2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations apply­ing to Health & Safety and prevention of accidents.

When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.

as per 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

Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, as they are responsible for damages during transit.

Scope of delivery:

The standard delivery includes:

4. Regulation Use

The TUR series units are used for the flow measurement of liquids. These units
are furnished with the following outputs.

Pulse Output

Rotary motion of the turbine a signal with a specific frequency.

Analogue Output

In order to transduce the measured flow data, an analogue output is available,
(DIN IEC 381) with 0-20 mA, 4-20 mA or 0-10 V (see Type-tag).

Only low-viscosity media flows that are chemically compatible with the sensor
housing materials may be measured. With higher-viscosity media, considerable
measurement-errors will occur.

Long fibre-pieces may jam the rotor.

5. Operating Principle

The unit comprises a thick-walled plastic pipe; rotatable PVC flanges are secured
at each end.
At the meter inlet and outlet bearing supports help to reduce media turbulence. A
turbine-wheel with a core of moulded soft iron rotates as the liquid flows trough
the body.
The metallic parts are not exposed to the medium and are therefore protected
against corrosion. The bearings are made of sapphire and are self adjusting.
The bearings are made of chemically highly resistant Wolfram-carbide and are
moulded into the turbine wheel. The rotation is sensed through the built in pulse
transmitter, which requires no sealing and has now mechanical connection with
the turbine wheel. This rotation is converted into pulses by the associated
electronics.
The version with integrated transducer converts the frequency into a standard­analogue signal. An optionally available, external electronic unit processes the
pulse output-signal to drive a display, allows limit contact produces an analogue
output or indicate the measure of flowing volume.

6. Mechanical Connection

Before Installation:

 Please ensure that the actual flow-rate corresponds with the measured volume

within measuring range of the unit. Measuring range is printed on the type-tag.

Attention! Exceeding the measuring range (more than 20 %) may
result in damage to bearings and considerable measurement­errors.

 Make sure that the permitted max. pressure and temperature are not

exceeded during unit operation.

 Please ensure that the power supply of the unit corresponds with the power

requirements (operational data) printed on the Type-tag.

 Ensure that no packing material remains inside the unit.
 Mounting of these units is position-independent; the flow must always follow

the direction of arrow.

 During installation, please ensure that the pipe inlet straight is 4 times and

outlet straight is 2 times of nominal diameter of the unit.

 The installation is potential-free, and should be carried out with the help of soft

sealing rings or gaskets (not in the scope of delivery).

 If possible, just after mechanical installation, it should be checked that the

flange-connections are properly sealed.
