Sitrans FUT1010 is available in two versions: one for gas and one for liquids measuring viscosities up to 2,800 cSt (centistokes). Its versatility makes it suitable for up-, mid- and downstream measurement tasks, such as check metering, process control and underground storage surveillance. Since it can be installed on small as well as large pipes it is suitable for many applications, including custody transfer applications that require laboratory calibration.

SIEMENS Industry Automation Division has developed the Sitrans FUT1010, an ultrasonic flowmeter for the hydrocarbon industry. It features the nearly maintenance- free TransLoc mounting system, which allows the transducers to be mounted on the outside of the pipe, preventing contact with the medium. This approach allows the externally mounted transducers to be calibrated for higher accuracy, and also has the additional benefit that it alleviates clogging of cavities by high paraffin liquids, which is typically seen in conventional flowmeters used in hydrocarbon applications. TransLoc ensures less maintenance and downtime, leading to low cost of ownership and improved return on investment. The combination of WideBeam ultrasonic transit time flow technology with the delivery of the entire meter run, including the segments for upstream, downstream and the flow conditioner, can be calibrated to American Petroleum Institute and American Gas Association specifications. It also ensures that the Sitrans FUT1010 achieves highly accurate flow measurement.

Easy tool change tube mill THE Oto 40616 ETC (easy tool change) tube mill includes flexible forming as conceived by Nakata. Forming rolls need not be changed, but simply adjusted according to what is required as a function of tube diameter. Finishing and sizing sections are designed with interchangeable 4-roll stands. The tooling change has been designed to minimise change-over time and operator involvement throughout the tube mill. Using existing forming concepts, the company has automated the tooling pick and set-up operations. In the finishing and sizing, the quick change-over does not occur by replacing the entire stand (as typically executed on smaller mills), but by swapping the assembly, including rolls, shafts, bearing blocks and side rolls from the top of the stand. All driven stands are mounted to the mill base and universal joints are provided with an automated engagement/ disengagement hydraulic system from the

mill shafts allowing for the roll, bearing block, shaft, and side rolls (if provided) to be moved in and out of the stands, which are designed with an opening at the top to enable the change-over operation via crane. Jacks and absolute encoder for top shaft adjustment are part of the removable assembly. Adjustments on the roll, shafts, and bearing block assembly are performed through electric gear motors and absolute encoders. The entire change-over operation is automatic, so operators are simply involved in the lifting of the roll assembly in one motion. The Oto 40616 ETC tube mill comes with a second set of shaft, bearing block and side roll assemblies to enable off-line roll change-over. Extra shafts and bearing blocks may be purchased, which can be permanently assembled to the rolls for even faster roll replacement. A special tool designed to help the off-line roll change-over is also offered. Oto Mills SpA – Italy Fax: +39 0522 964188 Website: www.otomills.com
