Description
Hach AV9000 Analyzer Module
The AV9000 Analyzer's factory default settings have been carefully selected to streamline set-up, maximize battery life, and provide reliable flow data even in the most difficult sites. This accessory module is for difficult sites and for users who need in-depth analysis and custom settings. A full set of diagnostic tools and the advanced architecture of the AV9000 Area Velocity Analyzer facilitate collection of useful flow data.
Advanced Diagnostic Tools and Settings for Difficult Sites
The AV9000 Analyzer's factory default settings have been carefully selected to streamline set-up, maximize battery life, and provide reliable data even in the most difficult sites. For difficult sites and for users who need in-depth analysis and custom settings, the full set of diagnostic tools and advanced architecture of the AV9000 Area Velocity Analyzer facilitate collection of useful flow data. A quick graph shows, on demand, the Doppler spectrum and validates measurement quality. New quality and diagnostic parameters may be logged alongside the flow data.
Improved Accuracy
The AV9000 Area Velocity Analyzer is compensated for temperature, thus eliminating potential velocity error of 2.7% over a 10°C seasonal swing*. Its advanced multi-scale digital Doppler analysis provides the optimal combination of resolution and noise immunity. Mirror Image Processing™ eliminates sign errors and the advanced Target Set Processing™ reduces the impact of dominant targets (particles) in the stream to deliver a more representative velocity. More accurate data produces more accurate billing. *Calculated on a baseline temperature 10°C, assuming ±5°C shift between seasons. Note: Mirror Processing™ and Target Set Processing™ are patent-pending.
Confidence in Your Data
Real time sensor diagnostic feedback and measurement flags provide data confidence before you leave the site, which minimizes the risk of missing an event. The LED indicator on the FL900 Series Logger will verify correct programming sensor set-up and telemetry success or failure.
Less Maintenance and Troubleshooting
Submerged AV sensors are available with either oil-filled or non-oil filled cover plates. The oil-filled models are disigned for sites susceptible to fouling. The cavity is filled with high viscosity silicon oil to reduce the collection of sand, silt and grit on the pressure transducer. Use the non-oil-filled cover plate model in sites where the pipe could run dry.
Area Velocity Data on the Web
When using the AV9000 and a cellular modem (optional) with the Hach FL900 Series Flow Logger,you can get real-time Area velocity flow data on the internet, make remote programming changes and define site-specific alarm conditions to receive an alert on your cell phone or by e-mail.
