Remaining Vessel Capacity
To perform a volume conversion for the preceding example, complete the following
programming.
Volume Parameter Settings
* 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 a few ways in which the SITRANS LU01 can be
applied to process measurement requirements.
The SITRANS LU01 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 SITRANS LU01 to monitor specific processes.
Siemens 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 SITRANS LU01 to a process measurement
requirement, please contact Siemens Milltronics or your local distributor.
Communication Support
With the addition of a Siemens Milltronics Smartlinx ® protocol specific plug-in
communications module, the SITRANS LU01 is compatible with popular industrial control
system standards. Supported protocol include PROFIBUS DP, Allen-Bradley® Remote I/O,
Modbus® RTU, and DeviceNet
TM .
Alternatively, the SITRANS LU01 provides digital communication to a peripheral device,
such as a computer or PLC, in one of three modes via the communication port, terminals
