(such as solenoid valves). Alternating magnetic fields (≥ 10Hz) as well as homogeneous, static magnetic fields (in the area of the RAMC), like the geomagnetic field have no influence. Asymmetric ferromagnetic bodies of considerable mass (e.g. steel girders) should be kept at a distance of at least 250 mm from the RAMC.
Page 17: Installation
Centre gaskets and tighten nuts with a torque appropriate for the pressure range. If contamination or soiling of the RAMC is to be expected, a bypass should be installed to allow the removal of the instrument without interruption of the flow.

Page 129: Appendix 2. Safety Instrumented Systems Installation
This document provides an overview of the user responsibilities for installation and operation of the Rota Yokogawa RAMC variable area flow meter in order to maintain the designed safety level. Items that will be addressed are proof testing, repair and replacement of the flow meter, reliability data, lifetime, environmental and application limits, and parameter settings.
Page 130: A2.2.2 Diagnostic Response Time
Perform a two-point calibration of the variable area flow meter RAMC Force the variable area flow meter RAMC to go to the high alarm current output and verify that the analog current reaches that value. Note: it is only possible to set RAMC to the high alarm current mode via HART communication! This tests for compliance voltage problems such as a low loop power supply voltage or increased wiring resistance.
Page 131: A2.2.5 Repair And Replacement
Maintenance information can be found in section 8, Maintenance of the User’s Manual Model RAMC Short Stroke ROTAMETER, IM 01R01B02-00E-E. If repair is to be performed with the process online the Rota Yokogawa RAMC variable area flow meter will need to be bypassed during the repair. The user should setup appropriate bypass procedures for that.

Manual, Model RAMC Short Stroke ROTAMETER IM 01R01B02-00E-E. A2.2.12 Application limits The application limits of the Rota Yokogawa RAMC variable area flow meter are specified in the User’s Manual, Model RAMC Short Stroke ROTAMETER, IM 01R01B02-00E-E. If the flow meter is used outside of the application limits the reliability data listed in A2.2.9 becomes invalid.
