Daniel Senior Dual Chamber Orifice Fitting

With over one million Daniel™ Senior™ Orifice Fittings in service worldwide, this differential pressure flow meter reigns as the most widely used device for unparalleled measurement accuracy in accordance with AGA 3, API 14.3 and OIML 5167. The industry-leading dual-chamber design saves time and money by providing a fast, safe and extremely simple method of changing orifice plates under pressure to prevent unscheduled downtime. A unique plate carrier ensures superior concentricity to reduce measurement uncertainty and also allows the fitting to be mounted in a vertical or horizontal plane. No need for costly bypasses or additional valves that are required with conventional orifice flanges simplifies installation and startup.
