    This document provides an overview of the user responsibilities for installation and operation of the Rota Yokogawa RAKD 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 64: A1.2.2 Diagnostic Response Time

    Maintenance information can be found in section 6, Maintenance of the User’s Manual Model RAKD Small Metal ROTAMETER, IM 01R01B30-00E-E. If repair is to be performed with the process online the Rota Yokogawa RAKD variable area flow meter will need to be bypassed during the repair. The user should setup appropriate bypass procedures for that.

  • Page 65: A1.2.6 Startup Time

    The expected lifetime of the Yokogawa Rota Yokogawa RAKD variable area flow meter is 10 years. The reliability data listed in 2.7 is only valid for this period. The failure rates of the Rota Yokogawa RAKD variable area flow meter may increase sometime after this period. Reliability calculations based on the data listed in A1.2.7 for Rota Yokogawa RAKD variable area flow meter lifetimes beyond 10 years may yield results that...
