A flow control valve assembly, and a method of determining controlling fluid through the valve, that is relatively simple in design, inexpensive, accurate, has wide measurement range. The (100) compact includes all components single, assembly. Such may include differential pressure sensor (124), (122), temperature (120), position (118), processor (116). senses across variable area orifice (110). within (108) supplies signal. (120) receives signal, signal uses these signals to determine parameter passageway (102).
