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.

Long Battery Life

Reduce site visits to change batteries with FL900’s long battery life. The estimated battery life at 15 minute intervals is 185 days for the Flo-Dar sensor and 306 days for the Flo-Tote 3 sensor

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.

Plug and Play Sensor Ports

The FL900 Series Flow Logger is available with 2 sensor ports. The logger auto-detects the type of sensor connected to allow customers maximum flexibility for their Hach flow sensor inventories.
