Product Announcement from Gurley Precision Instruments
Upgrade headphone and optical style outfits to compute total flow.
Features and advantages include:
More efficient stream flow calculations (an average of 20 minutes per cross-section). Reduces operator error by automatically computing formulas. Weather resistant. Standard computer output is similar to USGS' 'black sheet'. Optional software can plot data in graph format.
The AquaCalc 5000 is a handheld device that measures, records and calculates velocity and total flow measurements. The user inputs the distance and depth, while the AquaCalc measures the revolutions and time, thus calculating the velocity and total discharge.
Optional accessories include:
Rod mount: attaches the indicator to a top-setting wading rod
Advanced firmware - this upgrade includes additional procedures requested by the USGS to:
1) improve accuracy in troublesome conditions
2) add/delete stations while testing
3) extended vertical measurements
4) perform ice measurements
5) display available memory
6) recognize incorrect meter and/or sounding weight used
