OUTPUTS
Encoder Output
Programmed to the industry standard ASCII encoder protocol, E-Series Ultrasonic meters have the ability to transmit meter
status indicators to ORION Cellular, Fixed Network (SE) and Migratable (ME) endpoints as part of the extended
encoder/meter reading message. The details can also be read through an IR interface.
Endpoint Reading Resolution
The standard electronic encoder output resolution of the meter is 9 digits. Though the meter output is 9-digit resolution,
the reading resolution sent to the reading software is dependent on the endpoint that the meter is connected to. Readings
reported from the endpoints are the left-most significant digits of the encoder reading.
Endpoint Technology Reading Resolution Reported to Reading Software
ORION Cellular 9-digit reading, plus the extended message capability
ORION Migratable (ME)/Fixed Network (SE) 8-digit reading, plus the extended message capability
ORION Classic (CE) 7-digit reading
GALAXY 6-digit reading
Wire Connections
The meter is available with an in-line connector for easy connection and installation to AMR/AMI endpoints. It is also available
with a flying lead for field splice connection. The in-line connector is recommended for pit applications.
Dual Output
The E-Series Ultrasonic meter is also available with dual outputs. The following dual output options are available:
• Encoder and encoder • Encoder and 4-20 mA
• Encoder and scaled/unscaled • Scaled/unscaled and 4-20 mA
Scaled Output
• Scaled output is a switch closure output defined as: red wire = positive, black wire = negative.
• Scaled output from the register has a default resolution 1/10th of the register test circle (resolution may vary in
some cases).
• The nominal pulse output width is programmable from 30…100 msec.
• This pulse output is compatible with most totalizers and batch controllers.
Unscaled Output
• Unscaled output is a switch closure output defined as: green wire = positive, black wire = negative
• This pulse output is compatible with most totalizers and batch controllers.
Analog Output
• The flow rate measurement is converted to a standard 4-20 mA control signal.
• This signal is proportional to the flow of fluid passing through the flow meter.
• The 4-20 mA output is isolated when paired with scaled/unscaled output.
• Power for the device can be obtained from a 9…50V DC control loop.
