http://www.wbdg.org/ccb/ccb.php

2.2.3 All new and replacement meter installations, shall be provided with voltage and current safety disconnect devices or equivalent, so that the meter assembly can be worked on safely over the life of the meter installation and not require utility outages for servicing.

2.2.4 The Contractor shall include all disconnects, mounting hardware, enclosures, wiring and conduit, and safety equipment as required and appropriate to complete the task and provide fully functioning meters and a meter data management system. The Contractor shall provide all wiring equipment, and conduit required to connect the new meter to a ”RJ 45” connector VLAN drop that will allow transmission of the metering data to the AMRS platform. Electric Meter shall not be mounted on or attached to outdoor mounted transformers.

2.2.5 All current, power, and voltage circuit termination points for wires entering the meter or enclosure must be clearly marked, to avoid installation error and simplify future identification of wires for maintenance purposes. These identifying markings shall be reflected on the As-Built drawings.

2.2.6 Outdoor meters should be installed in a weatherproof enclosure, which can be locked with a padlock unless the meter itself is designed for outdoor use.

2.2.7 Meter installation shall comply with UFGS section 26 27 13.10 30

2.3 Gas Meter: Contractor shall install an “Elster American Standard” meter with “KY” or

“KYZ” pulse output or approved equal.

2.3.1 Meter shall be a positive displacement type.

2.3.2 Meter shall have an odometer style display.

2.3.3 The contractor shall use one of two options to connect the meter pulse output to the

AMRS platform.

2.3.3.1 Using a “KY” or “KYZ” pulse interface, the contractor shall connect to the advanced electric meter’s “KY” or “KYZ” input terminals. The contractor shall be responsible for ensuring that the pulse output interface is compatible with the existing advanced electric meter.

2.3.3.2 Using a “KY” or “KYZ” pulse interface, the contractor shall connect to a Pulse

Accumulator and “MODBUS/TCP” Converter. The contractor shall provide the accumulator and converter equipment. Connect the resulting output to a “RJ 45” connector VLAN drop. The

Contractor shall provide all wiring, equipment and conduit required to connect the new meter to a

“RJ 45” connector VLAN drop that will allow transmission of the metering data to the AMRS platform.

2.3.4 The meter should comply with the most current AMRS Meter Specifications as listed in

2.3.5 Meter installation shall comply with UFGS section 33 51 13.00 30

2.4 Water Meter: Contractor shall install a "McCrometer” water meter with pulse output or approved equal.

2.4.1 The water meter shall meet or exceed the flow characteristics of the following chart with special emphasis on the “Typical Low Flow (95% Minimum).

6” 5 GPM 15 to 1300 GPM 910 GPM 1430 GPM

2.4.2 The contractor shall use one of two options to connect the meter pulse output to the

AMRS platform.

2.4.2.1 Using a “KY” or “KYZ” pulse interface, the contractor shall connect to the advanced electric meter’s “KY” or “KYZ” input terminals. The contractor shall be responsible for ensuring that the pulse output interface is compatible with the existing advanced electric meter.

2.4.2.2 Using a KY” or “KYZ” pulse interface, the contractor shall connect to a Pulse

Accumulator and “MODBUS/TCP” Converter. The contractor shall provide the accumulator and converter equipment. Connect the resulting output to a “RJ 45” connector VLAN drop. The

Contractor shall provide all wiring, equipment and conduit required to connect the new meter to a

“RJ 45” connector VLAN drop that will allow transmission of the metering data to the AMRS platform.

2.4.3 The meter should comply with the most current AMRS Meter Specifications as listed in

2.4.4 Meter installation shall comply with UFGS section 33 12 33.00 30

3. Contractor shall verify exact equipment and coordinate connection details with Energy

Management Control System (EMCS) personnel at Nellis AFB (99 CES personnel in Bldg 812).

4. Contractor shall verify the information outputted from meters is properly routed to the base-wide AMRS platform, located on the server in building 822, and is viewable via login to the

“Wonderware” software.

5. All metering hardware and software equipment shall be provided to allow full integration into the AMRS platform and to allow the platform to manage, store, manipulate, trend, and graphically present the data.

6. The meters are required to be tested, adjusted and commissioned in accordance with manufacturer’s recommendations and also in accordance with the UFGS.

7. Interface with Existing Data Transmission Equipment: Interface all data transmission equipment installed by other sub-contractors, in accordance with directives and requirements of the local Communication Squadron, specifications, drawings and manufacturers’ published documentation. Comply with all requirements of the Communication Squadron to interface with the existing communication system.

8. Standalone meters may be used on facilities with less than 10 tons of installed cooling

AND having no access to a communication rack in the facility. Total tonnage is calculated by summing all air condition units installed on the facility.
