Velocity is determined by measuring the time difference between the measurement in the forward and reverse direction. Flow totalization can then be calculated from the measured flow velocity using water temperature and pipe diameter. The meter is all electronic with totally potted circuitry, display and battery. There are no moving parts to wear or replace and meter and registration are sealed, non-removable and protected from tampering. SIZE, CAPACITY, AND LENGTH Along with the operating and physical characteristics, the nominal size, capacity ratings, related pressure loss limits, and length of the meters must conform to American Water Works Standard C-700 as most recently revised. Meters supplied under this specification shall operate without leakage or damage at a working pressure of 175 psi. METERING TUBE The housing shall be lead-free and shall be designed so that at a working pressure of 175 psi, any distortion will not affect the accuracy of the meter. Metering tube shall not be repaired in any manner. The flow direction and meter size shall also be cast in the meter tube and the inlet and outlet shall have a common axis. METERING INSERT The ultrasonic metering insert shall be self-contained within the meter flow tube, seated, and not removable. The insert shall be secured to the main case, providing a method of minimizing turbulence and cleaning the reflectors, so that the accuracy of the meter will not be affected by any distortions of the case when operating at a pressure of 175 psi. The metering insert shall be made of thermoplastic polymer and stainless steel and the ultrasonic transducers shall be wetted components that extend through the meter tube and shall have a surface of stainless steel. ELECTRONIC METER AND REGISTRATION The electronic circuit shall be micro-processor based and include a non-replaceable battery, and non-volatile memory capable of storing all programmable data and accumulated data. The circuit shall control the ultrasonic transducers. No field programming or calibration shall be necessary. The entire meter circuit and related components shall be fully potted and sealed from water intrusion. No components shall require service or replacement over the life of the meter. For reliability, the use of inductive coil technology shall not be permitted with an electronic residential meter. REGISTRATION/DISPLAY 8.1 The registration lid shall have the name or logo of the manufacturer permanently molded and the serial number shall be imprinted for identification. The lid shall overlap to protect the lens and be made of engineered polymer. 8.2 The registration shall be encased in an integral non-corrosive polymer housing, with the electronics, display, and battery completely potted within. It must be permanently epoxy sealed to provide moisture resistance to flooded pit or submerged conditions. The permanent seal between the lens and non-corrosive polymer housing shall utilize an adhesive seal. 8.3 The Register shall be an integral part of the meter assembly and must be available factory wired to an inline connector that can be used to connect to an endpoint. 8.4 The registration shall consist of an electronic display combined with electronic circuitry to provide a high-resolution absolute encoder output. This electronic registration assembly shall transmit a signal through properly shielded (grounded) transmission wire for AMR/AMI connectivity. 8.4.1 The High-Resolution industry standard ASCII encoder protocol shall be capable of sending a 9-digit encoder output to the endpoint as well as extended status messages. Resolution being sent to the reading software is based on the output of the endpoint. 8.5 The display shall be a straight reading, permanently sealed electronic LCD with digits 0.28 inches high. The display will contain 9 digits plus a decimal point and display consumption, unit of measure, rate of flow and alarm information. The digital display shall provide a totalized consumption resolution to 0.01 gallons, 0.001 cubic feet, or 0.0001 cubic meters for 5/8” through 1” meters and 0.1 gallons, 0.01 cubic feet, or 0.001 cubic meters for 1-1/2” and 2” meters. 8.6 The size, model, and direction of flow through the meters shall be permanently visible on the topside of all meter displays. The units of registration, U.S. gallons, cubic feet, or meters cubed, shall also be designated on the LCD display. The enhanced resolution of the totalized flow display can be utilized as a flow indicator for leak detection. REGISTRATION ACCURACY The meter shall register not less than 98.5% and not more than 101.5% of the water passed through the meter. At the minimum test flow rate, the meter shall register not less than 97.0% and not more than 103.0% of the water passed through the meter. REJECTED MATERIALS/METERS The Manufacturer shall, at his own expense, replace or satisfactorily adjust or repair all units rejected for failure to comply with these specifications. OTHER TERMS The City of Mankato has the right to accept or to reject all bids. If unable to supply pricing for all sizes requested, please note not applicable if you do not have a source for those sizes All bids must be inclusive with shipping and handling charges incorporated in bid pricing; no additional fees allowed at invoicing. Addendum A: Meters will be pre-assembled, with standard thermoplastic polymer connections, gaskets, and meter couplings. The meters shall be all electronic and ultrasonic; the meter should totally have factory potted register, circuitry, display and battery. There are no moving parts to wear or replace and meter and registration are sealed, non-removable and protected from tampering. No field programming or calibration shall be necessary, and the entire meter circuit and related components shall be sealed from water intrusion and resistant to submerged conditions. High resolution encoder. The meter shall be warranted for AWWA accuracy. Meters of 2” to 6” will need to have a nipple and stainless-steel ball valve test port put on if possible.
