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

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

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

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

FMP55 – probe selection

Coaxial probes:  Measuring range up to 6m (20ft)  Independent from mounting:

• No influences from

nozzles

• No influences by
• bstacles, 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 Rod probes:

• Measuring range

up to 4m (13ft)

• For the mounting in

bypass or stilling well

• Very low influence by
• bstacles, fixtures and

fittings, if the distance is  300mm (11.8")

Interface Application Challenges

• All Oil wells need to be tested periodically for proper allocation
• Each well is put on test periodically to calculate it’s yield
• Done in a horizontal separator called a Free Water Knock Out (FWKO)
