Measuring mothed before order:

h1 : it’s the height from the top surface of the manhole cover to the bottom of the tank
h2 : it’s the height of vertical-pipe from the top surface of the vertical-pipe flange to the top surface of the manhole cove. Here is the size of vertical-pipe we recommended: 400mm above the manhole cover, 50mm under the cover.
D (diameter of the tank): it’s the valid max inside diameter of the tank.
L (length of the tank): it’s the valid max inside length of the tank.

Notes: If install the probe from the gauge hatch, you need to add a vertical-pipe at the top of the gauge hatch, and it’s total height of the vertical-pipe and the gauge hatch is more than 400mm.
