Orifice primary flow elements, flange unions, and holding blocks offer lower capital investment and ease of replacement. The technologies are field-proven and well suited for a variety of applications.
The orifice plate is one of the most common differential producer type flow elements for measuring clean liquids, gases, and low-velocity vapor (steam) flow. The design offers optimum flexibility ideal for applications with many diverse existing piping schemes, and require considerably lower investment for the initial purchase of equipment. The orifice plate also has the advantage of relatively easy and low-cost replacement.
