Here’s why you should consider a Coriolis flowmeter in your industrial processes 

By Lauton Rushford, Flow Product Marketing Manager at Endress+Hauser

In industrial environments, choosing the right flow measurement device can significantly impact product quality, process efficiency and operational safety. Enter the Coriolis flowmeter, which uses the Coriolis effect to deliver accurate, multivariable data in real time.  

The Coriolis effect is a physical phenomenon that occurs when a mass moves within a rotating or oscillating system. As the mass flows through a vibrating tube, it experiences a deflection due to inertia. This twist or phase shift is what Coriolis flowmeters detect and measure. The greater the flow rate, the greater the deflection, allowing the flowmeter to calculate mass flow with high precision.  

Coriolis flowmeters operate by vibrating flow tubes and measuring the phase shift caused by fluid movement. This shift, a result of the Coriolis effect, is directly proportional to the mass flow rate. Sensors also detect changes in resonant frequency to determine fluid density, while integrated temperature probes provide thermal data. These measurements allow for real-time monitoring of fluid properties, even in complex or multiphase flows. 

Coriolis flowmeters offer several key benefits: 

• Direct mass flow measurement without the need for conversion from volumetric flow 

• Multivariable sensing including mass flow, density, temperature and viscosity 

• High accuracy and repeatability, even in challenging conditions 

• No moving parts, reducing maintenance and increasing reliability 

• Application-specific designs; Endress+Hauser offers 17 sensor types tailored to industry needs

Innovations such as Proline Promass Q, which compensates for entrained air using multi-frequency oscillation, and Proline Promass U, a single-use flowmeter for sterile pharmaceutical environments, further expand the technology’s versatility. Proline Promass I adds viscosity monitoring and trending for Newtonian and non-Newtonian fluids, while the Proline Promass K 10 introduces IO-Link connectivity for cost-effective digital integration. 

Proper installation is critical to ensure optimal performance. Consider the following: 

• Horizontal or vertical placement affects how fluids behave inside the flowmeter 

• External vibrations can interfere with internal oscillation; use dampeners or brackets 

• Ensure the flowmeter’s materials match operating conditions

• Confirm compatibility with control systems (EtherNet/IP, IO-Link, etc.)

• Use factory-calibrated sensors and enable Heartbeat Technology for real-time verification

Unlike other flowmeters, Coriolis devices typically do not require any straight pipe run, but ensuring the tubes are fully filled during operation is essential.
