Riser Pipe Length Calculations
Minimum Riser Length
Start with the overall length of the probe, add 5 inches (127mm) for the support
chain, and subtract the tank diameter. See Example minimum riser length
calculations (below) for a TSP-LL2-101 probe in two different sized tanks.

Tank diameter – 92(2337) – 96(2438)
Minimum Riser Length = 24(609) 20(508)
It is possible through the minimum riser length equation for the calculation to be
less than 18 inches. It is recommended that the riser be at least 18 inches (457
mm) for a model TSP-LL2 Probe (Reference Figure 2-1).
