Siemens Industry: Ultrasonic Controllers for Level Measurement

Sept. 7, 2012
The Sitrans LUT400 series ultrasonic controllers have one-millimeter (0.04-in.) measuring accuracy.

The compact, single point ultrasonic controllers continuously monitor and control level in liquids, solids, or slurry applications for a wide range of industries. They are available in three models: the LUT420 Level Controller, LUT430 Level, Pump, and Flow Controller, and LUT440 High Accuracy Open Channel Monitor (which also provides a full suite of advanced level, volume, and pump controls). The series is suitable for an array of applications, including those in water/wastewater treatment facilities, manufacturing processes, and industrial storage. The high accuracy of the controllers results in cost-effective operations: inventory monitoring is always precise, processes are better controlled, and expensive spill cleanups can be avoided. With energy cost reduction strategies growing in importance, the controllers assist water/wastewater facilities in reducing their overall energy expenses with a real-time clock and energy saving algorithms for reducing pump operations during peak energy periods. The units feature an intuitive user interface and can be programmed in less than one minute using the graphical Quick Start Wizards. The backlit display is easy to read in all lighting conditions. Echo processing technology for ultrasonic level instruments continuously evaluates and adjusts for noise level and changing process conditions. The controller's datalogging capabilities allow users to store and review data logs or transfer them to a computer.
