Ultrasonic Flowmeter
KATflow 230
Description
The KATflow range of non-invasive flowmeters utilises
ultrasonic technology for the accurate flow measurement
of liquids and liquified gases in full pipes.
The KATflow 230 is designed for portable use to meet the
needs of the Service/Maintenance and Commissioning
Engineer wishing to check the flow rate at different
locations in the plant. The set-up of the unit is simple
through a setup wizard in order to obtain the required flow
information in minutes.
The measurement of flow is based on the principle that
sound waves are influenced by a flowing medium.
Measurements are made by penetrating the pipe with
ultrasound and subsequently time differences, frequency
variations and phase shifts of the ultrasonic signals are
evaluated.
The ultrasonic sensors are clamped onto the outside of
the pipe, thus eliminating the need to dismantle the
pipework and interrupt the process. The KATflow 230
can be applied to any type of standard pipe carrying
clean or dirty liquids and liquified gases.
Advantages
• Low installation effort and costs
• Measurement is independent of fluid conductivity
• No pressure loss, no possibility of leakage
• Retrospective installation for existing plants
possible
• No cutting of pipes necessary, no interruption of
process, no plant shut down
• No additional fittings for maintenance required
• Hygienic measurement, no risk of contamination,
suitable for ultra clean liquids
• No contact with medium, no risk of corrosion when
used with aggressive media
• Cost advantages when used with large diameter
pipes, high pressure systems, etc.
