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 majority of producing wells measure natural gas production with an orifice style meter. Orifice meters have no moving parts and are easily serviced in the field. Differential pressure is measured and recorded as gas passes across an orifice plate, creating a pressure drop allowing for a calculation of the volume of gas passing through the pipe.
