Instruction Manual
DM08
2.2
Intended use
Magnetic inductive flow sensor DM08 is only intended to be used for measuring and dosing /
batching the flow of electric conductive, liquid media
According to the Pressure Equipment Directive 2014/68/EU, only Group 2 fluids are permitted to
be used.
Due to the magnetic field, the device can be used to measure flow rates up to 10 m/s (32.8 ft/s) and
a minimum conductivity of 50 μS/cm, when using a synchronized static field.
WARNING! No safety component!
The flow sensor of the series DM08 is not a safety component in accordance with Directive
2006/42/EC (Machine Directive).
Never use the DM08 as a safety component.
The operational safety of the device supplied is only guaranteed by intended use. The specified
limits (§ Sensor installation instructions "Sensor installation instructions") may under no circum-
stances be exceeded.
Before installing the device, check if the wetted materials of the device are compatible with the me-
dia being used (§ Materials "Materials").
CAUTION! Risk of injury due to high temperature!
Hot process media can lead to hot surfaces! Danger of burns with surface temperatures above 70
°C.
Take suitable protective measures, e.g. contact protection.
The contact protection must be devised so that the maximum ambient temperature on the
device is not exceeded.
Flow tube empty (partially filled). / Conductivity too low:
Faulty measurements can occur if the flow tube of the DM08 is empty or partially filled or if the
conductivity of the fluid being used is too low.
Make sure that the flow tube of the DM08 is always completely filled (§ Sensor
"Sensor").
Please observe the function "Empty pipe detection" (p. 11).
Make sure that the fluid being used has a conductivity of at least 50 μS/cm.
Before ordering and installing, check that the device is suitable for your application.
2.3
Exclusion of liability
We accept no liability for any damage or malfunctions resulting from incorrect installation, in-appro-
priate use of the device or failure to follow the instructions in this operating manual.
