The basic operation of Coriolis flow meters is based on the principles of motion mechanics. As fluid moves through a vibrating tube it is 
forced to accelerate as it moves toward the point of peakamplitude vibration. Conversely, decelerating fluid moves away from the point 
of peak amplitude as it exits the tube. The result is a twisting reaction of the flow tube during flowing conditions as it traverses each 
vibration cycle.

Coriolis flow meters are used in a wide range of critical, challenging applications, in industries including oil and gas, water and wastewater, 
power, chemical, food and beverage, and life sciences.

Coriolis mass flowmeter can measure mass flow directly, and it can also measure temperature and density. What's more, transfer measurement by mass is the most accurate method, since mass is independent of , and unaffected by, changing process fluid characteristics, including pressure, temperature, viscosity, conductivity and gravity. 

To measure the flow rate of plam oil, we recommend our customer to use Coriolis mass flowmeter and up to now, it's working well at the palm oil factory.
The following is the Coriolis mass flowmeter working site for palm oil.
