Intended use
The magnetic inductive flow sensor VMI must only be used for measuring and metering liq-
uids with a minimum conductivity of 50 μS/cm.
WARNING
The magnetic inductive flow sensors of the VMI series are no safety components in
accordance with Directive 2006/42/EC (Machine Directive).
 Never use the device as a safety component.
The operational safety of the device supplied is only guaranteed by intended use. The speci-
fied limits ( § 9 "Technical data") may under no circumstances be exceeded.
Before installation, check whether the wetted materials of the device are suitable for the liquid
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 VMI 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 VMI is always completely filled
( § 4.1 "Installation instructions").
 Ensure that the conductivity of the fluid is at least 50 μS/cm.
