Introducing the AquaCalc Pro Plus!

APP on Rod white backgroundAquaCalc LLC  is pleased to offer an improved version of the AquaCalc Pro discharge computer: the AquaCalc Pro Plus. All the same features of the the industry standard AquaCalc Pro


The 25 key keypad puts the most used functions at your finger tips. For those of you who still wish to hear your meter “clicks”, the internal speaker will let you hear them without a headset, and can sound a tone when you press a key or when the AquaCalc displays a message.

The user interface has been designed to make taking stream discharge measurements easier. With the larger display it is possible to see up to three observations in a vertical on the same screen, plus measurement settings and messages. Plus a continuous display of estimated instantaneous velocity so that you can see what the stream is doing before you begin your “official” observation.

The menu system, combined with three “soft-keys”, whose functions can be changed as needed, give the user easy access to the AquaCalc’s capabilities.

APP_Computer_CupsHardware design includes a rugged case with full gaskets designed to withstand directed hard spray (international standard for water resistant of IP65), scratch resistant display lens, integrated USB port with protective cap, and a custom designed mounting bracket.

The AquaCalc’s measurements can be downloaded to a computer using the included AquaCalc DataLink and displayed in graphs and reports. The AquaCalc Excel Analyzer file will allow you to import and edit measurements after they have been downloaded to you computer.

AquaCalc: It counts the clicks and more.

Collecting stream data used to require juggling an armload of gadgets while counting clicks, writing notes, and performing calculations. Not any more.

Now there’s the AquaCalc, a handheld computer that measures, records and calculates data with minimal user input. No more pencil, notepad and current meter table. No more calculator and stopwatch. No more “counting the clicks.”

AquaCalc does it for you - -automatically. You input the depth and distance at each station. AquaCalc measures velocity and elapsed time. Then, AquaCalc calculates total stream discharge and mean velocity. After stream measurement is complete, you can upload the data to a laptop or personal computer. It’s the fastest, easiest, most accurate stream measurement instrument available today.

Faster, more accurate stream measurement.AquaCalc_Pro_Plus_on_Bridge_Crane2

AquaCalc improves the speed, accuracy and efficiency of your stream measurements. The user inputs the distance and depth. AquaCalc measures revolutions and elapsed time calculating velocity and discharge. When all the stations have been measured, simply press a button and AquaCalc gives you the total discharge and mean velocity. AquaCalc completely eliminates time-consuming hand calculations, saving an average of 20 minutes per cross section. You can save as much as two hours a day - enough time to measure another station.

AquaCalc saves even more time in error detection and re-calculation. With hand calculations, finding and correcting an error can take hours. But with AquaCalc, you can usually find and correct data entry errors in a few minutes.

Eliminates math and transcription errors.

With AquaCalc and accepted measurement procedures, the chance of error is virtually zero. Math errors are eliminated. To help prevent procedural errors, AquaCalc prompts the user with a “flag” when an unusual entry occurs. AquaCalc uploads the data to your laptop or personal computer, so transcription errors are eliminated. The result: highly accurate data with less time wasted finding and correcting errors.

Special features include:

Saves time in the office.

AquaCalc lets you upload your data to a laptop in the field or your personal computer in the office, eliminating data entry time. And, because there are no math errors, quality control review becomes a much simpler and quicker task.

Convenient in bad weather.

You’ll appreciate the AquaCalc even more in bad weather. No more soggy note paper with hard-to-read notes! AquaCalc is easy to use in all weather conditions. The AquaCAlc Pro Plus case has an international rating of IP-65, which provides protection against dust and direct water spray.

Durable construction.

AquaCalc is manufactured from high-quality materials to withstand the occasional drops, vibrations, pollutants, temperature extremes and humidity variations that occur with normal, everyday use. Its weather-resistant design will stand up to prolonged exposure to sunlight, rain, sleet and snow.

Table or graph output.

AquaCalc output looks similar to the USGS Measurement Notes Back Sheet. The included DataLink software can plot data in graph form, which can help inexperienced users understand the data at a glance.
