  • compact Clamp-on Micro flow meter
  • Micro Clamp-on flow sensor

RBFM-EX3 Compact Clamp-on Ultrasonic Flow/Heat Meter(Clamp-on Micro Flow Sensor) is special design for compact clamp-on small pipe, the pipe range is from DN10 - DN100, it's 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. It can save much cost for installation. No need for tubes of ultrasonic grease, rulers and marker pens. Clean, hassle-free installation.
