12.5 µs cycle time, continuously maintained from the PLC to the I/O signals: This is eXtreme Fast Control – XFC. With the presentation at Hannover Messe 2012, Beckhoff was underlining its technological leadership in fast control technology. The components for this record-breaking system are: a high-performance CPU – a Beckhoff Industrial PC with control software to match – TwinCAT 3; ultra-fast I/O components – with 1 µs latency; and naturally the fast Industrial Ethernet system – EtherCAT.
“When we first presented EtherCAT in 2003, the performance of this new fieldbus technology was still miles ahead of the controller capability of the time. With TwinCAT 3 and the current IPC CPUs the gap is closing, although it's still not possible to foresee when we will be able to make the maximum EtherCAT data throughput fully usable for machine controllers”, says Dr. Dirk Janssen, Manager Software Development at Beckhoff and one of the inventors of EtherCAT. “With the 12.5 µs presentation we were showing what the Beckhoff system is capable of together with our EtherCAT Terminals.” Dirk Janssen says that the bus cycle time, while exciting, is actually in itself not decisive: “A fast fieldbus only becomes a fast control system with a capable controller and ultra-fast I/O components. And only with EtherCAT can the highest performance of the fieldbus be implemented continuously through to the I/O signals: All technologies that rely on bus couplers with a separate, local I/O bus suffer here from system-related disadvantages.”

When you need precision gas mass flow control of expensive process gases, where minimal pressure drop is a key consideration for cost savings and efficiency, the SmartTrak® 140 controls up to 500 slpm with an ultra-low ΔP of 4.5 psid (310 mBard) much better than typical ΔP values of 25 psid (1700 mBard) for equivalent mass flow controllers on the market.
Following the successful launch by Endress+Houser in 1998,more than 220,000 installed guided radar measuring points . The new Levelflex family opens another chapter in the success story of guided radar. The family comprises eight products - from the standard product for basic applications through to high-performance versions for sophisticated use in high-pressure and high-temperature conditions, complex interface measurement or applications in gases and steams. The Levelflex family facilitates the safe and efficient control of levels and inventories in your application.

The MC-RTU flow analyzer provides continuous digital display of flow rate and total flow of liquids or gases. When combined with a NUFLO Turbine flow meter, selected for a particular application, the MC-RTU becomes an accurate flow rate meter and flow totalizer. Low power microprocessor technology provides the MC-RTU with long life and reliability. Easily programmable using the front four-wide keypad, the MC-RTU can be programmed to display a wide variety of total flow and flow rate volumetric units. Two types of packaging and mounting options are available to suit many different applications including outdoor and hazardous locations.
