Performance characteristics
Reference operating
conditions According to OIML R85:
• Temperature = –25…+55 °C (-13…+131 °F)
• Atmospheric pressure
• Relative humidity (air) = 65 % ±15%
• Medium properties: e.g. medium with good reflectivity and calm surface.
• Tank diameter: signal beam hits the tank wall only at one side.
Note!
No major interference reflections inside the signal beam.
Maximum measured
error Absolute accuracy: 0.5 mm (2
σ
value)
Inventory Control Versios: ±3 mm
Proof of accuracy for
custody transfer
versions The accuracy of each Micropilot S is established through a calibration
certificate that records the absolute and relative error at 10 equidistant points
during the final test. A Laser Interferometer (Jenaer Messtechnik ZLM 500)
with an absolute accuracy of 0.1 mm is used as a reference for the free space
measurements with FMR 533.
Each Micropilot S is delivered with the PTB and NMi type approval. Additional
initial factory verifications for custody applications are available on demand
for all radar instruments FMR 53x.
Maximum fill speed By the first pass trough of measuring range: 100 mm/min., thereafter
unlimited.
Non-repeatability 0,3 mm (1/64")
Hysteresis 0.3 mm
Resolution digital: 0.1 mm
analogue: 0.03 % of measuring range
Settling time Typical 15 sec
Long-term drift The long-term drift is within the specified accuracy.
Influence of ambiente
temperature Within the specified accuracy according to OIML R85.
Software reliability The software used in the radar instruments FMR 53x fulfills the requirements
of OIML R85. This particularly includes:
• cyclical test of data consistency
• non-volatile memory
• segmented data storage
The radar instruments Micropilot S continuously monitor the compliance with
accuracy requirements for custody transfer measurements according to
OIML R85. If the accuracy cannot be maintained, a specific alarm is
generated on the local display and via the digital communication.
