round up FLOW MEASUREMENT + INSTRUMENTATION

Evolution in gas measurement Ultrasonic gas flow meter

As the follow-up to the successful FLOWSIC600, the FLOWSIC600- XT ultrasonic gas flow meter is setting new standards in its market segment. With four device variants available, the FLOWSIC600-XT can take on any challenge – whether it is being used as a stand-alone de- vice or as part of a system solution – and delivers optimum measure- ment performance.The FLOWSIC600 already provided absolute long- term stability in extreme ambient conditions, and now the four device variants in the FLOWSIC600-XT product family combine the features of their predecessors with unprecedented usability. Throughout their service life, they meet every requirement for safe, stable and custody transfer gas quantity measurement. The FLOWSIC600-XT’s trend-setting design houses some impres- sive and innovative internal features: i-diagnostics for smart application diagnostics with a built-in solution wizard and PowerInTechnology which continues to take measurements for up to three weeks in the event of a mains voltage failure. The FLOWSIC600-XT features an ideal combina- tion of maximum measurement accuracy, long-term stability and unpar-

alleled operational safety, yet is not at all compli- cated to use. The ultrasonic gas flow meters in the FLOWSIC600-XT product family are designed for custody transfer gas quantity measurements,

satisfy the requirements of every cur- rent national and international stand- ard, and are exceptionally simple to integrate into conventional system environments. Enquiries: Doreen Cronje.Tel. +27 (0) 11 472 3733 or email Doreen. Cronje@sickautomation.co.za

High-temperature thermocouple with added protection from sapphire glass

The newTC84 high-temperature thermocouple from WIKA features the highest safety and a long service life. Its resilience is based on a sap- phire protection tube in combination with a two-stage safety chamber. The measuring instrument is also available in an ATEX and also an IECEx certified version. Typical applications for the TC84 are gasification reac- tors with process temperatures up to 1 700°C and pressure loads up to 65 bar or sulphur recovery units. In the patented design of the meas- uring instrument, the precious-metal thermocouple is shielded from damaging process influences through two protection tubes - through an external tube from ceramic and an internal tube from monocrystalline sapphire glass, which effectively delays the poisoning of the thermo- couple. In the event of any failure, the dual sealing system of the safety chamber prevents the escape of toxic media. The construction of the thermocouple also follows economical principles. ATC84, damaged fol- lowing extreme loading, can be repaired through the exchange of the wetted parts; a completely new purchase is therefore not required. The sapphire protection tube also eliminates the need for expensive purging with inert gas, for example, to protect the thermocouple.
