Overcoming Unstable Liquid Levels: How Velocity-Area Non-Full Pipe Magmeters Revolutionize Gravity-Flow Telemetry
In municipal wastewater networks, stormwater collection systems, and industrial discharge conduits, fluid rarely flows under continuous pressure. Instead, gravity drives the liquid through partially filled pipes where fluid depth, velocity, and wetted cross-sectional area fluctuate dynamically. ccurately measure partially filled pipe flows with the RBEF-P Series For instrumentation engineers, measuring non-full pipe flow has historically meant making risky compromises: Flumes & Weirs: Require heavy civil modification, create head loss, and catch debris/sediment. Level-Only Ultrasonic Transducers : Estimate flow based on theoretical pipe geometry curves, which completely fails during backwater conditions or variable line roughness. Standard Full-Pipe Magmeters : Suffer from signal breakdown, severe jump errors, or total diagnostic alarms whenever the fluid level drops below the top electrode. To bridge this operational gap, R&B Instrument Inc . developed the RBEF-P Non-Ful...
