Tensile load
Motion of the medium inside of the tank will impart load onto the probe of the transmitter.
Flexible wire probes will experience tensile loading that will be transferred to the roof of the tank.
Ensure that the maximum probe tensile load does not exceed maximum tank roof load. Depending
on position, forces on anchored flexible probes can be two to ten times greater than that of flexible
probes with end weights.

Bending torque
A vertically mounted rigid probe bends due to fluid motion force. An angle mounted
probe also bends from gravity. The mounting angle and total torque from these forces
must not exceed the limits in
conditions consider using a flexible wire probe instead.

*For an angle mounted probe reduce these limits by 50% to allow for bending from gravity.
