1 3 Warranty
•Any product purchased from Katronic is warranted in accordance with the relevant product documentation and as
specified in the sales contract provided This is subject to the condition that it has been used for the purpose for which
it has been designed and operated as outlined in these operating instructions Misuse of the equipment will immedi-
ately revoke any warranty given or implied
•Responsibility for suitability and intended use of this ultrasonic flowmeter rests solely with the user Improper installa-
tion and operation of the flowmeter may lead to a loss of warranty
•Please note that there are no operator-serviceable parts inside the equipment Any unauthorised interference with the
product will invalidate the warranty
1 4 Return policy
If the flowmeter has been diagnosed to have a problem, it can be returned to Katronic for repair using the Customer Re-
turn Note (CRN) attached to the Appendix of this manual Katronic regret that for health and safety reasons we cannot ac-
cept the return of the equipment unless accompanied by the completed CRN
1 5 Legislative requirements
CE Marking
The flowmeter is designed to meet the safety requirements in accordance with sound
engineering practice It has been tested and has le the factory in a condition in which it
is safe to operate The equipment is in conformity with the statutory requirements of the
EC directive and complies with applicable regulations and standards for electrical safety
EN 61010 and electromagnetic compatibility EN 61326 A CE Declaration of Conformity
has been issued in that respect, a copy of which can be found in the Appendix of these
operating instructions
WEEE Directive
The Waste Electrical and Electronic Equipment Directive (WEEE Directive 2012/19/EU)
aims to minimise the impact of electrical and electronic goods on the environment by
increasing re-use and recycling and by reducing the amount of WEEE going to landfill It
seeks to achieve this by making producers responsible for financing the collection, treat-
ment, and recovery of waste electrical equipment, and by obliging distributors to allow
consumers to return their waste equipment free of charge Katronic oers its customers
the possibility of returning unused and obsolete equipment for correct disposal and re-
cycling The dustbin symbol indicates that when the last user wishes to discard this
product, it must be sent to appropriate facilities for recovery and recycling By not dis-
carding this product along with other household-type waste, the volume of waste sent to
incinerators or landfills will be reduced and natural resources will be conserved Please
use the Customer Return Note (CRN) in the Appendix for return to Katronic
RoHS Directive All products manufactured by Katronic are compliant with the relevant aspects of the
RoHS Directive

INTRODUCTION
2 INTRODUCTION
2 1 Clamp-on transit-time flowmeter
The KATflow 230 is a portable, battery operated ultrasonic flowmeter employing clamp-on sensors for the measurement
of liquids in full, enclosed pipes Flow measurements can be undertaken without interruption of the process or interfer-
ence with the integrity of the pipeline The clamp-on sensors are attached to the outside of the pipes The KATflow 230
uses ultrasonic signals for measurement of the flow, employing the transit-time method

2 2 Measuring principle
Ultrasonic signals are emitted by a transducer installed on a pipe and received by a second transducer These signals are
emitted alternately in the direction of flow and against it Because the medium is flowing, the transit time of the sound sig -
nals propagating in the direction of flow is shorter than the transit time of the signal propagating against the direction of
flow The transit-time dierence ∆t is measured and allows the determination of the average flow velocity along the path
of acoustic propagation A profile correction is then performed to obtain the average flow velocity over the cross-sectional
area of the pipe, which is proportional to the volumetric flow rate

3 1 Unpacking and storage
3 1 1 Unpacking
Care should be taken when opening the box containing the flowmeter, any markings or warnings shown on the packaging
should be observed prior to opening The following steps should then be taken:
•Unpack the flowmeter in a dry area
•The flowmeter should be handled with care and not le in an area where it could be subject to physical shocks
•If using a knife to remove packaging care should be taken not to damage the flowmeter or cables
•The flowmeter package and contents should be checked against the delivery note supplied and any missing items re-
ported immediately
•The flowmeter package and contents should be checked for signs of damage during transport and any problems re-
ported immediately
•The vendor accepts no responsibility for damage or injury caused during the unpacking of the instrumentation sup-
plied
•Excess packing materials should be either recycled or disposed of in a suitable way
3 1 2 Storage
If storage is necessary, the flowmeter and sensors should be stored:
•in a secure location,
•away from water and harsh environmental conditions,
•in such a way as to avoid damage,
•small items should be kept together in the bags and small plastic boxes provided to avoid loss
