INSTRUMENTATION • ELECTRONICS
choose specific sensors, the portal now asks a series of straightforward questions about the process to be measured, including pipe material, pipe diameter, wall thickness and fluid temperature. It even offers a pre- determined selection of ranges for questions requiring a numerical response. With this information in hand, the portal identifies exactly which sensors and accessories should be ordered - eliminating the potential for costly mistakes.
DESIGNED TO BE USER FRIENDLY The new solution has been designed to make installation and configuration easier and more efficient, even for those previously unfamiliar with clamp-on technology. The basis for this is the transmitter’s advanced human machine interface (HMI), which features a customisable 240x160 graphic display - one of the largest of its kind - and four capacitive navigation keys, along with a comprehensive set of help texts that clearly define every individual menu item. To ensure that the meter is optimally configured to
measure a particular application, the HMI walks the end user through every step of the installation process via a series of setup wizards, including: sensor setup; process values; communications; and copy setup. Correcting for non-ideal piping conditions is another critical step in configuring a clamp-on meter, and the
Sitrans FS230 streamlines this process as well. Its pipe configuration wizard allows the user to select from multiple anomalies – e.g. 90° elbows or valves not far upstream – and input the anomaly’s distance from the sensors. The meter then automatically compensates for any impact of the anomaly on the flow profile, which might otherwise result in measurement errors and a considerable reduction in accuracy. Over the past five decades, clamp-on flowmeters
have developed into an exceptionally well-rounded option for measuring liquid flow in industrial applications. They perform with high levels of accuracy and repeatability, require almost no maintenance and are versatile enough for use with a variety of conductive and non-conductive fluids. Most importantly, they offer the flexibility for installation in virtually any location at any time. To ensure that the process industries fully embrace
these advantages in the years to come, the newest clamp-on meters must be designed with the customer in mind. Next-generation systems are simplifying complexities, reducing start-up times and making clamp-on ultrasonic flow technology a wiser investment than ever before. n

ACTUATORS for HEATING/COOLING and METERING APPLICATIONS
UMA’s compact electric actuator ranges offer precise, robust and reliable flow control solutions for chemical, food and other industries. Applications include demanding temperature control systems, for example preheating and cooling systems, and fluid metering duties. AUMA offers two families of compact actuators: Basic Range and Smart Range. Both ranges are designed for harsh industrial environments. Their compact design makes them ideally suitable for space constraints and small valves. The Basic Range comprises SBA linear actuators and ED/EQ part-turn actuators. They offer simple control and essential functions as well as feedback signals, paired with robust design. SBA linear actuators provide high positioning accuracy and are suited for modulating applications.

AUMA SDL linear actuators provide high positioning accuracy for modulating applications, for example in heating or cooling circuits
The Smart Range includes SDL/ SDG linear actuators, SVC globe valve actuators and SGC part-turn actuators. All have variable-speed motors that provide
soft starts and stops, ensuring gentle treatment of mechanical components. Variable-speed operating profiles help to avoid critical pressure surges and cavitation. Parameters can be set via software, and both Modbus RTU and Profibus DP interfaces are available.
SDL/SDG linear actuators feature
low energy consumption, making them particularly suited to remote sites and solar PV systems. They are also insensitive to voltage fluctuations. AUMA’s compact linear actuators cover thrusts of 0.6-25kN and strokes of 35-300mm. Part-turn actuators are available for torques of 25-1,000Nm. Globe valve actuators offer torques of 10-100Nm, with strokes from 60-70mm. n
