Quick-Change Orifice Plates

QED’s new Precision Quick-Change™ Orifice Plate Wellhead (U.S. Patent Number 8,800,597 & Patents Pending) combines easy plate exchanges for accurate flow measurements with precise adjustment control over a broad flow range.

The Quick-Change Orifice Plate feature makes it as easy as 1-2-3 for the operator to change to the most appropriate size plate for the given conditions. Achieving a pressure drop of 0.5" - 5.0" of water column is essential to generate stable flow readings with the best resolution. The accessible plate housing allows for easy confirmation of plate size and placement giving you the highest confidence in your flow reading.

The wellhead control valve design allows you to finely control gas flow even at rates under 10 scfm. The unique design will change the way operators adjust gas flow. Wells can now be tuned by flow rather than by vacuum.

Quick-Change Orifice Plates

QED’s Quick-Change Orifice Plates are available in stainless steel and plastic. With several sizes of orifice plate available, it is easy to select the right plate for the appropriate pressure drop allowing for accurate flow measurement readings.
