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

Noise levels
KRAL flowmeters operate almost silently.
Heating system
A heating system is not installed at the factory. The customer can optionally fit OME-series KRAL
flowmeters with a trace heating system. The manufacturer recommends heating systems for high-
viscosity liquids that do not flow sufficiently if not heated, because bearing damage and destructive of
the device may otherwise result.
Trace heating system
Contact the manufacturer before installing a trace heating system.
