Amcaremed flow gauge regulators are the pressure-reducing device that can depressurize the high-pressure gas in the cylinder. It can maintain a stable outlet pressure under changing operating conditions of input pressure and output flow. Flow gauge regulator suitable high pressure, usually applying to anesthesia apparatus, respirator, and other medical gas equipment. Diaphragm and maternal adopt hard seal form. Maximum inlet pressure is 3000 psi. The flow gauge regulator has two dials that show gas flow and inlet pressure.
