    (e.g. steel girders) should be kept at a distance of at least 250 mm from the RAMC. To avoid interference, the distance between two adjacent RAMC must be at least 300 mm (see Fig. 2-1). (212) (300) Fig.

  • Page 15: Installation

    Center 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.

    Please regard the drawings on the following pages. On the rear of the RAMC are two openings for cable glands for round cables with a diameter of 6 to 9 mm (not for Ex-d-type option / F1). Unused glands must be closed with a blind plug M16x1.5. (housing type 90) or with a blind plug M20x1.5 (housing type 91).

    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 139: A2.2.2 Diagnostic Response Time

    A2.2.5 Repair and replacement Maintenance information can be found in chapter 8. If repair is to be performed with the process online RAMC variable area flow meter will need to be bypassed during the repair. The user should setup appropriate bypass procedures for that.

    The expected lifetime of the Yokogawa Rota Yokogawa RAMC variable area flow meter is 10 years. The reliability data listed in A2.2.7 is only valid for this period. The failure rates of the Rota Yokogawa RAMC variable area flow meter may increase sometime after this period. Reliability calculations based on the data listed in A2. 2.7 for Rota Yokogawa RAMC variable area flow meter lifetimes beyond 10 years may yield results that are too optimistic, i.e.
