• Avoid insta ation of sensors in the vicinity of deformations and pipe

defects, near we ding seams or where deposits cou d have accumu-

ated.

• Se ect a measuring point with sufficient straight pipe to obtain ac-

curate measurements. P ease consu t the manua for the recom-

mended distances from sources of disturbance.

• For a horizonta pipe, mount the sensors on the side of the pipe. For

a vertica pipe, mount the sensors at a ocation where the iquid

f ows upwards (Pic. 1).

• Mount the sensors in the direction of the f ow (Pic. 2).

• C ean the pipe at the measurement point. Remove oose paint and

rust with a wire brush or fi e.

• App y coup ing paste to the face of the c amp-on sensors before

attaching them to the pipe.

The f owmeter uses an even number

of passes. This is the most conveni-

ent mounting arrangement, as the

transducer separation distance can

be measured very easi y and the

sensors can be accurate y a igned.

Use whenever possib e (Pic. 3).

Signa trave s on an odd number of

passes through the pipe. A sing e

and for dirty/aerated iquids where

greater signa attenuation can occur.

The sensor distance on this moun-

ting configuration can be negative

(sensors over apping) (Pic. 4).

• Mount the transducers with the suggested spacing between the

sensor heads. This distance has been determined by the f ow-

meter on the basis of the entered parameters.

• Use the disp ayed number of passes to insta the sensors on the cor-

rect side of the pipe (see pictures 3 and 4).

• Observe the upper bar (signa -to-noise ratio) and ower bar (signa

qua ity). These shou d be both fi ed to about the same eve with a

fi ing eve of around 1/3 or more desired.

• Even number of passes: Both sensors on same side ofpipe (see pic. 3).

• Use the cursor between the two signa bars for fine adjustment

of the sensor position. With correct pipe parameters entered and

the sensors mounted at the suggested spacing, the mark shou d be

near the centra indication ine (see three ines be ow the bottom

signa bar).

• If the mark is to the eft-hand side of the centra indication ine, the

sensors are too c ose to each other. If the mark is to the right, the sen-

sors are too far apart. S ide one sensor carefu y a ong the pipe to

bring the mark into a more centra position. Measurements can be

obtained when the mark is between the eft and right indication

ine. Press

• When measuring, the f owmeter wi be ogging the PT100 input

and can be viewed by pressing

on the keypad.

• This data can a so be assigned to a process output in the

I /Output

menu fo owing the same process.

Process In/Ou pu s: Se up

• Configured in/outputs can be set up in

depending on which in/outputs are avai ab e. The in/output is-

ted at the top of the ist on

Slot 1

inside the connection compart-

ment, the in/output isted second from top on

Slot 2

and so on.

• After se ecting an in/output, it can be assigned to a measurement

channe . The structure of the further steps depends on the indivi-

dua type of in/output.

Process In/Ou pu s: Connec ion

• In/outputs can be connected to devices via screw termina s.

These can be found inside the connection compartment be ow

the contro pane .

• The i ustration on the eft gives an overview of the termina

assignment (Pic. 6).

• Remove the screws at the eft and right to gain access to the

compartment.

Hea Quan i y Measuremen (where specified)

• The KATf ow 150 is capab e of measuring heat f ow and heat quantity.

• To measure heat f ow, se ect a heat f ow unit (W, kW, MW) as

Middle

U it

when going through the

Setup Wizard

of the se ected measure-

ment channe .

• To measure heat quantity, se ect a heat quantity unit (J, kJ, kWh).

• On se ection of one of these units, the f owmeter requests the entry

of the specific heat capacity of the medium in [J/(g.K)]. Enter the

va ue of the f uid and confirm with

ENTER

. Comp ete the remaining

steps ofthe

Setup Wizard

• The temperatures at the in et and out et of the monitored system are

used to determine heat f ow and heat quantity.

• Connect the supp ied 4-wire PT100 temperature sensors to the f ow-

meter as per the i ustration be ow (Pic. 6).

6. Input/output compartment, inside termina s

• After setting up the f ow measurement channe go to

Mai Me u

, in order to assign the PT100 inputs to the channe .

• Use the cursor keys to se ect

and confirm with

ENTER

• On the next screen, use the cursor keys to se ect the f ow channe to

which the temperature input is app ied. Choose

wi disab e the input. Confirm with

ENTER

• On the fo owing screen choose

PT100

to use the temperature meas-

ured on the pipe. To enter a fixed temperature va ue, se ect

User

and

enter the va ue.

• Define whether the PT100 sensor measures the in et or out et tempera-

ture. Use the cursor keys to se ect as appropriate and confirm with

ENTER

• On the next screen a temperature offset can be app ied. After confirm-

ing again with
