What kind of bit did you use to drill thru the tube side wall?

Kari - i traced out the OD of the 3/4" pipe then drilled and dremel grind until the pipe can fit through snugly. I then grinded down the union and coupling fittings to contour of the OD and ID curve of the tubing.

I'll recalibrate every time I change the media and I'll just unscrew the gland nut with the probe as a whole and then screw it back in. I used gas teflon tape on the threads so its easy to remove.
