Product overview
The FL900 series flow loggers are used in open-channel flow monitoring studies such as inflow &
infiltration (I&I), combined sewer overflow (CSO), capacity and planning and storm water runoff
monitoring.
Data is collected from attached sensors and logged for future retrieval. The sensors can be added or
changed in the field. Depending on the model, up to four sensors can be connected. The data can be
retrieved directly through a USB or RS232 cable or remotely through a wireless network with
FSDATA Desktop and FSDATA server software. The FL900 Series loggers can also connect to an
external power source, rain gauge or be used to pace a Sigma or Hach sampler.
The wireless option and the number of available connectors varies with the model of the logger.
