10 Technical data
10.1 Additional technical data
10.1.1 Application
The Micropilot S is used for highly accurate level measurement in storage tanks and can be applied
in custody transfer applications. It meets the relevant requirements according to OIML R85 and
API 3.1B.
• The FMR531 with rod antenna is used for highly accurate measurements of very aggressive
products and in narrow nozzles.
10.1.2 Input
Measured variable
The measured variable is the distance between a reference point GRH (mounting flange) and a
reflective surface (e.g. product surface). The measured value and all parameters are displayed using
either metrical SI-units or US/UK-units (inch, ft, …).
The level is calculated based on the tank height entered.
In order to compensate for non-linear effects like movement of the tank roof, an additional
correction table (diptable) can be entered.
Measuring range see Page 18.
10.1.3 Output
Output signal • 4…20 mA with HART protocol (e.g. for multidrop connection to the Tank Side Monitor NRF
590): this version can be operated via the PC operating software FieldCare. The instrument
supports both point-to-point and multidrop operation.
For measurements with mm accuracy, the measured value must be transmitted via the HART
protocoll in order to ensure the required accuracy.
Signal on alarm Error information can be accessed via the following interfaces::
• Local display:
– Error symbol (see Page 33)
– Plain text display
– LED’s: red LED continuously on = alarm, red LED flashes = warning
• Current output
• Digital interface
Galvanic isolation 500 V towards ground.
500 V between power supply and signal.
