How do different types of flow transmitters work?

Question

Accepted Answer

Flow transmitters measure fluid flow rates using various principles like differential pressure, electromagnetic, and ultrasonic methods.

Differential Pressure Flow Transmitters: Measure pressure drop across an orifice plate; commonly used in oil and gas industries.
Electromagnetic Flow Meters: Utilize Faraday's law of electromagnetic induction; ideal for conductive fluids like water.
Ultrasonic Flow Meters: Use sound waves to measure flow velocity; suitable for clean liquids and gases.
Turbine Flow Meters: Measure flow based on the rotation of a turbine; often used in fuel and chemical applications.
Coriolis Flow Meters: Measure mass flow and density; highly accurate, used in food and pharmaceutical industries.
