3.6.2 Transmitter Parameters (Config fld dev var)
① Click on "Setup (S)" at the top-level menu of the screen, select "Config fld dev var" drop-down menu,
and click again.
② A message box like the one shown in Fig. 25 appears. Transmitter parameters (flowrate, density, and
temperature related parameters) are set up at this window.
③ At the Flow menu, you can set up mass flowrate unit, volume flowrate unit, flow direction, flow
damping, and flow cutoff.
In the ST9801 and EV9201, there is no "Volume flow unit" menu item.
Flow direction is either "Forward" of "Reverse." In the "Forward" , the flow direction indicated by the
arrow on the flowmeter body is taken as "Forward" , whereas in the "Reverse" , the flow direction
opposite to the arrow is taken as "Forward" .
"Flow cutoff" reads in percent with respect to the max. permissible flowrate and functions both in
forward and reverse flow. Default setting is "0.3%" .
④ At the Density menu, you can set up density unit, density damping, slug flow identification, and density
correction.
In slug flow identification, any flow in which the obtained density measurement exceeds preselected
"Slug low limit" or "Slug high limit" is interpreted as a gas-mixed flow or slug flow, and the obtained
flowmeter results and their outputs are forcibly reduced to "0." When settings are such that "Slug low
limit"=0 and "Slug high limit"=10, the slug flow identifying function is inactivated. However, within
the period preset at "Slug duration" , the transmitter ignores the status of a slug flow and continues
usual measurement.
In density correction, density and volume flow readings are reduced to the values corrected at the
reference temperature if "Compensation" is "ON" (conversion calculated on the basis of "Standard
temp" and "Expansion Coef").
In the EV9201, there is no "Density" menu item.
⑤ At "Temp" , you can set up temperature units and temperature damping.
⑥ You are to set up individual items : for items with an arrow mark at right, click on the arrow mark at
right, select the item from the drop-down list ; for other items, Key in appropriate values directly.
