Smart Flow

Pentair Aquatic Eco-Systems offers the VAKI Smart Flow System to enable users to gather and store information about all measured fish for easy comparisons of size and number. This facilitates the optimization of every operation as VAKI devices can be controlled and fine-tuned using Smart Flow in order to achieve high levels of efficiency and accuracy.

    • Balanced biomass in all grades

The advanced software in VAKI products is used to count the fish as they pass the counting area. All fish images are stored and can be used for verifying the count. Automatically-generated reports provide users with valuable and detailed information for each counting session. The average weight and size distribution of the counted fish are shown on a graph along with information on the total biomass of the fish. VAKI products and their powerful software can provide counting reports detailing the total number of fish, the number in each group, the total counting time, the average fish sizes, and a summary of any counter overload time. The counting throughput graph is shown in the report, along with the name of site, tank number, company logo, comments, and more. With the optional size measurement function the average weight and size distribution is also included. A hard copy of the report can be printed or stored.

Macro App

Among other features the Macro app provides the user the option to run the counter, view the results and email the count report from a smart phone or tablet.

Counter Software

The touch pad screen on the counter head is used to operate the counter. The main screen of the program displays numbers, average weight and through put. A graph shows the rate of fish going through the counter and the maximum capacity. Should the counter be overloaded a warning signal is given. After each count an image file and a report file are saved. Files can be displayed on screen and transferred to a flash drive or internal network.

Recording of Images

The images of the fish are automatically recorded and can be used to validate and check the accuracy of the count. The image file can be given to a customer and/or stored as a permanent record. The red chart indicates the numbers of fish counted during the entire count and is used to select a time frame for further analyses. The screen displays images of fish passing the camera for each one second interval. Accuracy can be verified by a manual check of the number of fish images to the count shown on the screen.

Counting Report

The counting report is produced after each count with the total number of fish counted, number in each group, total counting time, average fish/min and any counter overload time. The counting throughput graph is shown on the report and the name of site, tank, company logo, comments, and other information can be included. With the optional size measurement function the average weight and size distribution is also included. A hard copy of the report can be printed or stored.

Size Measurements

An optional feature to the counting program, the size measurement module, presents accurate average weight and size distribution of the counted fish. In one simple operation complete data on number and size of fish is obtained without handling or stress.


Pentair Aquatic Eco-Systems VAKI Cloud is a web application that provides the user with an overview of detailed information and data from VAKI counters. Data from VAKI counters are created during each counting session, and are moved to a remote database. The VAKI Cloud web application enables authorized users the ability to view these data from anywhere, at any time. The VAKI Cloud is an extremely valuable tool that is utilized by commercial fish farming operations worldwide.
