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 E-Series Ultrasonic 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 E-Series Ultrasonic meter is available with a 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
