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 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.
Table 8, Pipe, Group 1 dangerous fluids
3.Instrument Inspection
These devices are checked 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, since they are responsible for damages
during transit.
Scope of delivery:
•Turbine-Wheel Flow Meter: Model DRS
•Operating Instructions
4. Regulation Use
The DRS is to be installed only in the specified applications. Any use of the DRS
sensor which exceeds the manufacturer’s specifications may invalidate the
warranty and any resulting damage is not the responsibility of the manufacturer.
The user assumes all risk for such usage. The application specifications include
the installation, start-up and service requirements specified by the manufacturer.

DRS

5.Operating Principle
The DRS flow meter operates on the turbine wheel principle. The liquid first flows
through a laminar flow element that eliminates turbulence and routes the flow
stream into the turbine wheel. The turbine wheel then starts to rotate. This rotary
motion is sensed non-contacting by magnets embedded in the turbine wheel and
converted to a frequency signal. The frequency is proportional to the flow
velocity. Various outputs, such as frequency divider, analog output or
compact electronics with LED display with limit contacts are available as
options. An integrated temperature sensor for simultaneous measuring of
flow rate and temperature is also available as an additional option. The
rotating vane is sapphire-supported: this ensures a high degree of linearity and
long service life.
6.Mechanical Connection
6.1.Operational conditions check-up:
•Flow volume
•max. operational pressure
•max. operational temperature
Attention! Exceeding prescribed ranges may cause damage to ball-
bearings and considerable measurement errors may result.
6.2.Mounting
•Installation can be in horizontal and vertical pipes (flow direction from bottom
to top). Flow in the direction of the arrow.
•Pressure and tensile loading is tobe avoided on the connection threads.
Inlet and outlet piping should be secured at least 50 mm away mechanically
from the connections.
•Check the sealing of the connections.
•The use of flat sealings isto be preferred. The sealing surfaces are shown in
section 11 - “Dimensions“

7.Electrical Connection
7.1.General
Attention! Ensure that the power ratings of your supply system are
in agreement with the power ratings of the flow meter.
•Please ensure that the electric supply lines are not active.
•Wire the connection cable/plug with the supply line according to the following
connection diagram.
•We recommend a cross-sectional area of 0.25 mm² for the supply line.
Attention! A false level on plug connections may cause destruction
of unit’s electronics.

8.1.Frequency output
The measuring units are pre-adjusted and readyfor operation after electrical
connection.
8.2.Analog output
The measuring units are pre-adjusted and ready for operation after electrical
connection.
8.3.Compact electronics
Please see
Operating Instruction Manual for compact electronics withfrequency output
9.Maintenance
As long as the medium to be measured is not polluted, the measuring unit is
maintenance-free. Inorder toavoid problems, we recommend installation of a
filter, such as magnet filter, Model MFR.
Should cleaning be deemed necessary, the sensor must be uninstalled and
rinsed thoroughly in clean water.
Work on electronics may only be carried out by the supplier, sothat the
product guarantee remains valid.
