flow meters

 Measuring gravity-flow drainage in municipal or industrial pipelines presents a unique engineering challenge: the pipe is almost never completely full. RBEF-P Non-Full Pipe Electromagnetic Flowmete The Instrumentation Dilemma : Traditional solutions force engineers to compromise Full-Bore Magmeters : Require a full pipe; air pockets cause severe signal drift or total signal loss. Parshall Flumes & Weirs: Demand expensive civil engineering, take up huge footprints, and accumulate debris. Submersible Area-Velocity Sensors : Sit directly in the fluid, leading to constant fouling, ragging, and maintenance headaches. How RBEF-P Solves Non-Full Pipe Physics The RBEF-P Series Electromagnetic Flowmeter eliminates the need for U-tubes or weir boxes by dynamically capturing two variables: Total Flow Rate Q=Cross-Sectional Area A×Fluid Velocity V Liquid Level (A): An integrated top ultrasonic or pressure sensor continuously measures the fluid depth to calculate the exact overcurrent (...

In municipal sewage networks , rainwater drainage, and industrial gravity discharge lines, fluid flows naturally without external pressure. As a result, pipes are rarely 100% full.  RBEF-P Series Partially Filled Pipe Magnetic Flow Meter For plant engineers and environmental managers, measuring volumetric flow under these conditions has historically been a major challenge: Standard Magnetic Flow Meters require a completely full pipe (100% liquid volume) to maintain a stable magnetic field and signal. When air is present, standard magmeters generate extreme errors or fail entirely. Open Channel Weirs and Flumes (like Parshall flumes ) require extensive site construction, take up large footprints, and tend to trap solids, sludges, and debris—demanding frequent cleaning. The RBEF-P Series Partially Filled Pipe Magnetic Flow Meter from R&B Instrument Inc . overcomes these limitations by measuring flow velocity and liquid level simultaneously inside an enclosed pipe section. 1.
