SITRANS FUS1010 (Standard)

FUS1010 Clamp-on ultrasonic flow meter

Clamp-on ultrasonic flow meter

SITRANS FUS1010, the most versatile clamp-on ultrasonic flow meter available, can operate in either WideBeam transit time or Doppler mode.  There is no need to change the meter when operating conditions change. This makes it suitable for virtually any liquid, even those with high aeration or suspended solids.

The SITRANS FUS1010 is available in single, dual and optional four channel/path configurations. There are three enclosures to choose from: wall mount, wall mount explosionproof and compact explosionproof.


Application examples include raw and potable water, effluent, condensers, chillers, nuclear, process control and batching.


Pair the SITRANS FUS1010 with the SITRANS F US Thickness Gauge to ensure precise flow measurement.


  • Accommodates shifting measurement conditions necessitated by presence of high aeration or suspended solids (dual mode)
  • Ensures higher accuracy by allowing two sets of sensors to be set up on one pipe and averaged (dual path)
  • Reduces capital cost with four channel version that allows simultaneous measurement of four independent pipesMeasures a wide variety of liquid applications
