Systems and methods for managing pressure and flow rate

A device for managing pressure and flow rate of a fluid comprising:

• a first orifice plate having one first orifice, the one first orifice having a first diameter (d1), the one first orifice positioned near an edge of the first orifice plate;
• a second orifice plate having one second orifice, the one second orifice having a second diameter (d2), the one second orifice positioned near an edge of the second orifice plate;
• and
• a tubular structure having an effective diameter (D) comprising the first orifice plate and the second orifice plate placed at perpendicular direction to the fluid flow within the tubular structure, separated by a distance (X),
• wherein the pressure and/or the flow rate downstream of the device are lower than the pressure and/or flow rate upstream of the device and wherein the one first orifice and the one second orifice effect the lowering of the pressure and/or flow rate
• wherein the distance (X) between the first orifice plate and the second orifice plate is dependent on the first diameter (d1) and/or the second diameter (d2);
• and wherein the first orifice plate and the second orifice plate have a thickness of about 3 mm for the upstream pressure up to 14 kg/cm2 in a tubular structure having an effective diameter (D) of 13 mm.
