Page 14: Design
3.3 Theory of operation Design The SITRANS FMS500 is an electromagnetic flow sensor designed to meet the requirements in ground water, drinking water, waste water, sewage or sludge applications. With its coned design, increased low-flow accuracy is achieved making it especially useful for leak detection. It is suitable for direct burial and constant flooding. - Page 15 The input impedance is extremely high: >10 Ω which allows flow measurements on fluids with conductivities as low as 5 µS/cm. Measuring errors due to cable capacitance are eliminated due to active cable screening. SITRANS FMS500 Operating Instructions, 01/2024, A5E52677520-AA...
