According to Siemens Industry Automation Division, their new Sitrans LUT400 series ultrasonic controllers offers one-millimeter (0.04-inch) 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.
The controllers are available in three models: the Sitrans LUT420 Level Controller, 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 series is suitable for an array of applications, including those in water/wastewater treatment facilities, manufacturing processes, and industrial storage.
With 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 Sitrans LUT400 series controllers feature an intuitive user interface. The controllers 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, Siemens echo processing technology for ultrasonic level instruments, continuously evaluates and adjusts for noise level and changing process conditions. All three models are compatible with the full line of Echomax ultrasonic transducers from Siemens. The Sitrans LUT400's datalogging capabilities allow users to store and review datalogs or transfer them to a computer. In addition to local programming, the controllers also support remote configuration and diagnostics with Siemens Simatic PDM (Process Device Manager), Emerson AMS, FC375/475, or FDTs (such as PACTware) using Siemens DTM.
