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, since they are responsible for damages during

transit.

Scope of delivery:

The standard delivery includes:

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.
