The Siemens SITRANS LUT400 series controllers are compact,
single point, long-range ultrasonic controllers for continuous
level or volume measurement of liquids, slurries, and solids,
and high accuracy monitoring of open channel flow.
•• Small 1/2 DIN enclosure [144 h x 144 d x 146 w mm
(5.7 x 5.7 x 5.75 inch)] with standard universal mounting
bracket for wall, pipe, and DIN rail, plus an optional panel
mount
• Easy to use HMI display with local four-button programming,
menu-driven parameters, and Wizard support for key applications
• English, German, French, Spanish, Chinese, Italian, Portuguese,
and Russian texts on the HMI.
• Level, Volume, OCM Flow monitoring
• Three relays combined with a suite of pump, alarm, and relay
control features
• HART Communications
• EDDs for SIMATIC PDM, AMS Device Manager, and Field
Communicator 375/475, plus DTMs for FDTs (Field Device
Tools)

The SITRANS LUT400 comes in three different models, depending
on the application, level of performance and functionality
required:
• SITRANS LUT420 Level Controller: Level or volume
measurement of liquids, slurries, and solids, as well as basic
pump control functions, and basic data logging capability
• SITRANS LUT430 Level, Pump and Flow Controller: Includes
all features of the LUT420 plus a full suite of advanced pump
control and alarm functionality, open channel flow monitoring,
and basic flow data logging capability
• SITRANS LUT440 High Accuracy OCM: Our most featured,
highest accuracy model. Includes all features of the LUT430,
plus the industry’s best accuracy (± 1 mm within 3 m), full suite
of advanced control functionality, and enhanced flow logging
capability
• Key applications: wet wells, reservoirs, flumes/weirs, chemical
storage, liquid storage, hoppers, crusher bins, dry solids
storage
