Display changes in totalization in one (1) cubic foot increments. <br />2. Provide an AMI output recording changes in totalization in one (1) cubic foot increments. <br />3. Any register/meter that provides an output to AMI greater than one (1) cubic foot such that the <br />minimum registered change in totalization is ten (10) cubic feet or greater will not be accepted. <br />8.2 Reverse Flow <br />All meters/registers shall be capable of detecting flow of water in the forward and reverse directions. <br />Detection of flow in the reverse direction shall be reasonably accurate or as accurate as flow in the <br />forward direction. The Proposer shall provide a statement, as an attachment to this bid, describing <br />the capability and/or accuracy of reverse flow for each meter model and size. Preference will be <br />given to proposed meter models that incorporate forward and reverse flow totalization in a single <br />register (either physical or electronic). <br />PUBLIC WORKS SERVICES DEPARTMENT <br />FY 2019-20 RESIDENTIAL AND COMMERCIAL COLD WATER METER PURCHASES RFP <br />(9/13/2019) 11 OF 27 <br />125 <br />
