PTFM 6.1 Portable Transit Time Flow Meter
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.
For clean fluids in full pipes, with typically less than 2% by-volume concentration of solids or bubbles. Also suitable for wastewater or sludge flows with low solids concentration.
