1.1 Intended use
The magnetic inductive flow sensor MFS2 must only be used for measuring and metering
liquids with a minimum conductivity of 20 μS/cm.
WARNING! No safety component!
The magnetic inductive flow sensor of the series MFS2 are not safety components in
accordance with Directive 2006-42-EC (Machine Directive).
Never use the MFS2 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 being 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 MFS2 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 MFS2 is always completely filled ( § 4.1
Ensure that the conductivity of the fluid is at least 20 μS/cm.
1.2 Exclusion of liability
We accept no liability for any damage or malfunctions resulting from incorrect installation,
inappropriate use of the device or failure to follow the instructions in this operating manual.
