Welcome to AquaCalc!
JBS Instruments is now a division of AquaCalc LLC and continues to manufacture the AquaCalc stream flow computer, a portable electronic device that automates the measurement of water flow in streams and rivers and canals, also know as open channel discharge measurements. The AquaCalc is used with mechanical current meters such as the Price AA meter and the Pygmy current meters manufactured by Performance Results Plus (formerly Rickly Hydrological) and Gurley Precision Instruments.

This device is used by hydrologists and field biologists to make stream flow and open-channel discharge measurements.
AquaCalc DataLink
The AquaCalc DataLink program is used to download measurements from your AquaCalc. This version includes the ability to automatically download measurements from the AquaCalc Pro Plus, review measurements using interactive charts, print reports, export to other file formats and access the AquaCalc Excel Analyzer.
The AquaCalc Pro Plus includes rechargeable batteries, a USB connection, and an easier user interface.
The AquaCalc is the industry standard for stream-measurement technology using current meters, and is widely used by the U.S. Geological Survey, and hydrographers world-wide
Compare Cost and Accuracy with other Wading Discharge Measurement Devices and Technologies
When used with USGS style Price AA and Pygmy current meters, the AquaCalc is more cost effective, with comparable accuracy, to other equipment such as the FlowTracker (tm).
See the USGS HIF Analysis of Costs and Accuracy here!
When used with industry standard USGS style mechanical current meters, the AquaCalc is an accurate and cost-effective digital solution to stream-flow measurement.
This is the standard against which all other technologies are measured.
