Flow Simulation
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…100% of the full scale flow.
The Flow Simulation Parameter lets you set the range of simulation in increments of 50 (OFF, 0, 50, 100,
-50, -100). The factory default is OFF.
Digital Input
S
• Digital input lets you reset totalizers or interrupt flow measurement.
• Input switching is provided by applying an external voltage of 3…35V DC.
• Use a “normally open” contact for operating.

Pulse/Unit
S
This parameter lets you set how many pulses per unit of measure will be
transmitted to remote applications. For example, assuming the unit of measure
is gallons:
• Setting the Pulses/Unit to 1 (standard setting) will transmit 1 pulse
every gallon
• Setting the Pulses/Unit to 0.01 will transmit 1 pulse every 100 gallons
You must configure pulses/unit if the function of the selected output is to be
forward or reverse .
This parameter must be considered with the Pulse Width and Full Scale Flow
parameters. The maximum pulse frequency is 100 Hz. The frequency is correlated
with the flow rate. Violation of output frequency limits will generate a PULSE_
OVERLOAD_WARNING.
Width
S
This parameter establishes the ON duration of the transmitted pulse. The
configurable range is 0…500 ms. The factory default is 0 ms.
• Non-zero pulse width configuration – the OFF duration of the transmitted
pulse is dependent on flow rate. The OFF duration is to be at least the
configured ON duration. At full scale flow, the ON duration equals the Off
duration. The maximum configurable output frequency is limited to 100 Hz.
• The duty cycle of the transmitted pulse is at 50% of the output frequencies
greater than 1 Hz.
This parameter must be considered with the Pulses/Unit and Full Scale Flow
parameters. The maximum pulse frequency is 100 Hz. The frequency is correlated
with the flow rate. Violation of output frequency limits will generate a PULSE_
OVERLOAD_WARNING.
Power
Line Frequency
S
This parameter provides measuring immunity to industrial noise from a power
supply feed.
This parameter should be set to your nominal line frequency, typically 50 Hz.
