Hach FH950 Portable Flow Meter

The lightweight, battery-powered FH950 Velocity Flow Meter was designed to provide accurate velocity measurements while simplifying the entire measurement process in rugged field environments. Multiple user-friendly features designed into the FH950 allow you to quickly and easily determine stream velocities for required discharge measurements, or use the FH950 to calibrate area velocity flow meters, or verify primary devices such as weirs and flumes.
The FH950 Velocity Meter simplifies set up, displays real time data and trend information, auto-calculates discharge volumes and eliminates the need for manual recording with its convenient USB to PC data download; with no moving parts, the sensor never requires mechanical maintenance.  The Hach FH950 replaces the Marsh Mcbirney Flo Mate 2000.
