Example 1 - Level Measurement
Material Level
This is the most common application of the SPL 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 terminals.
