Instruction Manual

DM08

5.2.2  Cathodic protectives

Using a cathodic protective unit to avoid corrosion, which put a voltage to the tube wall, it must be 

connected to terminal FE. The boards, control panel and internal switches of the display electron-

ics are on the same potential as FE.

CAUTION! Electric current - comply with limits!

According to EN 61010-1:2012 all electrical circuits with „protective safety isolation without any 

protection against contacts” must observe the following maximum voltages: 

Maximum AC voltage (V

eff

)

33 V

Maximum DC voltage 

60 V.

 Make sure that no higher potential is connected to FE.

5.3

 Sensor installation instructions

CAUTION! Risk of malfunction due to external magnetic fields!

Magnetic fields close to the device can cause malfunctions and should be avoided.

 Ensure that no external magnetic fields are present at the installation site of the DM08.

Please observe § Delivery, unpacking and accessories "Delivery, unpacking and accessories" and 

the following installation instructions:

General:

The DM08 can always be installed at any point on the pipeline in the horizontal as well as in
vertical sections. 
Ideally, the sensor should be installed in a pipeline with a sufficient straight run, both before 
and after the measuring point. 

Technical changes reserved
