00:00So, in this example, we have a dual straight Coriolis meter, ok?

00:11Just to explain a bit more clear, the fluid that we are going to measure,

00:16whether it's water, orange juice, oil, whatever it is,

00:19it will go through these measuring tubes, ok?

00:24So, we have a driver in the middle, which is here.

00:30And this driver will create a vibration between the two tubes.

00:34And I'm going to show you a few examples of how it works.

00:38So we are creating a vibration between these two tubes.

00:41When the flow starts, this flow will create a force in the measuring tubes, ok?

00:51And if we take Newton's third law, to each action there is an equal and opposite reaction, right?

01:01So, to explain it so we can see it even more clear.

01:07In the Coriolis meter, as I said, we've got the driver in the middle that creates the vibration.

01:14We've got one sensor before and one sensor after, ok?

01:18The distance between the driver and the sensor

01:21are the same as the distance between this driver and the sensor B.

01:25So, imagine we are recording this vibration in the sensors.

01:37And then, like, the same way you are recording an earthquake,

01:41you are checking this vibration.

01:43So, this sensor A, up and down,

01:45it will leave a sinusoidal curve, up and down.

01:48A sensor B will also be leaving a sinusoidal curve, up and down, as you see there.

01:55In this case, because there is no flow,

01:58nothing is creating a force in the measuring tubes,

02:01and the two sinusoidal curves are overlapping.
