6.2.5 Units, figures and factors
Numerical values and factors are displayed in a 8 digit format. Numerical values are either
displayed in floating point format (12345678) or are expressed in exponential format (12.345e06).
Exponents are used in following steps: 03 / 06 / 09 or -03 / -06 / -09 etc. The conversion factor of
the totalizer and the pulse output, however, is expressed in whole numbers.

Table 6-4: Basic units
User defined units can be entered in menu "A9 or C6.5 Units". The unit (text) as well as the
conversion factor (number) and offset can be entered here. The conversion factor must always
be entered based on the basic unit.
Totalizer
The basic units for the totalizer are m
Volume flow, norm. volume flow and mass flow can be selected in menu "C4.1 Flow Totalizer".
If counting is to be done in another flow unit, the unit must be changed in menu "C6.5 Units".

Access levels
The vortex flowmeter features a multi-level security concept, which helps to prevent accidental
or unauthorised configuration changes.
To gain a specific access level you need to log into the device by entering a four digit hexadecimal
password associated with that access level (refer to menu "C6.2 Security"). You are able to
change the passwords of "Operator" and "Expert" access levels if that particular level has been
reached.
The "User" access level does not have a specific password – if you enter any password not
assigned to a level, e.g. "0000" (which is an invalid password), you will fall back to "User" access
level.
