What is a Coriolis Flow Meter?
By using motion mechanics, Coriolis flowmeters measure the rate at which given masses of corrosive and clean liquids and gases flow through a tube. A Coriolis meter directly measures the mass flow rate with high accuracy while simultaneously measuring density, temperature, volumetric flow rate, and concentration.
Mass flow rate, direct measured by Coriolis force
Coriolis force: F=2mωv
(F: Coriolis force, m: mass, ω: angular velocity, v: velocity)

Mass and Density Flowmeter - ROTAMASS Total Insight Coriolis
A Coriolis mass flowmeter measures mass through inertia. Liquid or dense gas flows through a tube that is vibrated by a small actuator. This acceleration produces a measurable twisting force on the tube proportional to the mass. More sophisticated Coriolis meters employ dual-curved tubes for higher sensitivity and lower pressure drop.

ROTAMASS Total Insight Coriolis Meter Accuracy
Regarding the vibration noise from the pipeline, the “box-in-box” design of the ROTAMASS TI isolates the flow tubes from the process connection. By absorbing the mechanical noise or any external forces from misalignment from the pipeline, it delivers an excellent zero stability and final flat accuracy. The ROTAMASS TI performance made it possible for the customer to make process improvements, which resulted in higher efficiency between the fuel consumed and the power generated. It was a major improvement over the prior metering system.
Further digitalization support by Total Insight includes compatibility with SensPlus™ Buddy, which is a communication support service for providing support to sites from a remote location using a mobile device. Its operation is intuitive and it enables visual transmission by video calls and augmented reality (AR) as well as information sharing by sending images and text. Smooth and accurate communication using SensPlus Buddy improves the efficiency of maintenance work and reduces losses due to mistakes. This tool facilitates safe and worry-free maintenance activities.

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.
Accurate and reliable measurement of wash oil in a high temperature process to avoid solidification of the chemical, it is essential to adjoin heat and insulation to the piping and equipment. Therefore, thermal management of the pipe runs is required, to avoid any heat loss in the fluid to maintain the fluid properties.
The process consists of mixing meats, oils, and water to create a finished product, animal feed, using a PLC-based automation system.
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.
