The Horizontal shaft alignment app is designed to be used with the SKF Shaft Alignment Tool TKSA 51 or TKSA 71. Together, the hardware and the app form an alignment system that allows shaft alignments of many rotating machines to be made in an intuitive and easy way. The system uses line laser to PSD technology that enables highly accurate and reliable shaft alignments. The hardware and its app communicate wirelessly via Bluetooth®. Without the hardware the app can nonetheless be used, as it features a fully functional demonstration mode allowing the complete alignment process to be experienced before purchasing the TKSA 51 or TKSA 71 instrument. KEY FEATURES: • Very easy-to-use – The Horizontal shaft alignment app focuses on making the main alignment tasks as easy as possible and enabling accurate shaft alignments. • Full measurement flexibility – The Horizontal shaft alignment app uses a flexible three position measurement method that allows measurements to start at any angle and if the space is limited alignments can be performed with a total of 40° rotation only. • Demonstration mode – The Horizontal shaft alignment app offers a fully functional demonstration mode allowing the complete alignment process to be experienced before purchasing a supported SKF Shaft Alignment Tool. • Automatic alignment report – Automatically generated alignment reports give a complete overview of the alignment process and results. The reports can be customised with additional notes, a machine picture, a signature and can easily be shared via email or cloud services. • Explanatory videos – Easy to follow videos demonstrating how to set up and perform accurate measurements using the TKSA 51 or TKSA 71. • 3D Animations – 3D animations guide the user through the alignment process, allowing accurate shaft alignment to be performed in a very easy way. • Machine library and QR code scanner – Helps keeping track of the machines that have been measured. Machine information like distances, the machine picture, and other details are saved for each machine and can be reused the next time the same machine is measured. QR codes can be scanned to identify a machine and quickly retrieve its details. The library can also be used for easy access to all the reports generated for each machine in one place. HARDWARE – SKF Shaft Alignment Tool TKSA 51 and TKSA 71: The SKF TKSA 51 and TKSA 71 systems use a pair of measurement units that are combined with laser transmitter and detectors to measure and correct shaft alignment with high accuracy and reliability. The data is transferred in real time through Bluetooth® 4.0 LE to the app. IMPORTANT NOTE: This app is designed to be used with the SKF Shaft Alignment Tool TKSA 51 or TKSA 71 hardware. The SKF TKSA 51 or TKSA 71 can be purchased separately from your local SKF Authorized Distributor.

Pipe Flow Liquid Flow Rate is a flowrate calculator app from Pipe Flow Software that calculates the fluid flow rate in a pipe for a given pressure loss (includes friction losses and fitting losses). It uses the Darcy-Weisbach equation with Colebrook-White friction factors, together with K values for fittings, to provide accurate calculations. Pipe Flow Software applications are used by engineers in over 100 countries worldwide. The Liquid Flow Rate App has an intuitive user interface that allows for easy entry of input data, including changes in elevation, and selection of valves & fittings. Comprehensive results include Reynolds number, friction factor, friction losses, fitting losses, fluid velocities and more. Each result is clearly displayed using expandable sections that reveal further information as needed. Users can select pipe materials, pipe diameters, pipe fittings (k factors) and liquids from the integrated databases, and these can also be extended with user specific data for custom pipe materials, diameters, fittings, and liquids. The App can operate in Imperial or Metric units and each individual field can be further customised to use a specific unit. Results values can be displayed to a specified number of decimal places. The Liquid Flow Rate calculation results have been verified against multiple cases of published data from well known sources. The results of these calculations are included in the Results Verification PDF document which can be accessed from within the App. Engineers can easily perform their flow rate calculations in the office or on site. Professional Excel and PDF reports can easily be shared with others. Results can also be saved to the library within the App. The Pipe Flow Liquid Flow Rate software has unrivalled functions and features: - Liquid properties database for water, oils, acids, and other fluids. - Pipe material database for various Steel, Aluminium, Copper, HDPE, and other pipes. - Fitting database for standard valves and bends, with associated K factor values. - User definable custom materials, fluids and fittings. - Professional Excel and PDF reports showing calculation results. - Results verification against published data to provide confidence in the calculation results. - Configurable post decimals for display on screen and in reports. - Automatic conversion between a wide range of units. - Compatibility with Pipe Flow Wizard files for iOS, macOS and Windows. - Calculations based on the same reliable calculation engine that is used by Pipe Flow Software's premier Pipe Flow Expert software, which is trusted by users in over 100 countries worldwide. - High quality, reliable software, and unrivalled customer support. Pipe Flow Liquid Flow Rate is offered as a free trial download and can be purchased for a one-time fee within the App. Terms of Use: https://www.pipeflow.com/pipe-flow-mobile-software/pipe-flow-mobile-software-license-terms
