4.1 Operating limits
The values specified on the rating plate and the calibration certificate apply. The permissible operating
limits of individual values influence each other so that every application is checked individually by the
manufacturer when selecting the flowmeter.
If no operating data are provided by the orderer, standardized substitute operating data are used.

Strong pressure pulsations in the system can
reduce the service life of the flowmeter.
4.3 Maximum values
The following table shows the respective maximum values that, however, may not occur simultan-
eously. In addition, the operating limits of the corresponding completion, of the sealing material and of
the pick up are to be observed.
