200631v1 <br />f) Electronic Register. The solid state meter electronic enclosure shall be constructed of a durable <br />engineered composite designed to last the life of the meter. The meter shall provide a fully potted wire <br />connection for use with AMR/AMI devices. <br />g) Environmental. The solid state meter must feature fully potted electronics and battery as well <br />as carry an IP68 rating for submersion in flooded meter pits. <br />h) Registration. The register shall provide at least a 8-digit visual registration at the meter. <br /> The register shall provide an 8-digit meter reading for transmission through the RF <br />AMR/AMI Meter Interface Unit (MIU). <br /> The register shall employ a visual LCD leak detection indicator as well as provide remote <br />leak detection through an ASCII format to the RF AMR/AMI MIU. <br /> The register shall provide reverse flow detection, communicated as ASCII format data to the <br />RF AMR/AMI MIU. <br /> The register shall provide an indication of days of zero consumption, <br />communicated as ASCII format data to the RF AMR/AMI MIU. <br /> The register should accumulate and register consumption without connecting to a <br />receptacle or RF AMR/AMI MIU. The register shall display flow rate information (interleaved with <br />the current meter reading). <br /> The register shall subtract reverse flow from the total registration. <br />i) Performance. Meter manufacturer’s solid state meters shall exceed AWWA C715 accuracy <br />standards and warrant their published accuracy levels for the life of their meters. Each meter shipment must be <br />accompanied by factory test data showing the accuracy of the meter as tested at their factory. <br />j) Manufacturer. Manufacturers shall be a member of AWWA. <br /> <br />4) Remote Encoder-Based Meter Information System. Provide an encoder-based remote <br />metering system capable of providing digitally encoded meter information as specified herein. <br />a) These specifications require a self-contained encoder register metering system designed to <br />obtain remote simultaneous water meter registration directly from the register odometer. The metering <br />information shall be obtained through an RF Unit using a compatible data capture system. <br />b) The system shall be configured as follows: <br /> Encoder meter register: Direct mounting, encoded odometer wheels and digital data <br />stream. <br /> Remotely mounted RF Unit (where required) to provide a communication link for the <br />transmission of information from the register to the reader. <br />c) Equipment shall be configured to: <br /> Capture information and display it vis ually to confirm correct system installation <br />wiring. <br /> Be pre-programmed with route information and capable of storing collected data in <br />solid-state memory. This device shall also electronically transfer the data for use by the utility billing <br />computer. <br />d) Encoder registers shall be AMR/AMI capable, and manufactured by the same manufacturer. <br />A guarantee of encoder compatibility with the AMR /AMI system shall be provided upon request. <br />e) Registration: The register shall provide a eight (8) digit visual registration at the meter. The <br />unit shall, in digital format, simultaneously encode the eight (8) most significant digits of the meter <br />reading for transmission through the AMR /AMI device. The register shall employ a leak detection <br />indicator on the dial face. <br />f) Meter Reading Information: The encoder register shall provide to the reading <br />equipment up to eight (8 ) digits of meter reading. An identification number of up to ten (10) digits <br />shall be provided with each reading. The absolute encoder re gister must have the capability to <br />provide additional custom information to the reader. <br />g) Remote RF Unit, where required for reader capability: A remote receptacle shall be <br />provided for attachment by wall mounting. The materials employed shall be corrosion r esistant, <br />resistant to ultraviolet degradation, and unaffected by rain or condensation. The RF Unit shall be <br />powered by a battery that has a minimum life of 20 years. The connecting cable shall be of the 22 - <br />gage, four- (4) wire conductor type in an abrasio n- and moisture-resistant sheath. Each conductor
