Yes, that’s about what I meant when I say two-dimensional. Only the split rings should overlap a little to give a reading in any direction. There is a lot more to do with this depending on how sensitive it is allowed to be or must be. An example is that the weight can be lowered in an oil filled container to absorb sudden moves. But then we have to know more about the application.
I believe alchol is used in levels, as oil has a tendency to thicken with low temp and hinder the movement.
