4. Regulation Use
Any use of the Low volume rotating vane flowmeter, model: DTK”, which exceeds
the manufacturer’s 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 Principle
The medium flows through a specially shaped flow housing and causes a vane to
rotate. The vane has imbedded permanent magnets. Which are detected by a
Hall Effect sensor as they pass. The Hall Effect sensor generates a voltage pulse
each time a magnet passes. The frequency of the pulses is directly proportional
to the flow velocity.

6. Mechanical Connection
Before installation:
 Remove all transport packaging and ascertain that no packaging material is
left in the instrument
 Please ascertain whether the allowable maximum operating pressure and
operating temperature of the instruments will not be exceeded (see standard
material combinations).
 Please ascertain after completing of mechanical installation, whether the
connection between fitting and pipe is tight.
Warning! Overflows of more than 20 % might damage the bearings
and cause larger measuring errors or malfunction.
