V-Cone Flowmeter
A self-rectifying 3-D flow solution engineered to deliver ±0.5% precision in extreme temperatures up to 850°C and space-constrained pipelines requiring zero straight-pipe runs
Specifically designed for unclean fluids and gas-liquid two-phase media, the V-cone flowmeter features a "no stagnation zone" architecture. The aerodynamic shape of the cone forces media to flow around the edges, preventing the accumulation of dirt, moisture, or debris. This results in a wear-resistant, maintenance-free solution for coke oven gas and industrial wastewater.

When to Choose Differential Pressure Over Other Technologies
Comparison with Electromagnetic & Ultrasonic Flowmeters
V-Cone Advantages:
- No electrical power required (DP transmitter only needs 12-24V DC)
- Works with any fluid (conductive or non-conductive, clean or dirty)
- Proven technology (DP measurement understood globally)
- High-temperature capability (to +400°C with appropriate materials)
- Extreme pressure capability (to 420 bar)
- Lower cost than electromagnetic for large pipes (>DN300)
- No moving parts, no wetted electronics
When to Choose Electromagnetic:
- Higher accuracy required (±0.2-0.5% vs. ±0.5-1%)
- Zero pressure drop critical
- Bidirectional flow measurement
- Very low flow velocities (<0.3 m/s)
- Fluid is conductive liquid only
When to Choose Ultrasonic:
- Non-invasive installation preferred (clamp-on)
- Cannot tolerate any pressure drop
- Custody transfer accuracy critical
V-Cone Sweet Spot:
- Gas, steam, or liquid measurement
- pace-constrained installations
- Dirty fluids or slurries
- Wide temperature/pressure range
- Moderate pressure drop acceptable
V-Cone Flow Measurement Across Critical Applications
Proven performance in space-constrained and challenging fluid conditions
Unclean Gas & Coke Oven Gas Monitoring
The definitive solution for "dirty" gas measurement in steel and petrochemical plants. Its self-cleaning design prevents the accumulation of tars and moisture, ensuring consistent flow data in environments that clog traditional meters.
High-Pressure Steam & Power Generation
Optimized for superheated and saturated steam at temperatures reaching 850°C. Its rugged construction and stable signal output provide the mass-flow data required for high-efficiency boiler control and energy audits.
Offshore Oil & Space-Constrained Retrofits
The primary choice for offshore platforms and crowded mechanical rooms. Its 0-3D straight-pipe requirement allows precision measurement points to be added to existing manifolds without expensive structural changes.
Compressed Air & Nitrogen Distribution
Provides high-sensitivity tracking for industrial gas systems. The V-cone’s high-frequency signal resolution captures subtle flow fluctuations, identifying system leaks and optimizing air compressor bank efficiency.
Gas-Liquid Two-Phase (Moisture) Measurement
Uniquely capable of handling fluids with a liquid mass percentage up to 5%. This ensures accurate data for wet natural gas and biogas applications where standard differential pressure meters lose stability.
