rate, temperature, daily volume counter (resettable) and total volume counter in
the units of measurement selected by the operator. A clear menu guides the user
through the parameterization of the device, which largely eliminates the need to
look into the operating instructions.
Any use of the magnetic flowmeter, model: MIS, which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.
5. Environment

6. Operating principle
6.1 General
The new KOBOLD MIS Flowmeter is designed to measure and monitor small and
medium flows of conductive fluids in piping.
The device works on the magnetic-inductive measuring principle. According to
Faraday's law of induction, a voltage is induced in a conductor moving in a
magnetic field. The electrically conductive measuring medium corresponds to the
moving conductor in the process. The voltage induced by the measuring medium
is proportional to the flow rate and thus a measure of the volume throughput.
Prerequisite is a minimum electrical conductivity of the flowing medium. The
induced voltage is fed to a measuring amplifier via two electrodes, which are in
conductive contact with the medium. The volume flow is calculated via the
defined pipe diameter.
The measurement is independent of the medium and its physical properties such
as density, viscosity and temperature. The device can be configured via the
display. There are two outputs available, which can each be configured as alarm,
frequency, pulse, voltage, and current outputs.
The device also provides a dosing function. The dosing function can be activated
in measuring mode via the four buttons. The dosing function controls simple filling
tasks and also measures flow rate and partial amount.
6.2 Minimum electrical conductivity / Gas bubbles
For the correct function of the instrument, it is necessary that the flow channel is
always completely filled with medium. From a minimum electrical conductivity of
20 S / cm, the MIS operates within the specified error limits. The conductivity of
the medium is constantly monitored by the device electronics. If the electronics
detects that the minimum conductivity has fallen below min. value, this is signaled
by displaying the error message 'Empty pipe' and the flow rate reading is set to
'0'. Air bubbles in the flowing medium or media with varying conductivity in the
range of the minimum conductivity can disturb the measuring function and reduce
the measuring accuracy of the MIS. Gases contained in the liquid are also
measured as a flow volume and lead to measurement errors. If necessary, install
appropriate vents in the flow of the unit.
6.3 Deposits
Minor deposits on the measuring tube generally do not affect the measuring
accuracy unless their conductivity deviates significantly from the liquid. For liquids
that have a tendency to deposit, periodically inspect the meter tube and, if
necessary, clean it.
6.4 Measuring electrodes
The MIS uses electrodes with galvanic tapping. They are in direct contact with the
medium. The standard electrodes are made of Hastelloy.

7.1 Receipt of goods and transport
7.1.1 Receipt of goods
 Check the packaging and contents for damage.
 Inspect the supplied goods to ensure complete delivery and compare the
consignment with your order specifications.
7.1.2 Transport
Please observe the following tips when unpacking your device, or transporting it to
its measuring point:
If possible the devices should be forwarded in the packaging in which they
were delivered.
Do not remove any protection disks or caps from the process connections.
This is particularly important in the case of sensors with a PTFE flow tube
lining. The protection caps should only be removed immediately before
installation of the device in the pipe.
Never lift the devices by the mounted transmitter housing or terminal box
for transport. When transporting heavy devices, use slings. Place these
around both process connections. Do not use chains as these can damage
the surface coating and the housing.
When transporting devices without lugs, and when looping the slings
around the flow tube, the center of gravity of the entire device can be higher
than both attachment points of the slings. When transporting the device
ensure that it does not rotate or slip accidentally. This could cause injury.
Sensors with a nominal size of more than DN 150 should not be lifted by
the sheet metal of the shell with a forklift truck. This could dent the sheet
metal of the shell and damage the internal solenoid coils. There is also the
risk that the device could roll off the forks.
If the sensor is provided with PTFE (Teflon) lining, then, upon delivery, the
sensor is mounted with two wooden discs, to hold the lining in position
during transport and storage. These wooden discs should remain on the
sensor until installed. Without the discs, the liner creeps back to its original
shape and installation is more difficult to do. The sensor should be left for at
most a few hours without the discs. Remove the discs immediately before
installation.

