JBS Instruments is now a division of AquaCalc LLC and specializes in the creation of portable stream flow measurement devices like the AquaCalc Pro Plus and the AquaCalc 5000. These instruments are used along with mechanical current meters by hydrographers and biologists to measure the amount of water flowing in streams, rivers and other open channels.

The AquaCalc Pro Plus

With a large display and improved user interface it’s the next generation of automated stream flow measurement computers.

This device is used in wading measurements and suspended measurements using mechanical current meters, USGS mid-section method protocols and approved equipment.
