The QED ORP215M-R Wellhead combines easy plate exchanges for more accurate flow measurement with precise adjustment of gas flow, especially at very low rates (under 10 scfm). Changing to the correct orifice plate takes only seconds, with no time wasted shutting down the control valve or retuning the well. Exclusive to the ORP215M-R family, a complete kit of six orifice plates is securely attached to the wellhead for quick access. A removable dust cover permits easy confirmation of plate size, giving you the highest confidence in your flow measurements. The Precision Fine Tune Control Valve provides rigorous control of gas flow. Unlike traditional valves, this unique design achieves near linear flow adjustment across its entire range. Molded, glass-filled polypropylene boosts strength and resistance to harsh field conditions, significantly increasing wellhead durability. Easier hose fitting and simpler service save valuable field time and help reduce maintenance and labor costs.
