DANIEL FLOW NOZZLE
The Daniel Flow Nozzle combines the simplicity of an orifice plate with the hydrodynamic benefits of a Venturi tube. This versatile flow meter is ideal for high-pressure, high-temperature systems where high-velocity fluids need to be measured. Commonly used in power plants, refineries, and processing facilities, the Daniel® Flow Nozzle excels in handling challenging fluids such as steam, gas, and liquids. With its gradual, sloping profile, the Flow Nozzle provides increased flow capacity and improved accuracy compared to standard orifice plates, while maintaining a compact design that allows for easy installation between flanges. Standard Accuracy 0.8% standard, 0.25% available with calibration Flow Ranges (turndown) 10:1 or greater Repeatability ± 0.1% or better Permanent Pressure Loss Varies with DP and Beta (H/D) Ratio Beta Ratio 0.4, 0.5, 0.6, 0.7; Additional betas available by request. Line Sizes 2″ to 24″ – 26″and larger – available in any flange specification. Pressure Ratings ANSI 150 thru 2500 Construction Materials All Grades of Stainless Steel, Carbon Steel and Alloys or any other weldable material. End Configuration Wafer, Flanged, Beveled, Threaded and Others Approvals CE-PED 2014/68/EU, CRN
- 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.
