Introduction
SITRANS LU01
The SITRANS LU01 is an ultrasonic long-range level monitoring system for liquids and
solids. SITRANS LU01 level monitor uses one Siemens Milltronics ultrasonic transducers
(ordered separately) to accurately monitor material levels without material contact.
The SITRANS LU01 transmits electronic pulses to each connected ultrasonic transducer.
The transducer converts the electronic pulses to ultrasonic pulses which are emitted
from the transducer face in a narrow beam. The SITRANS LU01 measures the time from
the pulse emission, to reception of the reflection (echo) from the material. Using the time
measured, the SITRANS LU01 calculates the distance from the transducer face to the
material.
The distance calculation depends upon the sound velocity within the vessel. When an
Echomax transducer is used, variable air temperatures are automatically compensated.
For superior air temperature compensation, a Siemens Milltronics TS-3 temperature
sensor may be used for each vessel. A simple calibration feature compensates for
homogeneous atmospheres other than air.
The SITRANS LU01 uses Siemens Milltronics patented Sonic Intelligence®echo
processing. Sonic Intelligence provides high measurement reliability, regardless of
changing conditions within the vessel monitored. By using ultrasonic echo ranging
principles with Sonic Intelligence and velocity compensation, the SITRANS LU01 provides
outstanding measurement accuracy, usually within 0.25% of range.
Note:
• The SITRANS LU01 is to be used only in the manner outlined in this instruction
manual.
• This product is intended for use in industrial areas. Operation of this equipment
in a residential area may cause interference to several frequency based
communications.
