Appendix Micropilot S FMR531 with HART/4...20 mA
94 E Hauser
Micropilot S radar devices continuously monitor the compliance with accuracyrequirements for
custody transfer measurements according to OIML R85. If, for example, the accuracy cannot be
maintained due to quick surface movements, this is reported via a separate alarm in the local display
(displays "#"- symbols) and via digital communication.
11.3.6 Definition of terms
For definitions and procedures please refer to the following documents:
• Manual of Petroleum Measurement Standards, Chapter 3 - Tank Gauging,
Section 1.B - Standard Practice for Level Measurement of Liquid Hydrocarbons in Stationary
Tanks by Automatic Tank Gauging, American Petroleum Institute, second edition, 2001
• OIML R 85, Organisation Internationale de Métrologie Légale, International Recommendation R
85, edition 1998 (E).
11.3.7 Integrated in tank gauging system
The Hauser Tank Side Monitor NRF590 provides integrated communications for sites with
multiple tanks, each with one or more sensors on the tank, such as radar, spot or average
temperature, capacitive probe for water detection and/or pressure sensors. Multiple protocols out
of the Tank Side Monitor guarantee connectivity to nearly any of the existing industry standard tank
gauging protocols. Optional connectivity of analog 4...20 mA sensors, digital I/O and analog output
simplify full tank sensor integration. Use of the proven concept of the intrinsically safe HART bus
(HART multidrop) for all on-tank sensors yields extremely low wiring costs, while at the same time
providing maximum safety, reliability and data availability.
