Because sal is the finite verb, and in a normal Afrikaans main clause the finite verb goes in the second position.
When there is a helper verb like sal, the main verb usually moves to the end:
This is a very common Afrikaans pattern:
So the end position of ontmoet is normal.
Mekaar means each other or one another.
It shows that the action is reciprocal: the two or more people are meeting one another.
So:
For English speakers, mekaar is an important word because Afrikaans often uses it where English uses each other.

In this sentence, the part after sal is arranged like this:
A very common neutral pattern is:

Afrikaans does allow some flexibility for emphasis, but this version is a very normal default order.
In this sentence, môre means tomorrow.
Afrikaans uses môre in both time-related senses, and context tells you which meaning is intended.
For example:
So here, because the whole sentence is about a future meeting, môre is understood as tomorrow.
By often means at, by, near, or sometimes with, depending on context.
In this sentence, by die stasie means at the station as a meeting location.

So you can also say:
Because môre already shows future time, that sentence can still mean We are meeting each other at the station tomorrow or We meet each other at the station tomorrow.
Adding sal makes the future especially explicit:
