Quality Assurance 1. The equipment to be Kamstrup branded, including the latest version of embedded acoustic leak detection. 2. All materials and equipment supplied under this Section shall be new, of good quality, and in good condition B. Meter Construction 1. All water meters shall use ultrasonic measuring technology with no moving parts. 2. All sensors and electronics shall be designed so that they are fully protected against internal and external penetration of fluid. 3. The meters shall be hermetically and vacuum-sealed to prevent humidity from entering the electronics and avoid condensation between the glass and display. C. Materials: Meters shall be made available in both 40% fiberglass reinforced Polyphenylene sulfide (PPS) or 316L Stainless Steel meter bodies. D. Battery 1. 5/8"x1/2" - 1", the Warranty Period is twenty (20) years (10 full/ 10 prorated) from the date of delivery to Buyer. The battery in 6" and larger meters shall be field replaceable with no need to take the meter out of service. 2. The meter shall provide a low battery warning on the display in accordance with AWWA C715 operating guidelines and be transmitted as an alert to the AMI system. E. Measurement 1. Maximum permissible error shall fall in accordance to AWWA C715-18 operating guidelines +- 1.5% in normal flow range and +- 3% for low flow ranges. 2. Starting flows on 5/8" meters shall start measuring as low as 0.008 GPM. 3. Water meters shall have the ability to measure, log, and transmit the temperature of the water and ambient temperature over the AMR or AMI network. F. Flow Validation: All meters shall have the ability to log a total of historic volumes by flow rate range to conduct a consumption profile for the installation. G. Approvals, Certifications, Standards, and Ratings 1. The meter shall be approved according to Drinking Water Standards in multiple countries and certified to NSF/ANSI 61. 2. The meter shall fully comply with AWWA C715-18 guidelines. 3. The meter shall be IP68 type tested and able to operate fully submerged 4.

Meters up to 2" shall have the capability to monitor and record acoustic noise to enable distribution side leak detection. 2. The acoustic leak detection sensor and electronics shall be integral to the meter, requiring no external hardware or wired connections. 3. The acoustic data shall be captured and communicated regardless of reading method (AMR or AMI). 4. The acoustic functionality may be activated immediately at time of purchase or offered as an upgrade without requiring a field visit or reprogramming of the meter or affecting the warranty or battery life. J.RF Communications Module 1. The meter and RF communication module shall be one single integrated unit hermetically sealed. 2. The meter shall be capable of communicating in both AMR and AMI modes. 3. AMR communications shall utilize an unlicensed 912.5-918.5 MHz frequency range. 4. AMI communications shall utilize an FCC assigned frequency within the licensed 450-470 MHz frequency range. K. Data Logging 1. The meter shall store data logs in the internal memory. These logs shall be easily retrievable via a mobile app and displayed graphically in the headend system
