8.2.4 Dual Channel Level
This template adds Level functionality to the Dual Channel PV
template.
For each channel, this consists of applying a Specific Gravity
calculation to the PV to provide the level of a liquid within a
vessel.
A volume calculation can also be applied to the level to
provide the volume contained within a vessel.
