ONICON Turbine Flow Meter
Factory Installed Cable
ONICON turbine flow meters are provided with a variety of output signals. Only the red,
green and black wires are required to power the flow meter and operate the display. For
bi-directional applications, the gray and violet wires are also required to indicate flow
direction.

3.3.1.1 ONICON Turbine Flow Meters
ONICON turbine flow meters are provided with a number of different output
configurations. These affect the number of wires contained in the cable attached
to the flow meter. Refer to the diagram below and the laminated tag attached to
the flow meter for specific details.
• Top and bottom turbine signals are only used with the F-1200 and FB-1200
flow meters.
• Directional contacts are only used by FB-1200 flow meters.
• Terminal block positions are provided for additional flow meter signals that
may be available, but are not actually used by the D-100.
