Instruction Manual
DM04
IMPORTANT!
Use the type plate to check if the delivered unit corresponds to your order.
In particular, for devices with electrical components, check to see if the correct power sup-
ply voltage is specified.
Accessories:
Connection cable with moulded M12x1 coupling socket.
M12x1 coupling socket as component.
1.2 Intended use
The magnetic inductive flow sensor DM04 must only be used for measuring and metering liquids with a
minimum conductivity of 50 μS/cm.
WARNING! No safety component!
The magnetic inductive flow sensor of the series DM04 is not safety components in accordance with
Directive 2006-42-EC (Machine Directive).
Never use the DM04 as a safety component.
The operational safety of the device supplied is only guaranteed by intended use. The specified limits
(§ 9 “Technical data”) may under no circumstances be exceeded.
Before installing the device, check that the wetted materials of the device are compatible with the media be-
ing used (§ 9.2 “Materials table”).
Measuring tube empty (or partially filled). / Conductivity too low.
The green LED may blink irregularly if the measuring tube of the DM04 is empty or partially filled
or if the conductivity of the fluid being used is too low. Random pulses will be present at the output,
but they do not represent an actual flow.
Ensure that the measuring tube of the DM04 is always completely filled (§ 4.1 "Installation
instructions").
Ensure that the conductivity of the fluid is at least 50 μS/cm.
1.3 Exclusion of liability
We accept no liability for any damage or malfunctions resulting from incorrect installation, in-appropriate
use of the device or failure to follow the instructions in this operating manual.
