KATflow 100 2 Introduction

2 Introduction

The KATflow 100 is an ultrasonic flow transmitter employin clamp-on sensors for

the measurement of liquids in full, enclosed pipes. Flow measurements can be un-

dertaken without interruption of the process or interference with the inte rity of the

pipeline. The clamp-on sensors are attached to the outside of the pipes. The KAT-

flow 100 uses ultrasonic si nals for measurement of the flow, employin the transit-

time method.

Ultrasonic si nals are emitted by a transducer installed on a pipe and received by a

second transducer. These si nals are emitted alternately in the direction of flow and

a ainst it. Because the medium is flowin , the transit time of the sound si nals

propa atin in the direction of flow is shorter than the transit time of the si nal

propa atin a ainst the direction of flow. The transit-time difference ΔT is meas-

ured and allows the determination of the avera e flow velocity alon the path of

acoustic propa ation. A profile correction is then performed to obtain the avera e

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 openin the box containin the flowmeter, any mark-

in s or warnin s shown on the packa in should be observed prior to openin . The

followin steps should then be taken:

●Unpack the flowmeter in a dry area.

●The flowmeter should be handled with care and not left in an area where it

could be subject to physical shocks.

●If usin a knife to remove packa in care should be taken not to dama e

the flowmeter or cables.

●The flowmeter packa e and contents should be checked a ainst the deliv-

ery note supplied and any missin items reported immediately.

●The flowmeter packa e and contents should be checked for si ns of dam-

a e durin transport and any problems reported immediately.

●The vendor accepts no responsibility for dama e or injury caused durin

the unpackin of the instrumentation supplied.

●Excess packin materials should be either recycled or disposed of in a suit-

able way.

3.1.2 Storage

If stora e 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 dama e,

●small items should be kept to ether in the ba s provided to avoid loss.

3.1.3 Identification of components

The followin items are typically supplied (please refer to your delivery note for a

detailed description):

●KATflow 100 ultrasonic flow transmitter

●Clamp-on sensors (one pair for sin le channel operation, two pairs for dual

channel operation)

●Sensor connection cable(s) if not direct sensor connection

●Sensor mountin accessories

●Couplin component

●Operatin instructions

●Project and/or hazardous area documentation (optional)

●Calibration certificate(s) (optional)

3.2 lamp-on sensor installation

The correct selection of the sensor location is crucial for achievin reliable meas-

urements and hi h accuracy. Measurement must take place on a pipe in which

sound can propa ate (see Acoustic propa ation) and in which a rotationally sym-

metrical flow profile is fully developed (see Strai ht pipe len ths).

The correct positionin of the transducers is an essential condition for error-free

measurements. It ensures that the sound si nal will be received under optimal con-

ditions and evaluated correctly. Because of the variety of applications and the differ-

ent factors influencin the measurement, there can be no standard solution for the

positionin of the transducers.

The correct position of the transducers will be influenced by the followin factors:

●diameter, material, linin , wall thickness and eneral condition of the pipe,

●the medium flowin in the pipe,

●the presence of as bubbles and solid particles in the medium.

Check that the temperature at the selected location is within the operatin temper-

ature ran e of the transducers (see Specification).

After the sensor location has been selected, make sure that that supplied cable is

lon enou h to reach the flow transmitter mountin location. Ensure that the tem-

perature at the selected location is within the ambient operatin temperature ran e

of the flow transmitter (see Specification).

Acoustic propa ation is achieved when the flowmeter is able to receive sufficient

si nal from the transmitted ultrasonic pulses. The si nals are attenuated in the

pipe material, the medium and at each of the interfaces and reflections. External

and internal pipe corrosion, solid particles and as content in the medium contribute

heavily to si nal attenuation.

Sufficient strai ht len ths of pipe on the inlet and outlet of the measurin location

ensure an axi-symmetrical flow profile in the pipe, which is required for ood meas-

urement accuracy. If insufficient strai ht len ths of pipe are available for your ap-

plication measurements are still obtainable, but the certainty of the measurement

can be reduced.

3.3 Installation location

Select an installation location followin the recommendations in Table 1 and try to

avoid measurin

●in the vicinity of deformations and defects of the pipe,

●near weldin seams,

●where deposits could be buildin up in the pipe.

For a horizontal pipe:

Select a location where the transducers can be mounted on the side of the pipe, so that the sound waves emitted by

the transducers propa ate horizontally in the pipe. In this way, the solid particles deposited on the bottom of the pipe

and the as pockets developin at the top will not influence the propa ation of the si nal.

Straight pipe lengths

KATflow 100 3 Installation

For a free inlet or outlet pipe section:

Select the measurin point at a location where the pipe cannot run empty.

Correct Disadvantageous

For a vertical pipe:

Select the measurin point at a location where the liquid flows upward to ensure that the pipe is completely filled.

Correct Incorrect

Look for a sensor installation location with sufficient strai ht pipe to obtain accurate

measurements. Please refer to Table 2 as a uideline for recommended distances

from disturbance sources.

Disturbance source: 90°-elbow

L ≥ 10 D L ≥ 5 D

Disturbance source: 2 x 90°-elbows in one plane

Inlet Outlet

L ≥ 25 D L ≥ 5 D
