Sitrans LUT400 ultrasonic controller for level measurement works with liquids, solids, and slurries.Siemens Industry Automation Division has announced the Sitrans LUT400 series ultrasonic controllers with one-millimeter (0.04-inch) measuring accuracy. Siemens claims these new controllers offer the highest accuracy available on the market to ensure consistently precise measurements.

The compact, single point ultrasonic controllers continuously monitor and control level in liquids, solids, or slurry applications for a wide range of industries. The controllers 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 company says that when using these new controllers, operators can be confident of level or flow measurements thanks to Sitrans LUT400’s patented filters and algorithms. The high accuracy of these new 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 Sitrans LUT400 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 controllers feature an intuitive user interface so they can be programmed in minutes using the graphical quick-start wizards. The backlit display is easy to read in all lighting conditions. Sonic Intelligence, Siemens’ echo processing technology for ultrasonic level instruments, continuously evaluates and adjusts for noise level and changing process conditions.
