round up ANALYTICAL INSTRUMENTATION

Goodbye to the Manometer Needle Instrotech is offering Keller’s electronic ECO 2 manometer – an instru- ment that can perform all standard measuring jobs at an exceptional- ly low price. Compared to its mechanical predecessors. Keller’s digital technology offers high resolution, excellent repeatability at very similar prices. The ECO 2’s dual display updates twice every second, showing the measured value and the minimum or maximum value attained. As a special feature, the ECO 2 has a Zero Tare feature, allowing the user to set the zero to any pressure, so that the manometer will then always show deviations from the Zero Tare value as the actual value. The user-friendly two-key operating system provides access to the entire range of functions: the stored MAX/MIN can be erased and reset to zero, or the device can be switched to continuous mode. In continuous operating mode, the battery has capacity for up to 1 000 hours. The ECO 2 electronic manometer has a standard automatic switch-off time of about 15 minutes

High performance in applications with limited mounting space WIKA’ s model FLC-FC cone flow meter is an advanced application of differential pressure technology. Its char- acterisation of the flow profile enables reliable measure- ment even under the most difficult conditions. Thanks to its design, the cone flow meter is ideally suited for applications with limited mounting space. It offers a wide and stable turndown and, at the same time, a high ac- curacy and repeatability. The FLC-FC cone flow meter is produced in accordance with the ISO 5167 reference standard. Part 5 of this standard covers the topics of in- stallation and operating conditions and gives further infor- mation for calculating the flow rate and its uncertainties. • Low maintenance effort: The conical primary ele- ment has been designed so that its edges are pro- tected from particles in the medium. Therefore, the cone flow meter has a very long service life, even in applications with abrasive media • Short upstream and downstream pipes possible: The optimised flow profile prevents asymmetric flow effects and enables operation with very short upstream and downstream pipes Enquiries:WIKA Instruments.Tel. +27 11 621 0000 or email sales.za@wika.com

after the last key function, this extends the battery life where continuous operation is not required. The easy- to-handle ECO 2 is available with two practice-based measuring ranges of -1…30 bar and 0…300 bar in the compensated temperature range from 0 to 50°C, the economically priced standard manometer offer typical overall accuracy of 0,5% FS (Full Scale).
