6 Interface Solutions Our Level and Pressure Product Portfolio Point level detection Continuous level measurement Interface measurement Tank gauging Pressure / Differential Pressure Density measurement Slide 6 03/18/2014 PS

7 Interface Solutions Challenges in Level Measurement Condensate Small tank (fast level change) Foam formation Conductivity 1 100μs/cm Vapor pressure (> 50mbar / +20 C, > 0.73psi / +68 F) Low DK Small tank (blocking distance) Pressurization Changing media (density) Viscosity 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 Time of Flight calculation of the distance between the device and the product surface by emitting receiving 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

15 Animation FMP55 SensorFusion - Multiparameter

16 FMP55 Multiparameter SensorFusion Technology +/- 2 mm accuracy (highest accuracy available on the market) Combination of guided radar and capacitance probe for interface measurement even in emulsion layers Up to 3 measurements (level, interface, upper phase thickness) with one device PTFE coated probe Measuring range up to 10m (33ft) Temperature: C ( F) Pressure: bar ( psi)

17 Key Features Reliable measurement even for changing product and process conditions HistoROM data management for easy commissioning, maintenance and diagnostics Highest reliability due to Multi-Echo Tracking Hardware and software developed according to IEC (up to SIL3) Seamless integration into control or asset management systems Easy proof test for SIL The HistoROM is fixed in the housing (can not be lost or forgotten )

18 FMP55 probe selection Rod probes: Measuring range up to 4m (13ft) For the mounting in bypass or stilling well Very low influence by obstacles, fixtures and fittings, if the distance is 300mm (11.8") Coaxial probes: Measuring range up to 6m (20ft) Independent from mounting: -No influences from nozzles -No influences by obstacles, fixtures and fittings in vessel Rope probes: Measuring range up to 10m (33ft) For the mounting in bypass or stilling well At narrow installation conditions, e.g. at low ceiling space

19 Interface Solutions FMP55 operation methods (*) Default (**) must be programmed (***) wet calibration > 2m/6.6ft Standard (*) Always better than TDR alone is constant and known** Build-up Diagnostics of heavy build-up is constant and known** Specific capacitance (pf/m) is known (factory calibrated < 2m/6.6ft probe length)*** Emulsion layer Works even when never a clear cut interface exists is constant and known** Specific capacitance (pf/m) is known (factory calibrated < 2m/6.6ft probe length)*** Special: Auto DC calc. Accurate measurement with variable (unknown) Specific capacitance (pf/m) is known (factory calibrated < 2m/6.6ft probe length)*** Clear interface Level and interface with TDR Specific capacitance (pf/m) is permanently calibrated Level and interface with TDR Redundant interface detection with capacitance measurement Level with TDR Interface with capacitance Level and interface with TDR is continuously calculated Emulsion/Damping 08/24/2010 Build-up PS Slide 19 As with TDR only In case of emulsion only moderate effect due to previous recalibrated capacitance value Message maintenance required ís generated (for clear interface only) Level with TDR Interface with capacitance For level as with TDR alone For Interface as with capacitance alone Not recommended
