2. Note

Please read and take note of these operating instructions before unpacking and

putting the unit in operation, and follow the instructions precisely as described

herein.

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 to the

purchased product version, you can request it from us free of charge by email

([email protected]) in PDF format, specifying the relevant invoice number and

serial number. If you wish, the operating instructions can also be sent to you by

post in paper form against an applicable postage fee.

Operating instructions, data sheet, approvals and further information via the QR

code on the device or via www.kobold.com

The devices are only to be used, maintained and serviced by persons familiar

with these operating instructions and with the prevailing regulation applying to

procedural safety and the prevention of accidents.

When used in machines, the measuring unit should be used only then when the

machines fulfil the EC-machine guide lines.

PED 2014/68/EU

In acc. with Article 4, Paragraph (3), "Sound Engineering Practice", of the

PED 2014/68/EU no CE mark.

3. Instrument Inspection

These devices are checked before dispatch and shipped in perfect condition.

Should damage to a device be visible, we recommend a thorough inspection of

the delivery packaging. In case of signs of damage to the packaging, please

inform your parcel service/forwarding agent immediately, since they are

responsible for damages during transit.

Scope of delivery:

 Low Volume Rotating Vane Flow Meter model: DPM

4. Regulation Use

Any use of the Rotating Vane Flow Meter, model DPM, which exceeds the

manufacturers specification may invalidate its warranty. Therefore, any resulting

damage is not the responsibility of the manufacturer. The user assumes all risk

for such usage.

5. Operating Principles

KOBOLD model DPM flow meters are used for measuring and monitoring liquids.

Due to its compact construction the measuring instrument is suitable for use with

machines with minimum available space. The system can be used in a wide

variety of applications because the output pulses can be analysed in many

different ways.

The medium flows though a specially shaped housing nozzle and causes a vane

to rotate. This rotary motion is sensed by optoelectronics in a non-contacting

manner, and converted to a pulse frequency signal or an analogue signal. A

frequency divider with pulse output is available as an option. The frequency is

proportional to the flow velocity. The vane is sapphire-supported, this ensures a

high degree of linearity and long service life.

6. Mechanical Connection

6.1. Check service conditions:

 flow

 max. operating pressures

 max. service temperature

Attention! Overrange can cause damage to bearings and major

measuring errors

6.2. Installation

 flow in direction of arrow (universal)

 avoid pressure and tensile loads, mechanically fix inlet and outlet lines at

distances of 50 mm from the connections

 check connections for leaks

7. Electrical Connection

7.1. General

Attention! Make sure that the voltages in your plant correspond with

the flow meter voltages.

 Make sure that the electrical supply lines are dead.

 We recommend a power supply cable with cross sectional area of 0.25 mm².

Attention! The instrument electronics may be damaged if the cable

connections are wired incorrectly.

7.5. Cable outlet with M12x1 angle plug electronic options F3x

and L3x

When using a pre-assembled M12x1 connection cable with angled plug, the

cable outlet is always aligned opposite to the flow direction.

8.1. Frequency output

The measuring instruments are ready for operation after electrical connection.

8.2. Analogue output

The measuring instruments are ready for operation after electrical connection.

8.3. Compact electronics

The measuring instruments are factory programmed and ready for operation after

electrical connection.

(To change the settings, see Operating Instructions supplement for compact

electronics with frequency output)

9. Maintenance

The measuring instrument requires no maintenance if the measured medium is

clean. To prevent coating the sensor optics, we recommend that a filter is

installed, for example the magnetic filter, model MFR.

If the sensor has to be cleaned, then it can be opened to gain access to the

inside parts. Make sure that the sensor and especially the blades are not

damaged. When re-assembling, make sure that the vane is positioned and

oriented correctly.

Work on the sensor and electronics should only be carried out by the supplier,

otherwise the guarantee is nullified.

13. 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:

Cd1 Hg2 Pb3 Li4

1. „Cd" stands for cadmium

2. „Hg" stands for mercury

3. „Pb" stands for lead

4. „Li" stands for lithium
