Daniel Simplex Single-Chamber Orifice Fitting
Engineered for use on smaller line sizes, Daniel™ Simplex™ Single-Chamber Orifice Fittings offer superior gas and liquids differential pressure measurement performance in accordance with AGA 3, API 14.3 and OIML 5167. Unit-built construction with the plate carrier permanently attached to the sealing bar allows the sealing bar, carrier and plate to be removed as a unit, enabling operators to quickly perform plate inspections and change-outs with no need to remove the fitting from the line. There is also no need to spread the flanges to change the plate, further minimizing downtime and costs as well as eliminating the possibility of costly gas leakage or spillage of liquids.
