Example 1 - Level Measurement 
Material Level 
This is the most common application of the SITRANS LU01 level monitor. 
For this example we'll assume the following: 
one 30 m high cement silo is to be monitored. 
the maximum vessel filling rate is 0.08 m per minute. 
alarm indicators are required when the cement level exceeds 25 m or falls below 
10 m. 
filling equipment is to be automatically deactivated at 27 m. 
in the event of a measurement difficulty, failsafe operation is to be activated in 2 
minutes. 
if the difficulty doesn't subside, the filling process is to be stopped before a spill 
occurs. 
an XLT-30 transducer is mounted with its face flush with the top of the vessel. 
a TS-3 temperature sensor is connected to the Temp Sensor 1 terminals.
