  7. Interface Solutions Challenges in Level Measurement Small tank (fast level change) Condensate Conductivity 1…100 μ s/cm Foam formation Vapor pressure Low DK (> 50mbar / +20°C, > 0.73psi / +68°F) Pressurization Small tank (blocking distance) Viscosity Changing media (density) Unaffected by obstacles Hygienic application (cleanability) Simple maintenance (disassembly) Build-up formation Slide 7 05/28/2014 PS

  8. Interface Solutions Technology Evolution in Level Measurement  Moving parts can fail due to build-up  Medium properties affect accuracy  May need a lot of maintenance to ensure reliable operation Modern technology: safe, reliable, maintenance friendly Slide 8 05/28/2014 PS

  9. Interface Solutions Displacer Replacement Replace with • Density changes => Displacer has to be adjusted • Build-up has more influences on displacer than on Guided Radar • Displacer are extremely affected by vibration • due to the big displacement body over the whole measurement range and due to the small mechanical movement of the torque tube Slide 9 05/28/2014 PS

  10. Interface Solutions The Principle – Time of Flight (ToF)  Emission of ultrasound- or microwave-pulses  Reflection of the pulses from the product surface  Receiving of the reflected pulses  Measurement of the T ime o f F light emitting calculation of the distance between the device and the product surface by receiving 00.40 d = c 2 Slide 10 05/28/2014 PS

  11. Interface measurement – Guided Radar • Simultaneous measurement of level + interface or thickness of the oil layer • Independent of temperature and density changes • Measurement in high P and T applications • Emulsion layer max. 50mm • Delta DC min. 10 • DC of upper fluid max. 10 • Upper thickness > 60mm • DC upper medium must remain
