    First, you break the circuit into two parts.

    The right op-amp is just a buffer. It seems to simply isolate the left op-amp circuit from the rest of the system. The rest of the system is not shown.

    The left op-amp is an none-inverting configuration. So the Gain=1+(Rf/Rin). If I am not mistaken it looks like Gain=1+(10k/10k)=1+1=2.
