MADE IN USA. The EVKeg is a safe, durable polyethylene beer keg (150 PSI capability) that has the unique features of using an ozone sanitized liner that is replaced with every fill eliminating the need for keg cleaning, and a self setting pressure relief valve that prevents the keg from accidental over pressurization.
Orifices are generally used as measuring and hydraulic control devices. Orifice. hydraulics control the function of many submerged inlet - free outlet culverts, primary spillways in detention facilities, manholes in conduit flow, and in storm drain.
The most common method of measuring gas is through an orifice meter. Gas flows through a piece of straight pipe with an orifice plate inserted in the middle. The orifice plate is a steel circular plate with a hole in the middle; the hole is smaller than the internal diameter of the pipe. The plate is placed perpendicular to the gas flow, and is sealed so that all the gas flows through the hole. The hole is tapered, meaning that the edge of the orifice hole is sharp.
