Daniel Orifice Plates and Plate Seals

Daniel

Exceptional performance and superior durability are the hallmarks of Daniel™ Orifice Plates and Plate Seals. Available in a variety of line sizes and materials, these simple yet effective differential pressure measurement solutions are compatible with all Daniel fittings (Senior, Junior, Simplex and Orifice Flange Unions) and continue to be one of the most widely used oil and gas flow measurement technologies. Every Daniel plate is expertly manufactured to meet or exceed AGA 3/API 14.3 standards and a variety of plate materials and seal options, including nitrile (NBR) and PTFE, are available to ensure optimum performance in extreme conditions as well as to eliminate the possibility of gas leakage or spillage of liquids.

Features

  • Even the finest meters with the best available flow conditioning equipment and best design configuration can’t escape the inevitable: internal meter tube build-up, meter component damage, and installation problems that contribute to measurement uncertainty. Even a slight coating build-up from product residue on the inside of a meter or meter tube can affect measurement uncertainty by over 1%. Such uncertainty can be more costly than ever in terms of lost and unaccounted for product.

    The Daniel Meter Inspection and Recertification Service is the ideal remedy for internal meter tube build-up, component damage and installation problems. With this service, a certified Daniel Field Engineer will inspect your metering system using the latest in borescope technology and take the necessary steps to ensure the meter tubes and devices are cleaned and recertified to meet the requirements of AGA3/API 14.3 or any other measurement standard.

    • Mitigate measurement uncertainty
    • Minimize the financial burden of lost and unaccounted for product
    • Ensure and verify measurement accuracy to design standards
    • Identify and eliminate installation problems
    • Provide full documentation of all activities and findings
    • On-site service minimizes downtime and transportation costs
  • Improve performance and durability by selecting from a number of optional integral plate seals
  • Eliminate leakage or spillage and mitigate extreme atmospheric and/or process conditions with NBR or PTFE seals
  • Enhance measurement of clean, dry gas or low viscosity fluids with a 45° bevel on the bore hole periphery
  • Select counter, segmental or quarter-round bores to improve performance on dirty gas or other challenging fluids
  • Rely on rigid quality control that ensures plate bore size and bevel complies with AGA 3, API 14.3 and/or ISO 5167
  • Simplify troubleshooting and minimize long-term maintenance with one of the easiest to use measurement devices
