Coriolis Mass Flow Measuring Principle

Coriolis versus Thermal Mass Flow for Gases and Liquids



In this application, the customer’s facility was using petroleum-fired generation and required a reliable and accurate flow measurement technology to measure the fuel flow required to run the turbines. The fuel flow to the turbine was to be measured and compared to the power generated by the turbine in megawatts, which would be the direct indication of the power generation efficiency, known as the plant settlement system application.


A milk tanker is typically fitted with a pump and flowmeter that records the volume of milk loaded from each individual farm. Confirmation of the total volume of milk delivered to the dairy plant is performed either by weighing the tanker or via flowmeters in the tanker bays.

Application Note

The process consists of mixing meats, oils, and water to create a finished product, animal feed, using a PLC-based automation system.

Application Note

If the customer could accurately measure the essential oil concentration, then the heat/steam could be adjusted to the correct levels. Increasing the efficiency of the process and saving money.

In the food and beverage industry, government regulations for whisky production require compliance of distillation strengths to strict limits. Yokogawa’s ROTAMASS TI Coriolis mass flowmeter is well-matched for the application with its density calibration for ethanol or water percentage and a special calibration for maximum accuracy and stability. The mass flow meter’s dual bent tube technology and advanced software enabled the customer to measure the very small and sensitive range required. Yokogawa commissioned the mass flowmeter onsite to ensure the correct installation and commissioning from the outset, affording Total Insight through the entire product lifecycle. 


Smart devices, like Yokogawa’s line of Total Insight transmitters and flowmeters contribute to Digital Transformation during operations and throughout the lifecycle of the instrument.
