FLOW MEASUREMENT

Straight, safe and best under pressure

More than SIL – risk control starts with reliability

Any process management system is efficient with reliable instrumentation. Endress+Hauser helps you to reduce the risk in basic process control as well as safety applications with safe instrument design. For us, safety always comes first and starts with safe design and manufacturing based on certified products, people and processes. Benefits • Products: SIL devices are extensively tested and indepen- dently assessed • Process: intensively pursued functional safety development process • Sustainability: strategic functional safety management with continuous improvement Since 1999 we have extended our safety oriented instrument offering to include Safety Integrity Levels up to SIL3. Time-of-Flight level measuring instruments, vibronic point level switches and hydrostatic level devices are examples of our broad portfolio developed according to IEC 61508 and independently assessed by TÜV Rheinland. Features include self-diagnostics and proof testing that help to increase process safety and plant availability. Our certified functional safety management includes a quality and safety policy to allow permanent and systematic verification and improvement.

Need to measure bulk transfers without compromising on accuracy? The OPTIMASS 2300 Coriolis mass flowmeter from KROHNE is the answer. Based on straight tube technology from the world leader in straight tube designs, KROHNE has developed the OPTIMASS2300, an excellent solution for bulk product transfer where the highest accuracy is required. Offering outstanding performance for mass and volume flow measurement, the OPTIMASS2300 is ideal for fiscal measurement and offers flow rates from 1,560kg/h to 2,300,000kg/h with a measuring accuracy of 0.1%. The OPTIMASS2300 is also capable of high turndown ratios, keeping flow velocities low, preventing the build-up of static in hydrocarbons and presenting a real benefit for custody transfer applications, especially in the oil and gas industry. The OPTIMASS 2300 is the first Coriolis mass flowmeter available in both Duplex and Super Duplex.

Level sensor in hygienic design

For sanitary applications, WIKA has developed a magnetostrictive level sensor in hygienic design. The model FLM-H sensor, certified in accordance with 3A Sanitary Standards, meas- ures level in tanks and vessels with an accuracy of < 0,5 mm. The level is detected continuously, regardless of any physico-chemical changes of state in the media, such as foaming or boiling effects. This measuring instrument, based on the float principle, even operates reliably with CIP/SIP processes - cleaning liquids and elevated tem- peratures do not have any negative influence. The guide tube is directly welded to the process connection. This leads to a crevice-free joint between the connection and the measuring cell, without the need for additional seals. The 4 ... 20 mA output of the sensor, also available with HART protocol, transmits the signal even over long distances. The level is displayed proportional to volume or height. No calibration is required following installation.The sensor is suitable for SIL 2 (IEC 61508). Enquiries:WIKA Instruments.Tel. 011 621 0000 or email sales@wika.co.za
