PX4Flow usage at 100 meters

Hi there, I want to try PX4Flow at 100 meters. Is it possible if I add 100-meter range finder like SF11/C and make work at 100 meters?

Also, can I edit the IMAGE_WIDTH, IMAGE_HEIGHT parameters? The documentation says only read but is there any possible way?

Also if I increase the IMAGE_WIDTH, IMAGE_HEIGHT parameter from 64x64 pixel to 752x480 pixel, will it work at the same accuracy? I know the 400Hz processing speed will decrease. But how about flow accuracy?

One thing to note is that you need to adjust the focus of the lense for that distance (or just infinity at that point).
