5. Functions
This chapter describes each function of the product. The overview of each function is as follows.
NOTE
F Fieldbus items found in the following menu path tables indicate a case where
OUNDATION
FieldMate, Yokogawa Electric's adjusting and setting tool for field device/environmental device, is
used.
NOTE
For various setting changes, there is a mode which allows each parameter to be written.
For details, refer to "A1.2 Setting and Change of Basic Parameters".
If the parameter cannot be rewritten, check for write mode columns in parameter lists in Chapter
6.
Basic settings
„ „
This product can measure process values of the flow velocity, volumetric flow rate, mass flow
rate, calorie, and flow noise at the same time. A damping time constant can also be specified for
each process value.
For details about how to check measured results and the setting procedures, refer to Section 5.1.
Totalization function
„ „
Two totalizers are mounted to totalize selected process values. In addition to the totalized value
display function, the product has a totalization counter function to scale totalized values with the
conversion factor and to count a specific flow rate. The product also has the totalization switch
function that compares a specified target value with a totalized value to output the result as the
status output, and the totalization preset function that starts totalization with the value specified in
advance.
For details about the totalization function and setting procedures, refer to Section 5.2.
Limit switch function
„ „
This is the function to transmit 0 and 1 as a parameter by judging whether the selected process
value is above or below the threshold.
For details about each output and the setting procedures, refer to Section 5.3.
Inputting external temperature
„ „
As a temperature value for the temperature correction of the mass flow rate, a temperature value
can be imported from an external device.
For details about inputting external temperature, refer to Section 5.4.
Auxiliary calculation function
„ „
This function is used to calculate the temperature correction for density or the calorie by inputting
the temperature from an external device. The accuracy of mass flow rate measurement is
improved with the temperature correction for density.
For details about the auxiliary calculation function, refer to Section 5.5.
