SS Flow Nozzle

Product Description

SS Flow Nozzle is useful to measure the flow rates of the liquid discharged into the atmosphere. This nozzle is easy to install and remove when need. It is known for its wear resistant and chemical resistant in nature. It is applicable for chemical substances and high temperatures.

Product Specifications & Standards

• Pressure Tappings: Standard NPT/BSPT; also BSP, socket weld, nipolet, nipoflange, etc.

Technical Details & Performance

Measurement Principle: Utilizes differential pressure at nozzle throat to calculate flow rate (pp), similar to Venturi/orifice theory

Uncalibrated Accuracy:

• ISA1932: 0.8% to 1.2%
• LongRadius: ~2%
• Venturi Nozzle: 1.2%1.7%
• Calibrated Accuracy: Reduced to 0.25% with accredited flow calibration (e.g., PTC6 test sections)
• Flow Capacity: Handles ~55% higher flow than orifice plates with similar ratio
• Permanent Pressure Loss: Typically 5%70% of P; Venturi designs trend lower
• Reynolds Number Range: 1010 (short ISA/nozzle), up to 210 for some variants
• Upstream/Downstream Requirements: Requires less straight run than orifice/Venturi meters

Construction & Types

• ISA 1932 Nozzle converging profile, cylindrical throat, sharp outlet
• LongRadius Nozzle quarter-circle entry, cylindrical throat
• Venturi Nozzle adds a diffuser cone for better pressure recovery
• ASME Throat Tap / PTC6 includes upstream/downstream piping & flow straighteners for high-precision measurement

Configurations

• Weldin, flangeinpipe, or flange-mounted within bolt circle
• Available as integrated meter runs with flow conditioners & tappings

Key Advantages

• Durability & Erosion Resistance: No sharp edgesreduce wear/erosion vs. orifice plates
• Higher Throughput Efficiency: Up to 55% higher flow capacity
• Compact & Low Piping Needs: Good for space-constrained installations
• Wide Temperature & Pressure Capability Ideal for steam and high-velocity applications
• High Accuracy with Calibration 0.25% uncertainty achievable

Typical Applications

• Steam flow in power plants, boilers, turbines
