graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific

Description
2
The SITRANS LU180 is an ultrasonic level monitor combining sensor and electronics in a
single package. It is designed to measure liquid levels in open or closed vessels. The process
part (sensor) is PVDF, allowing the SITRANS LU180 to be used in a wide variety of industries,
especially food and chemical.
The sensor houses the ultrasonic transducer and temperature sensing element. The SITRANS
LU180 emits a series of ultrasonic pulses from the transducer. Each pulse is reflected as an
echo from the material and sensed by the transducer. The echo is processed by the SITRANS
LU180 using Siemens' proven ‘Sonic Intelligence’ techniques. Filtering is applied to help
discriminate between the true echo from the material, and false echoes from acoustical and
electrical noises and agitator blades in motion. The time for the pulse to travel to the material
and back is temperature compensated and then converted into distance for the mA output.

It is advisable to keep the device away from high voltage or current runs, contactors and SCR
control drives.
3.2 Location
Locate the SITRANS LU180 so that it
will have a clear sound path that is
perpendicular to the liquid surface.
The SITRANS LU180 sound path should not
intersec
t the fill path, rough walls, seams,
rungs, etc.

5.2 Calibration
The calibration of the mA output may be done such that its span will be either proportional or
inversely proportional to the material level.
Note
The 4 and 20 mA levels may be calibrated in any order.
Proportional span
Inversely proportional span
high level = 20 mA
high level = 4 mA
low level = 4 mA
low level = 20 mA
5.3 Calibration: reference method
1. Adjust the material level (or target) to the desired distance from the sensor face.
2. Press the “4” or “20”key (as appropriate) to view the stored distance associated with that
mA output value.
3. Press the key a second time to set the new distance reference.
4. After viewing or calibrating, the unit operation automatically reverts to the Run mode (6
sec). The calibration value is referenced from the face of SITRANS LU180 sensor, in the units
displayed.
