Density input wiring:
When using a live densitometer input with frequency signal, the signal can be brought into the Smart Flow
Computer in its raw form. The Smart Flow Computer accepts a sine wave or square with or without DC
offset. Example for density wiring can be seen in the wiring diagram. Use the arrow keys to get to

and press ENTER . Find two drawings, one with barrier and the other without.
Barriers are used for area classification. Notice that the RTD wiring is also drawn to show how to hook the
density RTD signal.
Note: When wiring the density input polarity is of significance and
reverse polarity could result in some damage or power loss. The
density signal is on connector P4, the third and fourth pin down
from the top. The third pin down is density plus, the fourth down is
density minus. When Density input is 4-20mA it should be
connected as a regular 4-20mA signal to the analog input and not
the density frequency input.
