Compare magnetic flow meters and turbine flow meters in terms of principle of operation and typical applications.

• A. Turbine meters rely on magnetic induction principles.
• B. Magnetic meters measure flow of conductive liquids via Faraday's law; turbine meters use a rotating turbine whose speed is proportional to flow.
• C. Magnetic meters measure flow of conductive liquids; turbine meters measure viscosity.
• D. Both measure density and require temperature compensation.
