Siemens Sitrans LUT400 series ultrasonic controllers

Siemens has released a series of ultrasonic controllers with 1 mm measuring accuracy. The Sitrans LUT400 series controllers are compact, single-point, long-range ultrasonic controllers for continuous level or volume measurement of liquids, slurries and solids. Importantly, they deliver high accuracy monitoring of open channel flow.

They are also suited to key applications such as wet wells, reservoirs, flumes/weirs, chemical storage, liquid storage, hoppers, crusher bins and dry solids storage. The Sitrans LUT400 comes in three different models to match the application, level of performance and functionality required.

The LUT420 level controller measures the level or volume of liquids, slurries and solids, and conducts basic pump control functions and basic data-logging capabilities.

The LUT430 is a level, volume, pump and flow controller. It includes all the features of the LUT420 plus a full suite of advanced pump control and alarm functionality, open channel flow monitoring, and has basic flow data-logging capabilities.

The Sitrans LUT440 is a high-accuracy OCM. It includes all the features of the LUT430 and provides an accurate of ±1 mm within 3 m. It has a full suite of advanced control functions as well as enhanced flow-logging capabilities.
