Types of Flow Meters & How to Choose the Right One
Types of Flow Meters
Coriolis
Coriolis meters are generally considered the most repeatably accurate flow meters available today. Coriolis meters are ideal for any application where high accuracy is a key factor for consistent product quality, safety and revenue. They are often applied in custody transfer applications due to their excellent accuracy over broad conditions and low maintenance requirements.
Mass Flow Meter Principles
Mass flow meters measure fluid mass flow rate by factoring in density and velocity, unlike traditional volumetric meters. Ideal for accuracy-dependent applications, they are commonly used in industries like chemical processing, oil and gas, and pharmaceuticals. Coriolis meters use the Coriolis effect to detect vibration changes correlating to mass flow, while thermal dispersion meters measure heat dissipation from a probe in the flow stream.

Frequently Asked Questions
Explore common questions and answers to help you choose the right Emerson flow meter technology for your application.
Coriolis flow meters measure mass flow directly by detecting the force exerted by the fluid moving through vibrating tubes. This technology provides high accuracy and is suitable for a wide range of fluids, including those with varying densities and viscosities. They are often used in custody transfer applications due to their excellent accuracy over broad conditions and low maintenance requirements.
Magnetic flow meters are ideal for measuring the flow of conductive liquids, such as water, acids, and slurries. They are commonly used in industries like water and wastewater treatment, metals and mining, chemical processing, and food and beverage. Magnetic flow meters offer improved reliability, unparalleled process insight, and an intuitive operator interface that delivers industry-leading performance.
Vortex flow meters are suitable for measuring the flow of clean liquids, gases, and steam. They are often used in applications where low maintenance and high reliability are essential, such as in HVAC systems and steam flow monitoring. Vortex flow meters simplify installation, maintenance, and verification using a gasket-free meter design to ensure maximum process reliability.
Non-intrusive ultrasonic flow meters provide accurate measurement without direct contact with the process, making them suitable for applications where direct contact is not possible or desirable
Selecting the appropriate flow meter depends on factors like fluid type, flow rate, temperature, pressure, and required accuracy. Emerson provides tools and expert guidance to help determine the best technology for your specific needs.
