Ductus TT COHP
Ultrasonic multipath flowmeter
A further area of application is the detection of burst pipes. Here, at least two systems have to be permanently installed in the pipelines to be monitored. Because of the accuracy of our products even small leakages can be detected instantaneously.

Advantages of Clamp-On Systems
A flow meter using clamp-on transducers makes measuring discharge non-intrusive and easy from the outside of the pipe. The transducers are installed with little technical effort and without process interruption on the pipeline.
Rotationally symmetric flow profiles can be determined with a single acoustic path; non-symmetric profiles require the use of several acoustic paths.
