Accusonic Technologies” Model 7700-7720 18-path flow measurement system meets ASME PTC 18-2002 requirements and is the largest integrated real-time flowmeter network system available with transit-time technology for hydroelectric and fossil power plant applications. The flowmeter is capable of measuring up to 10 paths from a single console. It can also be networked into a flowmeter system with the Model 7700 Master Control Unit, connecting up to a total of 16 flowmeters. Each flowmeter in the system can monitor four separate pipes and/or channels, providing an integrated flow measurement system for up to 64 separate flow measurement and monitoring sections. Measurable pipe/channel sizes range from eight inches (200 mm) to 500 feet (150 m). Utilizing multiple-path, chordal, transit-time technology, achievable accuracy is +/- 0.5 percent in full pipes and +/- 2.0 percent in partially full pipes and channels (even in the presence of flow profile distortions and cross flow). A flexible offering of Accusonic transducers is available including designs for hazardous area installations, exposed pipes of all materials, buried or encased pipes, and pipes and channels that cannot be dewatered.
