1 INTRODUCTION
For many years, SCADA system integrators have struggled to eliminate the totalization errors
that resulted from using pulse-output flow meters.
With pulse-technology, the most common problem is the inevitable discrepancies between the
meter readings displayed within the SCADA system and the readings displayed on the physical
meters themselves.
Today, SCADAmetrics has eliminated these errors with the introduction of the EtherMeter™ – the
telemetry appliance that can ensure absolute agreement between the SCADA system and its
connected meters… also known as revenue-grade accuracy.
The effectiveness of the EtherMeter is based upon an embrace of the latest AMR (Automatic
Meter Reading) technology. Driven by the powerful SCADAmeter™ protocol conversion engine,
it works by translating totalization and flow rate signals from modern, encoder-based flow meters
into industrial protocols that SCADA systems can understand, such as MODBUS, Allen Bradley
DF1, and EtherNet/IP.
And for flow-metering applications where encoder technology is not readily available (e.g.
chemical, natural gas, petroleum, steam, etc.), the EtherMeter can process most 2-wire pulse
signals, as well.
The purpose of this manual is to provide the system integrator with the know-how to set up,
install, and maintain the EtherMeter – the new vital component built for today’s modern SCADA
systems.

G. Safety Considerations And Warnings
The following warnings and guidelines should be followed in order to ensure safe operation of your EtherMeter:
• Do not attempt to service the internal circuitry of the EtherMeter. This device contains no user-
serviceable parts or adjustments.
• Carefully inspect the work area in which the EtherMeter will be located to ensure against hazards such as
damp floors, ungrounded power extension cords, and missing ground connections.
• Before operating the EtherMeter, ensure that the external power source is an NRTL-listed power supply
that is rated for a DC voltage between 9 and 36 VDC and rated for a minimum current of 275 mA. If you
are not sure of the type of power source, contact your vendor or SCADAmetrics.
• The secondary output circuits of the EtherMeter are SELV (Safety Extra Low Voltage). Ensure that the
secondary output circuits are not connected with hazardous energy levels.
• The EtherMeter has been evaluated and NRTL-recognized for use in a Pollution Degree 2 environment.
• The EtherMeter must be examined for compliance with the applicable safety standard after installation
into the final enclosure.
• The EtherMeter must be installed in accordance with all applicable local electrical codes.
• If the EtherMeter is exposed to moisture or condensation, disconnect it from the power source
immediately and obtain service assistance.
• If the EtherMeter exhibits unexpected behavior, such as smoking or becoming extremely hot, disconnect
it from power sources immediately and then obtain service assistance.
• Ensure that the EtherMeter’s cover is secure on completion of installation to reduce safety hazards.
H. Environmental Considerations and Cautions
The following is a list of environmental considerations that will help ensure safe and efficient operation of your
EtherMeter:
• Do not position the EtherMeter near high-powered radio transmitters or electrical equipment, such as
electrical motors or air conditioners. Interference from electrical equipment can cause intermittent
failures.
• Do not install the EtherMeter in areas where condensation, water, or other liquids may be present. These
may cause safety hazards and equipment failure.
I. FCC Class A Notice

POWER AND GROUNDING NOTES:
1. The EtherMeter requires a 9-36 VDC Power Supply (2.50 W Max). It is recommended
that the common of the DC power supply be bonded to earth ground.
2. All connected communication equipment must utilize the same ground reference. To
achieve this, a low-impedance ground bus wire should be tied to the DC common of each
connected communication device.

5 METER COMPATIBILITY
Encoder-Based Flow Meters
The EtherMeter features two flow meter ports, each of which is capable of reading most 3-wire
“absolute encoder” registers. In general, encoder registers can be classified as one of the
following:
•Sensus Protocol
•Neptune Protocol
•K-Frame Protocol
To maximize ease-of-use, the EtherMeter automatically recognizes the connected meters’
communication protocols, so it’s truly “plug and play”.
Compatible encoder-based flow meters include those produced by ABB, Actaris, Badger, Elster-
AMCO, Kent, Hersey, Invensys, Itron, Master-Meter, Metron-Farnier, Neptune, Rockwell,
Schlumberger, Sensus, Siemens, Sitrans, and perhaps others.
The complete Meter Compatibility Matrix document is available for download from the Support
section of scadametrics.com. This document details the various meter brands and models that
are compatible with the EtherMeter, along with specific configuration details for each meter.
If there is a Sensus-, Neptune-, or K-Frame-protocol encoder meter register that is not listed
within the document as compatible based upon testing, and you would like to see it listed as
such, then please contact SCADAmetrics. Note that in such cases, we may request a register for
testing and verification.
Pulse-Based Flow Meters
The EtherMeter’s flow meter ports are compatible with most pulse-based flow meters.
Compatible signals include dry-contact, solid-state contact, and open-collector. Flow meters that
produce active voltage or current pulses are NOT compatible.
10
6 SENSUS PROTOCOL METER SUPPORT
The Sensus Protocol, as implemented within the Sensus ICE™ and OMNI T2 registers, the
Badger ADE register, and numerous compatibles, is fully supported by the EtherMeter.
Important Notes:
(1) Most Sensus-compatible registers do not provide the maximum resolution (digits) by default,
and therefore may require factory pre-programming. See the Meter Compatibility Matrix for
configuration details.
(2) Wire color-coding for Sensus-compatibles varies among meter brands. See the Meter
Compatibility Matrix for details.

PARALLEL ETHERMETER HOOKUP FOR SENSUS-COMPATIBLE REGISTERS:
Two EtherMeters may be connected in parallel to a single meter register with the aid of the
Radio-Read Filter (SCADAMETRICS P/N RRF-50).
The following diagram demonstrates the hookup of a Sensus-compatible encoder register to two
EtherMeters. In this example, terminals 14, 15, and 16 are used on both EtherMeters (Meter
Channel 1). However, either channel may be used on each EtherMeter. Check the Meter
Compatibility Matrix on scadametrics.com, in advance, to ensure compatibility.
In the place of the second (rightmost) EtherMeter in the diagram, a three-wire AMR device may
be installed. Examples include the Sensus MXU, Neptune R900, Itron ERT, and many others.
It is important to note that the Radio-Read Filter derives all necessary power from the first
(leftmost) EtherMeter in the diagram. No external power supply is required.

8 K-FRAME PROTOCOL METER SUPPORT
K-Frame Protocol support applies to certain meters manufactured by Elster-AMCO, Kent, and
ABB. Compatible registers include the InVISION (Elster-AMCO), ScanCoder (Elster-AMCO,
ABB, Kent), and the AquaMaster mag-meter (ABB).
Important Notes:
(1) The instructions in this chapter do not apply to Sensus-protocol registers that are
manufactured by Elster-AMCO (See Ch. 6, Sensus Protocol Meter Support).
(2) See the Meter Compatibility Matrix for meter register configuration details.
(3) Wire color-coding for K-Frame-compatibles differs from that used in Sensus-compatibles and
Neptune compatibles.
