M33 provides information about the most common flowmeters used in water treatment and custody-transfer applications, including the Venturi, modified Venturi, orifice plate, electromagnetic, turbine and propeller, transit-time ultrasonic, vortex, averaging Pitot, and averaging insertable electromagnetic. The discussion of these meters covers basic theory, installation and maintenance. General concepts applicable to flowmeters are also covered, including flow characteristics, performance issues, communication, information and signal outputs, and flowmeter selection.

This third edition of M22 contains information needed to estimate customer demand and maximum expected flow that can be used to size new service lines and meters. This edition expands the ways to approach the sizing of water service lines and meters and offers improved methods for the sizing of dedicated irrigation meters. M22 includes a useful field method called demand profiling that can be used to evaluate actual customer use patterns and help optimize meter size selection. The data presented in M22 were obtained from field measurements, utility surveys, technical publications, and hydraulic design calculations. This manual emphasizes that utilities having more information about a specific sizing situation will result in the best sizing decision from the tap to the meter. This information has been condensed into a simplified format to assist readers in addressing most common service conditions. The methods contained in this manual are appropriate for water utility managers, engineers, planners, technicians, field operations personnel, and consultants involved with designing and constructing projects requiring water service.

Annotation A guide to selecting, installing, testing, and maintaining water meters. Coverage includes selecting meter types, impacts on service adequacy, meter installation, testing of meters, and maintenance and repair of displacement meters. Also discusses shop layout and equipment, records, and remote registration. Includes a list of AWWA manuals. This manual discusses recommended practices; it is not an AWWA standard calling for compliance with certain specifications. Can be used by new and existing utilities of all sizes, and by design engineers and consultants. Member price $40.00. Annotation copyrighted by Book News, Inc., Portland, OR.

This AWWA manual of practice provides information on the factors that influence pipe corrosion, assessing corrosion-related impacts, water quality and implementation, and maintenance of an effective corrosion control program.

This operations manual explains the basic principles of electrical power distribution, automation, and instrumentation in water distribution, treatment, and storage systems. Chapters cover hydraulic and electrical principles, electric motor controls, measurement instruments and displays, pumps and valves, and automatic and digital controls.
