Application Suitability Determines Accuracy
When pipeline wall thickness, linings, or scaling cause severe signal attenuation in clamp-on types, the insert-type directly contacts the fluid, avoiding wall interference and achieving higher accuracy (e.g., thick-walled chemical pipelines, scaled sewage pipelines).
In ideal pipeline conditions (thin walls, smooth surface, uniform material), clamp-on types avoid flow field disturbance from probes by non-contact measurement, ensuring more stable results (e.g., clean water transmission pipelines).
Impact of Installation and Maintenance
Insertion type:
Requires hot tapping. Incorrect probe positioning (e.g., near elbows or valves) may cause errors due to turbulent flow.
Clamp-On Type:
Easy to install, but unstable coupling or poor pipe surface treatment can lead to signal fluctuations.
Limitations of Fluid Characteristics
Insertion type:
Unsuitable for highly corrosive or high-viscosity fluids (probe corrosion/clogging risk). Clamp-on type is more reliable in such cases.
Clamp-On Type:
Unsuitable for fluids with high bubble/solid content (severe acoustic scattering). Insert-type is preferred here.
Selection Recommendations
Prioritize Insertion-Type:
For thick-walled pipes, complex linings/scaling, non-metal pipes, and stable fluids (non-corrosive, low-viscosity).
Prioritize Clamp-On Type:
For thin-walled pipes, clean fluids, and non-intrusive scenarios (e.g., temporary monitoring, drinking water pipelines).
Extremely High Precision Requirements:
Integrate pipeline conditions and fluid properties for comprehensive evaluation, or compare actual errors through on-site testing.
Accuracy depends on application suitability rather than the type itself. Key considerations include pipeline conditions, fluid characteristics, and installation feasibility.
