4-20mA CONNECTION
The FUSION is equipped with a ground-referenced 4-20 mA
output—the output shares a common ground with the power
supply. The output transmits a continuous current output that is
proportional to liquid flow rate. The output was scaled at the
Dynasonics factory and the scaling information is recorded on the
label located outside of the FUSION enclosure. To ensure that the
instrument or data acquisition system that is receiving the 4-20
mA signal responds properly, the receiving device must be
spanned identically to the FUSION.
IMPORTANT: The RATE PULSE and 4-20mA outputs cannot
be operated simultaneously. Select the desired output type
from the OUTPUT menu. Details of this selection are covered
in the Flow Meter Configuration section of this manual.
