Reliable, Budget-Saving Monitoring

The FL900 Flow Logger provides users with a reliable, budget saving solution for open channel portable flow monitoring applications. The robust logger’s time-saving features will drastically decrease site time and increase safety for monitoring crews. The Logger LED provides instant communication verification of correct site set-up and flow meter communication prior to leaving the site.

Increase Monitoring Crew Safety

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.

Improved Accuracy

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.

Easy Installation/Versatile Mounting Options

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.

The Power of Wireless

Eliminate risk by using wirelessly transmitted flow data to make smarter, real-time decisions regarding your collection system. With wireless-enabled models, you’ll receive alarms, via email or text, alerting you to any concerns at your monitoring sites. Plus, using FSDATA Online Data Manager, you’ll have secure 24/7 access to your flow data and wireless meter from the comfort of the internet. With FSDATA, site visits to collect flow data or to adjust meter settings are eliminated, decreasing maintenance costs. And you can set alarms and view sensor diagnostics remotely to maximize uptime. That’s the power of wireless.
