1、02-10 25 10 10 - 1 SECTION 25 10 10 ADVANCED UTILITY METERING SYSTEM SPEC WRITER NOTES: 1. Delete between /_/ if not applicable to project. Also delete any other item or paragraph not applicable in the section and renumber the paragraphs. This specification section applies to and shall be included w

2、ith all work to be performed under the 22, 23, 26, 32, and 33 Divisions of the Master Construction Specifications. The Section is general in nature, and should be edited to fit each project. 2. Provide schedule for each flow meter listing flow meter type, fluid type and characteristics, temperature

3、and pressure of fluid, flow range (maximum and minimum flows), maximum pressure loss, minimum meter accuracy, English and metric measurement units. 3. The VA has in place a Corporate-Wide Advanced Utility Metering Database, which allows the VA to automatically query some of its facilities for their

4、energy and water usage. This specification rolls-out Advanced Utility Metering Systems (AUMS) to all of its facilities. Each facility shall include an AUMS, periodically transmitting information in a format compatible with the existing VA Corporate-Wide Advanced Utility Metering Database . 4. This s

5、pecification defines the structure for the roll-out of the AUMSs: each VISN or VAMC shall be provided (by this section, if not already in-place) a Site Data Aggregation Device (a PC workstation or server) ; communications between this Site Data Aggregation Device and the VAs Corporate-Wide Advanced

6、Utility Metering Database shall be via periodic TCP/IP communications; communications between the Site Wide Aggregation Device and the facilitys meters shall be via Ethernet cabling (separate from the IT systems and the HVAC control systems cabling), and wireless; and meters of the facilitys energy

7、flows and water flows. 5. Communications (especially TCP/IP) shall comply with NIST-recommended security protocols. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-02-10 25 10 10 - 2 6. Communications between meters and the Site Data Aggregation Devi

8、ce shall allow for real-time and high-sampling frequency automatic monitoring of energy flows throughout and within each facility as well as less-frequent interval or “billing” metering. The AUMS shall include capacity for future automatic control: dispatch of loads depending on thresholds being rea

9、ched, alarm notices auto-sent under various conditions, and the like. The AUMS shall include various levels of operator interface and access, and shall allow for customizable viewports as required by the User. 7. This specification includes meters and communications systems which may not be relevant

10、 to the individual project. The specifying engineer shall survey the site and examine physical conditions and constraints relative the facility being designed. The specifying engineer shall coordinate the metering and communications scope with the facility engineer and the Resident Engineer. The spe

11、cifying engineer shall only then edit this specification to include only those features relevant to and required by the AUMS. 8. Separate cabling or radio transmission (RF) from the meters to the Site Data Aggregation Device is required. The communications transmission shall not be run on the facili

12、tys IT network. If the meters are existing and part of the facilitys direct digital control system, and if those existing meters are sufficient to this Sections mission, the information may then be transmitted over the facilitys direct digital control system network to the facilitys ECC, and from th

13、ere to the AUMS. 9. Show on drawings all communications cabling routing, meter and trim installation details and locations, as well as describing methods and means limitations for the implementation of the AUMS. 10. The specifying engineer shall have complete knowledge of the space and cable pathway

14、s (i.e. equipment rooms, TCs, conduits, wireways, etc.) of the Facility. The specifying engineer shall at a minimum design and install Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-02-10 25 10 10 - 3 the System using the Pathway Design Handbook H-0

15、88C3, TIA/EIA Telecommunications Building Wiring Standards, and VAs Facility Chief of Information Technologies(IT) instructions, as approved in writing by the VA. 11. Design a new system conforming to current and accepted digital industrial/commercial cable and RF distribution standards. The distrib

16、ution cable installation shall be fully coordinated with the VA prior to the start of installation. 12. Specify cable in this system (i.e. backbone, outside plant, inside plant, and station cabling) to conform to this Section and to accepted industry and OEM standards with regards to size, color cod

17、e, and insulation. The pair twists of any pair shall not be exactly the same as any other pair within any unit or sub-unit of cables that are bundled in twenty-five (25) pairs or less. 13. The System cables shall be protected conduit. The specifying engineer shall include Section 26 05 33 in the spe

18、cifications for the work. Some areas of this Facility may be considered “plenum”. If any of wire and cable used in support of the installation in those areas is not in conduit (this guidance does not grant relief from the protection): then the cabling must comply with national and relevant codes per

19、taining to plenum environments. Review the VAs cable and wire requirements with the VA prior to installation to confirm the type of environment present at each location. 14. Design outside- and inside-plant cables that furnish the number of cable pairs required in accordance with the System requirem

20、ents described herein. Fully coordinate and obtain approval of the design with the original equipment manufacturer and the VA prior to installation. 15. Addition of advanced meters shall in no way affect any existing utility meter or its components. This meter shall be used as supplemental informati

21、on. Know that meters installed adjacent other utility meters will not read exactly the Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-02-10 25 10 10 - 4 same. This difference is due to the different turn-down ratios, calibrations to different CTs, a

22、nd also due to differing accuracies of the meters. 16. Existing meters already in place may serve the mission of this Section, provided that they comply with the communications and accuracy requirements of this Section. Confirm this re-use with the VAs Facility Engineer and REO. 17. Unless the const

23、ruction is on a greenfield, most of the utilities metered by this Section are fundamental to the operation of the facility. Choose insertion-type meters and use hot-taps into active piping systems and other means to allow for meter insertion into the utility distribution systems without forcing outa

24、ges of those systems. 18. Meter maintenance is an important concern for the VA: where feasible, specify meters with no moving parts, so minimizing maintenance of mechanical components over the life of the meter. PART 1 - ENERAL 1.1 DESCRIPTION A. This Section includes the following for the advanced

25、metering of the systems of the facility. The metered systems include the electrical power, natural gas distribution, fuel gas and fuel oil, steam, steam condensate, chilled water, heating water, domestic water, recovered water and makeup water systems. The metering systems in each facility are part

26、of a Corporate-Wide utility metering system, rendering the VA accurate and automated metering of its facilities energy and water flows. Metering systems are comprised of: 1. PC-based workstation(s) or server(s) and software. 2. Communication network and interface modules for /RS-232, RS-485, Modbus

27、TCP/IP, IEEE 802.3/ data transmission protocols. 3. Electric meters. 4. Volumetric flowmeters, temperature sensors and pressure transducers. 5. Mass flowmeters.
