6.4.7. K factors (in pulse/l) of the fusion spigots and welding sockets with radius for
measuring devices with a g2'' nut
When the dimensions of the pipe are slightly different from dimensions d and s given in the table, recalculate the K factor using one of
the formulae in chap. 6.4.2.
If the measuring device does not automatically convert the K factor, use the following conversion formulae before setting the para-
meters of the device:
• K factor in pulse/US gallon = K factor in pulse/litre x 3.785
• K factor in pulse/UK gallon = K factor in pulse/litre x 4.546
