The Daniel Flow Nozzle is a high‑precision differential pressure flow measurement device engineered for industrial and UK oil & gas applications where reliable, repeatable, and low‑maintenance flow data is required.
Designed for pipeline custody transfer metering, transmission and distribution flow measurement, and process control systems, the Daniel Flow Nozzle provides accurate volumetric flow measurement of clean gas, liquids and multiphase flows in critical environments.
Its robust construction and streamlined flow profile minimise pressure loss while delivering stable flow signals for differential pressure transmitters, making it ideal for custody transfer in oil and gas pipelines, wet gas and multiphase systems, offshore platforms, FPSOs, refineries, petrochemical plants, large industrial facilities and wastewater processing operations.
Manufactured to industry‑recognised standards such as ISO 5167, AGA 3 and API 14.3 bore and geometry tolerances, the flow nozzle supports high turndown ratios, consistent discharge coefficient performance, and long‑term measurement repeatability. Whether used for pipeline custody metering, process optimisation or industrial flow measurement systems, the Daniel Flow Nozzle delivers accurate differential pressure flow results and robust operation in demanding service conditions.
- Achieves measurement accuracy of ±0.8% with repeatability of ±0.1%, and up to 0.25% accuracy with flow lab calibration.
- Available in sizes from 2″ to 24″, with larger sizes available upon request.
- Offered in flanged, tapped, weld-in, and holding ring designs to suit various applications.
- Available in stainless steel, duplex stainless, carbon steel, and other weldable materials based on system requirements.
- Provides 60% greater flow capacity than an orifice plate with the same beta ratio.
- Ideal for high-velocity fluids, delivering better accuracy as flow rates increase.
- Excels in high-pressure, high-temperature environments, making it the preferred solution for demanding applications.
