AccuFlux® Integrity Tester

Automated integrity test instrument.

Consistent with Meissner’s commitment to developing smart products that bolster quality, reduce risk and provide a second to none customer experience, the AccuFlux® integrity test system is engineered to combine the highest levels of instrument accuracy, robustness, and ease of use. In an era where importance of quality and accuracy often takes a back seat to reducing cost, the AccuFlux® stays true to its purpose of sacrificing nothing; providing assurance that each test performed is being done so in a way that only a company with over 30 years of filtration expertise can provide.

The AccuFlux® is a testament to Meissner’s commitment to vertical integration. Key among the design of this system is a 15″ color, multi-touch user interface which serves as a window into the intuitive and easy to use nature of the system. The AccuFlux® features a recipe driven test setup which allows a user to be performing tests within seconds of powering on the device. Once powered up, the user logs directly into the test screen where a test recipe can be selected. After reviewing conveniently displayed test data, the user can start the test with the press of a button. While the test is being performed, all test settings and data are being stored to up to three (3) locations. Upon completion of a test, the user must acknowledge the result, at which point a test report is generated and saved to a .PDF file. These files as well as the test data can also be viewed from the system’s History screen. Setup of recipes is made simple by providing data for all supported Meissner filters. The system is compatible with filters from other manufacturers, although this data must be entered manually. Test data entry and recipe setup is limited to users of specified permission level. A portion of what makes the system CFR 21, Part 11 compliant is its multi-tiered user administration system which requires all users to have a unique, individual username and password. The user experience and usability of the system is also enhanced with various features listed below:

Preinstalled filter data for Meissner filtersBuilt in self checks and tests, such as internal/external leak test and source pressure checkBuilt in sensor calibration utility
Auto-generated detailed PDF test certificateEditable test data for adding non-Meissner filterMultiple save locations, including network locations and USB devices
CFR 21 Part 11 CompliantLive test data stored to .CSV fileRecipe storage system for storing filter data, system data and test setups
Tiered user system including unique user login accounts

What's Under the Hood

When designing the AccuFlux®, quality and performance were the number one priority. The result is a system comprised of up to three (3) highly accurate mass flow meters, providing the greatest level of accuracy at all points throughout the standard 0-250 mL/min flow range. The high level of flow control built into the system allows the diffusive flow tests to be performed in less than 3 minutes, without sacrificing accuracy, and on systems containing as many as three 40″ filter elements. Bubble point tests are performed using a highly accurate pressure sensor and utilize Meissner’s TransVector™ algorithm, completing bubble points tests in as little as 90 seconds.

AccuFlux® employs a Quad core, Windows 10 industrial PC with integrated 15″ full color, multi-touch screen. The use of a powerful PC is a must when running today’s anti-virus software, and also yields great benefits when it comes to integrating the system with a network, using standard Windows based accessories or applications, and connecting the system to other network devices and printers. Some of the features that allow the AccuFlux® to perform at such a high level are:
