ABB Measurement & Analytics Orifice carrier assembly with integral manifold FPD175

The FPD175 is a compact orifice carrier assembly designed for simplified installation and commissioning in flow measurement applications. It features a wafer-bodied design with an integral orifice plate and corner tapping points, along with an integral welded 3-valve or 5-valve manifold. This assembly allows for direct mounting of differential pressure or multivariable transmitters, reducing the need for separate manifolds and impulse piping, which can lead to lower installation costs. The FPD175 supports both fixed and removable orifice plates, providing flexibility for maintenance and reconfiguration based on changing process conditions. It is available in single-hole and multi-hole formats, with options for a balanced orifice conditioning plate that enhances accuracy and reduces pressure losses compared to standard designs. The assembly can accommodate various pipeline orientations and is compatible with flanges up to ASME 600 or DIN PN100. Engineers may find the FPD175 beneficial for its ease of installation, reduced straight pipe requirements, and options for integral temperature measurement, making it suitable for a range of applications involving liquids, gases, and steam.
