Dynasonics manufactures a complete line of ultrasonic flow measurement equipment, including portable, fixed position and multi-channel transit time and Doppler flow meters. These meters are ideal for full pipe, liquid flow applications; they are non-invasive and provide a high degree of accuracy (better than +/- 1% in many cases). Suited for a wide range of pipe materials, in pipe diameters from 1/4" (6.35 mm) to over 120" (3,048 mm), these meters are designed for long service life and low maintenance cost. Additional Dynasonics products include insertion magnetic and heat flow meters.
