AMS Instrumentation and Calibration presents the KATflow 150, an
advanced range of clamp-on ultrasonic flowmeters from Katronic, delivering flexibility
and performance to the user with a comprehensive specification and a list of
Featuring a practical modular design and offering a wide variety of
different transducer types, this instrument is suitable for everything from
simple water flow measurements to energy flow monitoring and automated process
The KATflow non-invasive flowmeters work on the transit time ultrasonic
principle. This involves sending and receiving ultrasonic pulses from a pair of
sensors and examining the time difference in the signal. Katronic uses clamp-on
transducers that are mounted externally on the surface of the pipe and generate
pulses that pass through the pipe wall. The flowing liquid within the pipe causes
time differences in the ultrasonic signals, which are then evaluated by the
flowmeter to produce an accurate flow measurement.
The key principle of the method applied is that sound waves travelling
with the flow will move faster than those travelling against it. The difference
in the transit time of these signals is proportional to the flow velocity of
the liquid and consequently, the flow rate.
Since elements such as flow profile, type of liquid and pipe material
will have an effect on the measurement, the flowmeter compensates for, and
adapts to changes in the medium in order to provide reliable results. The
instruments can be used in a variety of locations from measurements on
submarines to installations on systems destined for use in space, and on
process fluids ranging from purified water in the pharmaceutical sector to even
toxic chemical effluent. The flowmeters will operate on various pipe materials
and diameters over a range of 10mm to 6,500mm.
