Probe LU240
SITRANS Probe LU240 ultrasonic level transmitter with HART, 4 to 20 mA is ideal for level,
volume, and volume flow measurements. It works with liquids, slurries, and bulk materials up to 12 meters (40 feet).
The transducer is available as ETFE (ethylene-tetrafluoroethylene) or PVDF (polyvinylidene
fluoride) to suit the chemical conditions of your application. For applications with varying
temperatures, the SITRANS Probe LU240 incorporates an internal temperature sensor to
compensate for temperature changes.
The self-cleaning face of SITRANS Probe LU240 is resistant to build-up and condensation
and has field-proven Process Intelligence signal processing. Together, they provide long
term, low maintenance level, volume, and volume flow measurement in difficult applications
SITRANS Probe LU240 is designed to measure Level, Volume, or Volume flow in a variety
of applications:
● Storage type vessels
● Simple process vessels with some surface agitation
● Liquids
● Slurries
● Bulk solids
● Open channels
Pre-defined vessel shapes can be used to convert level measurements to volume.
Volume flow
For an open channel system (such as a Parshall flume, V-notch weir, or other open channel
device), volume flow can be measured by using integral pre-defined flow structures.
Custom level to output
A customized level-to-output linearization function is available to calculate volume or volume
flow, for vessels not included in the pre-defined shapes as noted above.
