Product Number: FL900AV.97
By pairing Hach's Sumberged AV Sensor with our state-of-the-art Hach AV9000 Analyzer Module, you create a powerful Hach Submerged Area Velocity Meter (FL900AV) which provides "cleaner", more precise data than ever before.
Our Submerged AV Sensor (sold separately) is a robust, 1 MHz Acoustic Doppler velocity sensor designed to measure wastewater flow with improved accuracy and reliability. This tried-and-true sensor also uses a pressure transducer to measure flow level and incorporates advanced technologies to ensure precision, including automatically correcting for temperature and velocity effects on measurements. With advanced signal processing and filtering options, the AV9000 Analyzer Module expands the applicability of the sensor into more difficult applications. Plus, advanced analyzer diagnostics, including capture and display of the Doppler spectra, allow you to verify that the sensor is working properly even before you leave the site, giving you peace of mind.
The AV9000 Area Velocity Analyzer module is compensated
for temperature, thus eliminating potential velocity
errors of 2.7% over a 10ºC 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.
With the time saving features designed into the FL900 Flow Loggers, crews spend less time in the manhole and less time on site to decrease monitoring costs while increasing the safety of flow monitoring crews.

The logger can be quickly attached to a wall, pole or manhole ladder in minutes. Users can choose to hang logger from standard carabiner or optional 4-bolt wall mount for pole, horizontal or vertical wall mount or ladder rung mount.
