Coriolis flowmeter for precise and accurate flow measurement  

Technology you can trust in hazardous areas, critical applications and highly regulated industries

The process control industries are characterized by the need for accurate, consistent and safe measurement to ensure proper quality, compliance and profitability. Each industry is unique in certain ways, but there are a few universal requirements—one of these being the need to measure flow of various liquids and gases. There is no single “best” flowmeter, but rather numerous technologies available for measurement, each designed to best fit your process and application requirements.   

 Coriolis flowmeters simultaneously measure mass flow, density and temperature of a fluid as it passes through one or more vibrating measuring tubes. Certain models can even provide viscosity measurement as well. As the fluid progresses through the flowmeter, its inertia causes the internal tubes to twist and bend due to the Coriolis effect, with the inlet and outlet oscillating out of sync. The instrument’s sensors detect this phase difference between the inlet and outlet sensors, which corresponds directly to mass flow in the tubes. 

Additionally, the fluid’s density can be determined from the oscillation frequency of the measuring tubes. Dense fluids oscillate slower, and lighter fluids such as gases oscillate at a higher frequency. The tube temperature is registered to compensate for thermal influences and is available as an instrument output signal.

Cost savings  

Coriolis flowmeters are versatile—making them the best choice in many fluid measurement applications—including water, cleaning agents, solvents, other chemicals, fuels, crude oil, vegetable oils, animal fats, latex, silicon oils, alcohol, fruit solutions, toothpaste, food products, vinegar, gases and liquefied gases. 

In addition to mass flow, density and temperature, Coriolis technology can measure characteristic values, including volumetric flow, solids content, concentration, viscosity and more. The measured values and data from Endress+Hauser Coriolis flowmeters are available through multiple different digital and analog communication protocols, allowing easy integration with any control system. 

These flowmeters provide high measurement accuracy—typically with a maximum mass flow measurement error of ±0.1% or less. This is especially useful in highly regulated industries where precision is key, such as in the life sciences sector when producing pharmaceuticals. This is also critical for custody transfer applications, where small measurement errors can add up to large dollars of unaccounted for product. 

Endress+Hauser’s Coriolis portfolio includes over 17 sensor options and 5 electronic transmitter options. Each of which is specialized to perform best in different applications and industries. With so many sensor options to choose from, sometimes it can be daunting to select the right technology for your application. The main sensor options for most applications across all industries are the Promass F, Promass Q, Promass E, Promass K and Promass A.  

Coriolis product highlights across applications:

Promass F 200- Coriolis flowmeter
Promass F 200: For broadest range of applications
Promass Q 500- Coriolis flowmeter
Promass Q 500: For custody transfer applications
Promass K 10- Coriolis flowmeter
Promass K 10: For  basic applications featuring air, gas, fuel and water
Promass A 300
Promass A 300: For continuous process control in very demanding applications
Promass E 100
Promass E 100: For measuring liquids and gases in a wide range of standard applications

Because Coriolis flow measurement’s operating principle is based on mass and fluid inertia and has no moving parts the technology works regardless of the measured fluid’s properties, including viscosity, temperature, and density. This results in less frequent calibration requirements, even when using the same flowmeter to measure a variety of fluids.  Additionally, Coriolis flowmeters can be installed in tighter spaces than most other types of flowmeters, or near pipe turns because they do not require straight runs of inlet or outlet piping.  Combined with reduced calibration and maintenance requirements, the cost of ownership for the equipment’s lifecycle is significantly reduced compared to other flow measuring technologies.

Ideal applications for Coriolis flowmeters 

Coriolis flowmeters are suited for use in all industries, including life sciences, chemicals, petrochemicals, oil and gas, food and beverage, utilities and more. This technology is optimal where high-precision flow measurement is required, especially in conditions that pose challenges for other similar technologies. 

Versatility can come with a higher initial cost, but the lack of maintenance and continued performance in changing fluid conditions makes the total cost of ownership of a Coriolis meter significantly less than other technologies.
