Application
The
Delta Controls Model P72 is needed when a large
tank has nonlinear tank walls such as does a horizontal cylinder or a sphere.
It also is used where indoor tanks only have limited headspace above them. Most
applications require the optional bottom weight to keep the cable taut.
The Delta Controls Model P72 probe is a Model P71 to which a parallel ground
reference cable has been added. Many nonconductive liquids have low
dielectric
constant values. It is important that the rangeability tables be consulted
and followed to insure adequate intrinsic gain of the probe. A parallel
ground cable
will usually solve rangeability problems in large tanks of low dielectric
liquids. The P72 should generally be used when the level change is
less than ten (10)
feet, where the tank diameter is greater than eight (8) feet, or when the
measured liquid has a low dielectric constant (less than 3.5 units).
Low dielectric liquids
include fuel oil, gasoline, benzene, and liquefied petroleum gasses. The
Delta Controls Model P72, with parallel ground cable, is required when
the tank has
a nonlinear ground reference wall, such as is found in a horizontal cylindrical
tank or an LPG sphere. This probe is not suitable for service in powders
or
solids.
