Orifice plates

The orifice plate is an instrument used for measuring flow rate constructed as a thin metal plate with a hole in the middle. Our types include the classic plates to be installed between orifice flanges or orifice plates with built-in tappings that can be mounted between regular flange connections. For pipe sizes below 2 inches, we offer our meter run. The simplicity of the design makes for a cost-effective solution.
