PTFM 6.1 PORTABLE TRANSIT TIME FLOW METER



PTFM 6.1 Portable Transit Time Flow Meter
Designed for challenging flow applications in industrial environments. Easily deployed whenever you need it. it only takes a few minutes to configure the PTFM 6.1 with your application parameters, install the transducers without interrupting your process, and begin measuring flow. With multiple transducer sets optimized for a wide range of pipe sizes and materials, new and more powerful signal processing hardware, standard factory calibration, and intuitive on-screen diagnostics, the PTFM 6.1 provides maximum confidence in the accuracy and reliability of your measurements.
 
Whether you need flow measurement when you didn’t have it before, or you need to prove that your existing system is performing properly, the PTFM 6.1 is here to help by providing accurate, non-invasive flow measurement in the most challenging industrial environments and applications, with minimal installation complexity and cost. With new and more powerful signal processing hardware, rugged IP67 design, and three interchangeable, non-invasive transducer sizes optimized for a wide range of pipe sizes and materials, the PTFM 6.1 is the right choice for your on-the-go or long-term flow measurement applications.

Set up the 12 million point data logger to store time and date-stamped flow readings from 10-second to 60-minute intervals. View the convenient on-screen Flow Report where total, minimum, maximum, and average flow rates are stored in a 24-hour daily summary for the last 365 days. Download the flow logs and 24-hour report data by inserting your USB drive into the meter. The included Greyline Logger software displays data in both graph and table formats with one-click export to Microsoft Excel, images, or CSV files for use in other programs.
