Features & Key Advantages
Self-Conditioning Flow Profile
The centrally positioned V-shape cone reshapes velocity profiles, eliminating turbulence with minimal straight pipe runs (0–3D upstream, 0–1D downstream).
Extremely Low Pressure Drop
Produces significantly lower permanent pressure loss compared to standard orifice plates, nozzles, and venturi tubes.
Stain-Resistant & Clog-Free
Designed to handle harsh media, dirty liquids, slurries, and suspended contaminants without clogging or signal noise degradation.
High Accuracy & Repeatability
Delivers high accuracy up to ±0.5% for liquids and ±1.0% for gas/steam with a remarkable 0.1% repeatability.
Extreme Environment Handling
Capable of operating reliably under broad temperature conditions from cryogenic -196°C up to extreme heat at 850°C.
Versatile Multivariable Integration
Seamlessly interfaces with multivariable transmitters or third-party DP transmitters across flexible mounting configurations.
