Fox Venturi Flow Controls fall into these four major categories:
ΔP Venturi Flowmeters: Fox provides custom-built ΔP venturi flowmeters for measuring liquids and gasses in high performance systems, in line sizes below 6″.
Cavitating Venturis: Fox Cavitating Venturies have been used since 1961 to maintain fixed, accurate, repeatable liquid flow rates, unaffected by downstream pressure.
Sonic Chokes/Critical Flow Nozzles: Fox Sonic Chokes are used in dozens of control systems to maintain fixed, accurate, repeatable gas flow rates unaffected by downstream pressure.
Adjustable Area Venturi Valves: Fox Adjustable Area Venturi Valves enable flow rates to be accurately adjusted or regulated, while remaining unaffected by downstream pressure fluctuations.
