4.4 Substitute operating data
The following table shows standardized values for the flow rate, temperature and viscosity. These val-
ues can be used at the same time as maximum values without impairing the service life of the flow-
meter. In addition, the operating limits of the corresponding completion, of the sealing material of the
pick up and of the temperature sensor are to be observed.
