The parameter "Simulate - Value Measurand" (
Page 89) allows you to specify a simulation value
in order to test assigned parameters in the device and downstream function blocks. The process
variable (volume or mass flow) to be simulated is selected by means of the "Simulation - Measurand"
parameter (
The parameter "Low Flow Cut Off - On Value" (
Page 83) allows you to define a limit value for
low flow cut off. If the measured flow value is below this limit value then the output value of 0 is
output.
In addition, the parameter "Sys. - Positive Zero Return" (
Page 82) allows you to switch the
measured value to "Zero Flow". This is necessary when a piping system is being cleaned, for
example.
The "Flow" Transducer Block makes the process variables volume and mass flow available to the
downstream function blocks. Depending on these two process variables, the "Totalizer" Transducer
Block derives the integrated measured variables Totalizer 1 to 3 which are then also made available
as a process variable at the output for further processing. In addition, the totalizers are also
configured in this Block; for example all totalizers can be reset simultaneously by means of the
"Tot. - Reset All" parameter (
The "Diagnosis" Transducer Block comprises all the parameters and functions necessary for the
diagnosis and maintenance of the device. For example, the "Diag. - Act.Sys.Condition" parameter
displays the current system condition or, if an error occurs, provides a detailed reason for the error
(
If the measuring device is equipped with a local display, various display parameters can be
configured by means of the "Display" Transducer Block, e.g. display language, contrast etc.
(
The "Diagnosis" and "Display" Transducer Blocks do not have any output variables, i.e. they only
affect the measuring device itself.
The primary functions and parameters of the Transducer Blocks are listed below. You will find an
overview of all the available Hauser-specific parameters starting on

Important functions and parameters
of the Transducer Blocks
3.2.1
Block output values
The Transducer Blocks make the following output variables (process variables) available:
• "Flow" Transducer Block:
– Calculated mass flow
– Volume flow
• "Totalizer" Transducer Block
– Totalizer 1
– Totalizer 2
– Totalizer 3
• The "Diagnosis" and "Display" Transducer Blocks do not have any output variables.
