Coriolis flow meters
Deliver unmatched reliability for your mass flow, volume flow & density measurement needs.
​
Emerson’s Micro Motion Coriolis meters offer precise mass flow and density measurement through a combination of a sensor (with measurement tubes) and a transmitter (for displaying and configuring outputs). The product line includes various sensors, transmitters, and software options designed to meet diverse application needs, providing a comprehensive and reliable solution for critical flow measurement processes
​
A Coriolis meter measures mass flow using motion mechanics. The fluid entering the sensor is divided into two vibrating tubes. A drive coil makes the tubes oscillate in opposite directions at their natural frequency. As the tubes vibrate, sensors produce sine wave signals, and the time delay between the two waves, known as Delta-T, is directly proportional to the mass flow rate.
​
Range - Coriolis flow meters are widely used across many industries for accurate flow measurement. They come in various sizes and can measure flow rates from a few grams per hour up to about 54,431 kgs/min. Their linear signal provides a wide and dynamic measurement range.

​
Measurement Principles
-
The Coriolis mass flow meter works by vibrating the flow tube that carries the fluid. This vibration creates a rotating reference frame that produces the Coriolis effect. Sensors detect changes in the tube’s frequency, phase shift, and amplitude, and these variations are used to determine the fluid’s mass flow rate and density.
​
Mass and volume flow measurement
-
​The measuring tubes are forced to oscillate producing a sine wave. At zero flow, the two tubes vibrate in phase with each other. When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift. The time
difference between the waves is measured and is directly proportional to the mass flow rate. Volume flow rate is calculated from mass flow rate and the density measurement.
​
Temperature measurement
-
Temperature is a measured variable that is available as an output. The temperature is also used internally in the sensor
to compensate for temperature influences on Young’s Modulus of Elasticity.​
