The flanged mounting arrangements show possible configurations of our Reflex and Thru-Vision Gauges. When specifying, please indicate your prefered configuration by calling out the style number of the assembly, size, type, pressure rating of the flanges required, and the "A", "C" and "D" dimensions. If you do not specify the visibility "B" dimension desired, we will provide maximum visibility according to the dimension given. Connections between the gauge and flanges can be furnished with or without welding.
