Compact Ultrasonic Flow Heat Meter

RBFM-K Compact Clamp-on Ultrasonic Flow and Heat Meter is quick and easy to install, even by non-trained operators, the clam-shell design of this range makes them a fast and reliable solution for non invasive flow and/or heat measurement applications. As the sensor seperation distance is fixed, there is no need for adjustment and once fitted they are not easily disturbed. RBFM-K is special designed for small pipe size.
