All materials containing pressure (process connections, flow divider and tubes) are traced back to the
original manufacturer with a material certificate. The PED limits the pressure and temp, which can be found
below.

The given temperature /pressure ranges are calculated and approved without corrosion or erosion. The
customer is fully responsible to select proper materials to withstand his corrosive or erosive conditions. In
case of heavy corrosion and/or erosion the instrument may not withstand the pressure and an incident may
happen with human and/or environmental harm. Yokogawa will not take any liability regarding damage
caused by corrosion / erosion. If corrosion/erosion may happen, the user has to check periodically if the
necessary wall thickness is still in place.

ROTAMASS is produced according the determinations of directive 97/23/EG (Directive for Pressure Equipment
/ PED).The units are classified as pipe according item 3, number 1, 3. letter, a) first dash or according

diagram 6 after appendix II :

Classification as pipe
For Fluid Group 1 and 2 (article 9 chapter (2)); For fluid group 2 with a max. partial
pressure of 1.5bar at T

max.

.

Medium liquid and gas

The basic safety requests (for design, production and testing) for all units according to category I to III are
generally determined for the requests of category III. The units, which are not included by PED, article 3
paragraph 3, are checked by a conformity-valuation–methode according appendix III “module H”.

The complete quality assurance system according PED appendix III module H was
certified by the notified body :
Lloyd’s Register Nederland B.V.; Weena-Zuid 170; NL-3012 NC Rotterdam

ID-No. 0038

Number is printed on name plates (see chapter 3.11).

For the application the following notes have to be noticed :

Permitted maximum operating temperatures:
The pressure relevant temperature limits of the detector are : -200 to 400°C
These limits are reduced by measuring boundary conditions :

General :

-40 to 150°C

Additional reductions for the use of special connections (clamp, pipe screwing ...) have to be noticed ac-
cording the concerning standards.
