Remaining Vessel Capacity
To perform a volume conversion for the preceding example, complete the following
programming.
Volume Parameter Settings
Number Description Instructions
P050 Tank Shape
Enter "7"* for horizontal cylinder with
parabolic ends
.
P051 Max Volume
Enter "117" for 117 cubic feet (Use vessel
fabricators value).
P052 Tank Dimension A
Enter "1.5" for
1.5 ft
(the horizontal length of
one parabolic end).
P053 Tank Dimension L
Enter "12" for 12 ft (the horizontal length,
excluding parabolic ends).
* This is the only tank shape where the Span (P007) value must exactly equal the
vessel height.
Now in the RUN mode, the Reading Value and mA output will represent remaining
vessel capacity in cubic feet. If the mA output is still to be scaled to "space" (distance
from material to Full in feet) set the mA Function (P201) to "2".
Application Assistance
The preceding examples describe only two ways in which the SPL can be applied to
process measurement requirements.
The SPL can be used to monitor almost any process (within the temperature,
measurement range, and chemical immunity capabilities of the system) where a
distance measurement or determination of presence vs. lack of presence of an object
is desired.
By thoroughly reviewing the Parameters sections, you may identify some interesting
ways of using the SPL to monitor specific processes.
Milltronics has many years experience applying ultrasonic level measurement to a
variety of processes in the mining, aggregate, lumber, grain, chemical, pulp and
paper, water, and waste water industries.
If you encounter a difficulty applying the SPL to a process measurement requirement,
or successfully apply the SPL to a "unique process" we may have never considered,
contact Milltronics or your local distributor.
