Precision Quick-Change™ Orifice Plate Wellhead

Precision Quick-Change Orifice Plate Wellhead

QED’s new 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.

With the Quick-Change™ Orifice Plate (Patent Pending) feature changing to the correct size plate can be done in seconds. Using the most appropriate size plate and achieving a pressure drop of 0.5-6 inches 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.

Quick-Change Orifice Plate Advantages:

  • Easy-to-change plates are visible through accessible plate housing
