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
• 24 Vdc 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
To change the Function Select, follow these steps from the
Inputs/Outputs
Main Menu
:
1. Select
Digital Output 1
,
2, 3 or 4
and press
[E]
to open the Digital
Output menu.
2. From the
Digital Output menu
choose
Select Function
, and press
[E]
to open the Select Function display.
3. Select the desired function.
4. Press

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.
