Economical Magnetic Measurement for Large Pipes Insertion Electromagnetic Flow Meter is designed for large municipal, irrigation and industrial water lines where a full-bore meter is costly or difficult to install. Large flanges, heavy lifting and shutdown time can dominate project cost, yet a single insertion point must represent the whole pipe profile. An insertion electromagnetic sensor measures conductive-liquid velocity through a comparatively small process connection and can reduce civil and mechanical work. Measure Local Velocity With Minimal Pipe Work Based on Faraday induction, the magnetic flow meter measures the voltage created as a conductive liquid moves through a magnetic field. With no rotor or obstruction in the bore, it introduces virtually no additional pressure loss and avoids the wear mechanisms found in mechanical meters. Gallop lists accuracy up to ±0.5 percent for the core electromagnetic series, conductivity from 5 µS/cm, integral and remote structures, and a wide selection of liners and electrodes. PTFE, PFA, rubber or polyurethane linings can be paired with 316L, Hastelloy, titanium or tantalum electrodes according to chemical and abrasion needs. Hot-tap or retractable arrangements may be considered when supported by the selected model and site procedure, with final pressure rating and safety controls confirmed before purchase. This page can naturally support buyer terms such as magnetic flow meter, conductive liquid measurement, no pressure loss, 4-20 mA flow transmitter and industrial flow totalizer. Make the Velocity Profile Part of Commissioning Provide the true inside diameter, wall thickness, liner, insertion fitting, flow range and straight-run geometry; set insertion depth precisely and perform an in-situ profile or reference check when accuracy is critical. Use the programmed pipe area, K factor and output scaling consistently across the transmitter and control system, and retain commissioning records for future verification. Magnetic meters require a sufficiently conductive, completely filled pipe and proper grounding. Entrained air, empty-pipe conditions, coating electrodes and an incorrect liner or electrode choice can undermine an otherwise strong measurement. Gallop states a one-year warranty, long-life maintenance and installation guidance. Include commissioning support, spare-part recommendations and response expectations in the commercial review so service terms are as clear as the instrument specification.
