The Daniel Senior Dual-Chamber Orifice Fittings are industry-leading dual-chamber differential pressure flow meter primary elements engineered for accurate, repeatable volumetric flow measurement in critical UK oil & gas, pipeline, custody transfer and industrial metering applications.
With over one million units in service worldwide, these orifice fittings provide high-accuracy differential pressure measurement in accordance with AGA 3, API 14.3 and OIML 5167 standards, helping operators achieve dependable flow data without the need for costly flow calibration.
The innovative dual-chamber design permits safe, fast and simple orifice plate changes under pressure without interrupting flow or shutting down the line, reducing unplanned downtime and maintenance costs. A unique plate carrier ensures superior concentricity to reduce measurement uncertainty and supports vertical or horizontal installation, eliminating the need for complex bypass piping or additional isolation valves required by conventional orifice flanges.
Available in a wide range of line sizes (2 in to 24 in) and ANSI pressure ratings with material options including carbon steel, stainless steel and duplex for sour service, these Senior fittings are ideal for custody transfer metering in oil and gas pipelines, allocations measurement, refinery distribution systems and industrial process flow measurement where performance, reliability and easy maintenance are essential.
