Page 6: Intended Use
Intended use Magnetic inductive flow sensor DM08 is only intended to be used for measuring and dos - ing / batching the flow of electric conductive, liquid media According to the Pressure Equipment Directive 2014/68/EU, only Group 2 fluids are per - mitted to be used. -
Page 7: Safety Instruction
( "Characteristics of the DM08"). Take appropriate measures to ensure that the medium does not freeze. Only use the DM08 if it is in perfect condition. Damaged or faulty devices must be checked without delay and, if necessary, replaced. -
Page 8: Construction And Function
Construction and function Construction The DM08 comprises a sensor and the display electronics. The sensor is used to measure fluid media. The display electrodes generate the coil current required for the magnetic field and prepares the induced voltage applied to the electrodes. -
Page 9: Functions
The display electronics needs to be mounted separately from the sensor if: the mounting area is difficult to access or there is a lack of space, • medium and ambient temperatures are extremely high, • there is strong vibration. • DM08 Instruction manual 12/2018 page 9... -

Page 13: Sensor 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. - Page 14 If several sensors are installed in series, the distance between each sensor must • be equal to the length of one sensor. If two or more sensors are to be installed in parallel, the distance between sensors must be at least 1 m. DM08 Instruction manual 12/2018 page 14...

Page 15: Mounting
• Mounting As a compact device, the DM08 is installed directly into the pipeline. With the separate design, the sensor is installed in the pipeline. The display electronics can be attached to the wall with the bracket. -
Page 16: Electrical Connection
> De-energize the electrical system before connecting the DM08. Make the electrical connection of the DM08 through the terminal strips in the interior of the display electronics. For the separate design, the sensor cable for the electrodes and the magnetic current are required in addition. - Page 17 24 V : 30 V : 60 mA : 1.8 W Recommendation Pull-Up / Pull-Down resistance ~5 kΩ. Wiring current output (passive): An external voltage supply is required when connecting the passive current output. DM08 Instruction manual 12/2018 page 17...

The parameters of the DM08 can be changed in this operating mode. After entering the corresponding password, either only the customer-modifiable functions (customer pass- word) or all functions (service password) are released for modification.
- Page 21 This password can be changed when the device is first put into operation. Therefore changes should be kept in a safe place. The factory setting for the DM08 customer password is: "0002". The service password allows modification of all functions and parameters. This password is not given to customers.
