I have attached herein the data sheet for these models. <br /> <br />Per ISO Standard 4064 Section 4.1: <br />Permanent flow rate Q3 is the highest flow rate within the rated operating conditions at which the <br />water meter is required to operate in a satisfactory manner within the maximum permissible error. <br /> <br /> <br /> <br />Therefore, Q3 shall be considered equivalent to maximum continuous flow for design and evaluation <br />purposes. These flow rates are also in conformance with the AWWA C715 standards and maintain a <br />warranty for accuracy across all ranges of flow measurement. <br /> <br />We are committed to providing the City of Pleasanton with high quality customer service. If you have <br />any questions or concerns, please do not hesitate to contact me using the information below. <br /> <br />Sincerely, <br /> <br /> <br /> <br />Jess S Bromley <br />VP Sales, Americas <br />Kamstrup Water Metering <br />Email: jeby@kamstrup.com <br />Phone: (216) 308-3517
