Digital Output lets you configure the functional operation of the associated
output. The following operations are supported:
• Reverse Pulse – Generates pulses during reverse flow conditions.
• Forward Pulse – Generates pulses during forward flow conditions.
• Frequency Output – Generates pulses correlated to the absolute value of
the flow rate.
• Preset Output – Provides indication when preset batch amount has been
realized.
• Flow Set Point – Provides indication when flow rate exceeds thresholds
defined by flow set points.
• 24V DC Supply – Provides constant 24 volts on output (forces output type
to normally open).
• Error Alarm – Provides indication when meter has error condition. Error
conditions include, empty pipe error, full scale flow error, and detector
error.
• Flow Direction – Provides indication on current flow direction
(Inactive = Reverse or No Flow, Active = Forward).
• Empty Pipe Alarm – Provides indication when pipe is empty.
• ADE – Provides meter information in digital format. See "ADE Interface" on
page 52.

Flow Simulation
[Off]
S
Flow Simulation provides output simulation based on a percentage of the full scale flow. Simulation
will not accumulate the totalizers. The range of simulation includes –100% to 100% of the full scale
flow.
The Flow Simulation Parameter lets you set the range of simulation in 10% increments.
To change the Flow Simulation, follow these steps from the
Inputs/Outputs
menu:
1. Select
Flow Simulation
to view the
Flow Simulation
display.
2. Click
[+]
to increment the percentage by 10, or click
[–]
to decrement the percentage by 10.
3. Press
[E]
to save the displayed setting and return to the
Inputs/Outputs
menu.
