Details :
The Flo-Dar Family of flowmeters provides a revolutionary approach to open channel flow monitoring. Flo-Dar combines digital Doppler radar velocity-sensing technology with ultrasonic pulse echo level sensing to remotely measure open channel flows.
The FLO-DAR™ sensor is positioned above the flow thereby avoiding all the problems associated with traditional flowmeters when the sensor is immersed in the flow.
The model 4000SR can be fixed up to 1.5 meter above the water surface.
Benefits of the FLO-DAR™ flowmeter include:
Personnel have no contact with the flow
One-time entry into confined space for installation/removal
Easy installation
Maintenance caused by immersed sensor is eliminated

Set-Up/Data Retrieval
Flo-Ware for Windows software is the user on-site set-up, data management, and report generation software. It is compatible with desktop/portable computers utilizing Windows 95 / 98 / 2000 / Me / NT / XP. Flo-Ware for Windows software can retrieve data from both Flo-Tote and Flo-Dar Flowmeters. Flo-Ware FX for the PocketPC has all of the same functionality as Flo-Ware for Windows with the exception of report generation.
