DUC-MF1 Quickstart

User Interface

DUC-MF1 will be switched on automatically after supply voltage has been plugged on.

Activates / deactivates the background lighting

To navigate through the different menus please use the keys located on the left and right beside the

display.

Move cursor in specific direction

Confirm your settings

Back to previous menu

XYZ Activates a certain function (depending on chosen menu)

Set-up your flow measurement in 5 steps

1. Choose suited mounting position for your transducers

2. Parameterize your flow transmitter

3. Mounting of ultrasonic transducers on your pipe

4. Set zero point (if possible)

5. Start your flow measurement

Pipe needs to be filled completely for clamp-on measurement

Parameterization and mounting

1. Switch on flow transmitter (automatically when plugging on supply voltage, see below)

2. Choose menu „quick setup“

3. Select diameter or circumference (depending on what figure you have) of your pipe

4. Put in value for diameter or circumference

5. Put in value for wall thickness of your pipe

6. Select pipe material

7. Select lining (if there is a lining)

8. Select type of ultrasonic transducer

Nr. 1 = DUC-WF-40 DN10…..DN100

Nr. 2 = DUC-WF-10 DN32…..DN400

Nr. 3 = DUC-WF-05 DN200…DN6000

9. Select method of mounting. Standard is V-mounting.

Confirm your settings and moves to next menu

Increase of values

Decrease of values

No function

10. Mount ultrasonic transducers on a pipe

After parameterization the display is showing the required distance between the two transducers in

mm and also as Index-No. Index-No. means the number of holes to be used for mounting with the

spacer bar. The first hole after the first transducers is hole No. 1, the last hole is the hole where

second transducer is put into the spacer bar (threaded bar). Picture 3 shows an example for an index-

No. 4.

Together with DUC-MF1 unit itself you will get one pair DUC-WF transducers and a spacer bar

which matches together with the delivered DUC-WF transducers.

If you have ordered more DUC-MF1 units and DUC-WF transducers for different pipe diameters

it could be that you get spacer bars with different length (short or long). Pls. see in the chart below

which spacer bar could be operated together with the corresponding transducer model.

Picture 1 spacer bar short (length 250mm, grid hole distance 7,5mm)

Picture 2 spacer bar„long“ (length 400mm, grid hole distance 15mm)

Picture 3 Example distance for bar index four using spacer Picture 4 example for distance in mm without

bar for mounting using spacer bar (V or W mode) face to face

11. Some acoustic coupling gel (app. size of a peanut, picture 5) or acoustic coupling foil has to be put at the part

which touches the pipe wall after installation (picture 6). Acoustic coupling foil is standard.

Long (40 cm)

12. Chose best location for DUC-WF transducer installation.

Straight run should be 10x diameter (inlet) and 3x diameter (outlet) in order to achieve best accuracy.

When using horizontal pipe, we recommend mounting the transducers at 10 o’clock or 2 o’clock

position to avoid any influence of gas bubbles / sedimentation might accumulated on top / on bottom

of pipe

Picture 6 Example Mounted Transducers with spacer

bar and mounted at app. 9 o`clock

13. The transducers are fixed to the pipe by using metal belts. The metal belts are tightened by using

tightener (picture in the middle). The length of the belt is designed for the biggest pipe size that the

transducer can cover. So for (significantly) smaller pipes it might be reasonable to shorten the belts

in order to make tightening easier. Please feed the belt into the tightener as shown in picture on

the left. Proceed in the same way for PT100. Put between PT100 and surface of the pipe also

acoustic coupling gel in between. After installation, PT100 should be insulated to minimize the

influence of ambient air temperature.

11 Set Zero Point (if possible)

If there is the chance to create „zero flow“ please select „Zero Setup“ and set zero point.

12. Go back to main menu and select button „MEAS“ . You enter the measuring

menu where you see the calculated flow, velocity,….

Change units:

->Go to main menu and select SETUP - > COMPL SETUP. Then select „UNITS SETUP“ to change units.

13. Activate Outputs

->Go to main menu and select SETUP - > COMPL SETUP. Then select “I/O-SETUP” and set digital and/or analogue outputs.

Please check DUC-MF1 user manual for further information. The user manual can be found as pdf-

document on the CD which is included in the delivery.

Wiring

To perform the wiring, it is necessary to remove the cable cover from DUC-MF1 by removing the two

screws (marked with red arrows, picture 8)

Power Supply

Please provide either 90-240 VAC or 18-36 VDC

(depending on chosen model). Please make

sure that you use the correct voltage.

Flow transmitter might be damaged when

using wrong supply.

Note: All in- and outputs (except relay) have defined potential on the

internal devices ground. For potential free operation of the in- and

outputs is additional hardware needed (with galvanic isolation). With the

normal in- and output it is not possible.

The instruction manuals on our website www.kobold.com are always for currently manufactured version of

our products. Due to technical changes, the instruction manuals available online may not always

correspond to the product version you have purchased. If you need an instruction manual that corresponds

Disposal

Note!

•Avoid environmental damage caused by media-contaminated parts

•Dispose of the device and packaging in an environmentally friendly manner

•Comply with applicable national and international disposal regulations and environmental

regulations.

Batteries

Batteries containing pollutants are marked with a sign consisting of a crossed-out garbage can and

the chemical symbol (Cd, Hg, Li or Pb) of the heavy metal that is decisive for the classification as

containing pollutants:

Cd1Hg2Pb3Li4

1. „Cd" stands for cadmium

2. „Hg" stands for mercury

3. „Pb" stands for lead

4. „Li" stands for lithium
