The AquaCalc 5000 uses a two line display in a water-resistant case. It displays revolutions, elapsed time, velocity, distance and depth for each station. It calculates total stream discharge at the push of the button.

The AquaCount eliminates the use of headphones and stopwatches by counting the revolutions and calculating velocity when used with Price-type AA and Pygmy current meters. Unlike the more adavanced AquaCalcs, it does not store or calculate discharge. It

The AquaCalc Pro Plus

The AquaCalc Pro Plus is an improved version of this popular open-channel discharge measurement device used by hydrologists and hydrological technicians worldwide.

It is portable field computer that is used along with mechanical current meters for the measurement of stream-flow and discharge. It replaces the old head-set and stopwatch method of measuring streams and moves the modern hydrographer into the information age. With greater accuracy and the ability to export data to a variety of computer based programs for improved data management and quality control the AquaCalc makes your open-channel measurements better.

The AquaCalc can assist technicians in making high-quality measurements based on United States Geological Survey (USGS) discharge measurement standards and techniques.

The AquaCalc Pro Plus model combines a large display, expanded keypad, water-resistant case, rechargeable batteries and easy-to-use software with automated USB downloading and review software called DataLink.
