Low Flow Gas Regulator

 

Find Suppliers by Category

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only.

    . In particular, the design enables revolutionary performance for low flow rates of gas (<10 std cm3/min). In sonic mode, the capability for accurate control is > +-1.0% of reading over a 10:1 dynamic range with repeatability exceeding +-0.2% of reading (see Figures 7 and 8). For a full-scale flow rate
