SITRANS Probe LU
■ Overview
■ Configuration
Parabolic mounting
4
SITRANS Probe LU is a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels, and simple process vessels.
Flat mounting and beam angle
■ Benefits
Fill
• Continuous level measurement up to 12 m (40 ft) range
• Easy installation and simple startup
• Programming using infrared Intrinsically Safe handheld
programmer, SIMATIC PDM or HART Communicator
• Communication using HART or PROFIBUS PA
• ETFE or PVDF transducers for chemical compatibility
• Sonic Intelligence signal processing
• Auto False-Echo Suppression for fixed obstruction avoidance
• Level to volume or level to flow conversion

Rungs
■ Application
The SITRANS Probe LU is ideal for level monitoring in the water
and wastewater industry, chemical storage vessels, and small
bulk hoppers.
The range of SITRANS Probe LU is 6 or 12 m (20 or 40 ft). Using
Sonic Intelligence, Auto False Echo Suppression for fixed
obstruction avoidance, and accuracy of 0.15 % of range or
6 mm (0.25 inch), the Probe LU provides unmatched reliability.
The Probe LU offers two communications options: HART or
PROFIBUS PA (Profile version 3.0, Class B).
The transducer on the Probe LU is available as ETFE or PVDF to
suit the chemical conditions of your application. As well, for
applications with varying material and process temperatures,
the Probe LU incorporates an internal temperature sensor to
compensate for temperature changes.
• Key Applications: chemical storage vessels, filter beds, liquid
storage vessels
