    Dangers during commissioning 1.2.4.2. Initial commissioning The initial commissioning must only be carried out by specially trained personnel (training by RMG) or RMG service personnel. Note An acceptance test certificate must be created during the commissioning. This, the operating manual and the EU Declaration of Conformity must be stored so that they are always readily available.

  • Page 13: Dangers During Maintenance And Repair

    The descriptions in the operating manual must be observed. In general, it is recommended that the replacement should only be carried out by RMG Service. A leak test must be carried out after work on pressurized components.
  • Page 14 1 Introduction Maintenance personnel Work on the device must only be carried out by qualified personnel who can carry out the respective tasks on the basis of their technical training, experience and familiarity with the applicable standards and requirements. These qualified personnel are familiar with the applicable statu- tory regulations for accident prevention and can inde- pendently recognize and avoid potential dangers.

  • Page 15: Qualification Of Personnel

    Risk assessment and minimization 1.2.5. According to assessment by qualified employees of RMG, the TME400 is subject to risks during its use. Risks can arise, for example, due to high pressures and occa- sionally due to pressures that are too low. Work outside of the permissible tempera- ture range can also lead to dangers.
  • Page 16 1 Introduction Non-destructive testing was also carried out: X-ray and ultrasonic inspection of the meter housing for defective points in material, surface crack testing with mag- netic powder and a color penetration process Strength tests for components were conducted at 1.5 times the nominal pressure for the pressure testing;...

  • Page 37: Measuring Ranges

    1 Introduction Measuring ranges 1.4.2.8. Type TME400 turbine meters have measuring ranges of at least 1:20 at atmospheric pressure (see chapter 1.4.2.9 Measuring accuracy). At a higher pressure, the meas- uring range can be expanded to 1:50. The measuring ranges are between 2.5 and 25,000 m /h (operating conditions), depending on meter size.

  • Page 38: Measuring Accuracy

    1 Introduction According to DIN30690-1, the maximum operating pressure for non-flammable gases may not exceed 16 bar; for flammable gases, EN746-2 defines a maximum pressure of 5 bar for DN25 and 2 bar for DN40. Usually these pressure restrictions are speci- fied on a plate on the pipe fittings.
