Ultrasonic controller for level measurement

12 June 2012

Siemens Industry Automation Division has introduced the Sitrans LUT400 series ultrasonic controllers which feature a measuring accuracy of 1mm. The compact, single point ultrasonic controllers continuously monitor and control level in liquids, solids, or slurry applications for a range of industries.

The controllers are available in three models: the Sitrans LUT420 level vontroller, Sitrans LUT430 level, pump, and flow controller, and Sitrans LUT440 high accuracy open channel monitor (which also provides a full suite of advanced level, volume, and pump controls).

The new controllers are said to give operators greater confidence regarding level or flow measurements owing to Sitrans LUT400's patented filters and algorithms. The high accuracy of these new controllers results in cost-effective operations, says the company. Inventory monitoring is precise, processes are better controlled, and expensive spill cleanups can be avoided.

With energy cost reduction strategies growing in importance, the Sitrans LUT400 controllers are also sesigned to 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 Sitrans LUT400 series controllers feature an intuitive user interface. They 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. Sonic Intelligence, the company’s own echo processing technology for ultrasonic level instruments, continuously evaluates and adjusts for noise level and changing process conditions.