MIS K01/0719 page 9
7.2 Installation requirements
The installation location in the pipe must be selected so that the sensor is always
fully filled with the fluid and cannot run empty. This can best be guaranteed if it is
installed in an ascending pipe or drain.
The measuring principle is generally independent of the flow profile of the fluid
provided no standing vortices reach into the area of measurement, such as from
elbows or half-open sliding valves upstream from the sensor. In these cases
measures must be taken to normalize the flow profile. Practical experience has
shown that in most cases a straight inlet section of ≥5 x DN and an outlet
section of ≥ 2 x DN of the nominal sizes of the sensor is sufficient. The
occurrence of strong electromagnetic fields in the vicinity of the installed sensor
must be avoided.
For the Implementation of forward and backward flow measurements, both sides
of the sensor must be provided with a straight pipe section with the nominal sizes
of the sensor and a length of 5 DN of the nominal sizes of the sensor. It is
advisable to install actuators, such as regulating or shut-off devices, downstream
from the sensor. The forward flow direction is marked on the sensor with an arrow.
When mounting sensors, always observe the specified screw torques.
After the installation of the sensor and the electrical connections between the
sensor and the transmitter has been made, the system can be taken into
operation. To prevent measuring errors caused by gas pockets in the fluid and
damage to the lining of the sensor caused by negative pressure, the following
points must be observed:
7.2.1 Bypass pipes
To allow for a problem-free dismount, emptying and cleaning of the sensor, a
bypass pipe may be installed. The bypass with a blind flange permits the fluid pipe
to be cleaned without having to dismount the flowmeter.
This is recommended for
highly soiled fluids.
7.2.2 Sensor tube lining
If the flow tube is lined with PTFE, the flowmeter must be installed with special
care. The tube lining is
bordered at the flanges (seal). This must not be damaged
or removed as it prevents the fluid from penetrating between the flange and flow
tube destroying the electrode insulation.

MIS
page 10 MIS K01/0719
7.3 Installation
Screws, bolts, nuts and seals are not in the scope of delivery and must therefore
be provided by the operator. The sensor is to be installed between the pipes.
Please observe the required torques stated Section “Torques for screws and
bolts”. The installation of additional grounding rings is described in Section
“Earthing – potential equalisation”. Use for the flanges only gaskets in accordance
with DIN EN 1514-1. Mounted gaskets must not reach into the pipe cross-section.
Caution!
Do not use conductive sealing compounds such as graphite. This could result in a
conductive layer building up on the inside of the flow tube, short-circuiting the
measuring signal.

MIS
MIS K01/0719 page 11
7.3.1 Installation in pipelines with larger nominal sizes
The flowmeter can also be installed in pipes with larger nominal sizes by using
pipe tapers (e.g. flange transition pieces in accordance with DIN EN 545).
However, the resulting pressure loss must be taken into consideration. To avoid
flow interruptions in the flow tube, a reducing angle of 8° for the tapers should
be exceeded.
7.3.2 Horizontal or vertical Installation
The installed position of the flowmeter is arbitrary, however the intended x-y
electrode axis should run approximately horizontal. A vertical Electrode axis
should be avoided, since gas pockets or solid particles carried along in the fluid
could affect the accuracy of the device.

7.3.3 Installation examples
To avoid measuring errors evoked by gas pockets or lining damage caused by
negative pressure, the following points must be observed:
Vibrations
To eliminate the effects of vibrations and prevent premature damage to the
transmitter, the sensor shall be supported in the near vicinity of the flanges.

Horizontal pipeline routing
Install preferably in slightly ascending pipes.
Open inlet or outlet
Where possible, the device should be installed in a syphon. The empty pipe
detection circuit of the
transmitter is an additional safety feature for recognizing
empty or partially filled pipes.
Caution! There is the danger of accumulation of solids in the siphon. The
installation of a cleaning aperture
in the pipe is therefore advisable.

MIS
MIS K01/0719 page 13
Down pipes
Where down pipes are to be found in the pipe system, a syphon or a ventilation
valve should be placed after the sensor. By these means, negative pressure can
be avoided in the pipeline, which may otherwise damage the sensor lining. This
measure will also prevent a breakdown of the flow reducing the risk of air
inclusions in the measurement medium.
Long pipelines
In long pipelines there is always a danger of pressure surges. Therefore
regulating and shut-off devices should be placed behind the sensor. However,
when installed in vertical piping, especially when using sensors with PTFE-lining
and high operating temperatures, the regulating and shut-off devices should be
placed in front of the sensor (danger of vacuum).

MIS
page 14 MIS K01/0719
Installation of pumps
To avoid negative pressure and eventual damage to the tube lining, never install
flowmeters on the suction side of pumps.
If necessary, arrange for pulsation dampeners when using piston, diaphragm or
hose pumps.
Consider the space requirements beforehand with respect to a potential
deinstallation of the device.
7.3.4 Earthing – potential equalisation
The sound grounding concept of the flowmeter is a necessity for both safety
reasons as well as to ensure a faultless operation. In accordance with VDE
0100 Part 410 and VDE 0100 Part 540 the grounding connections must be at
protective conductor potential. For metrological reasons, this potential must be
identical to the potential of the fluid. The grounding cable should not transmit
any interference voltage. For this reason do not simultaneously ground other
electrical devices with this cable.
The measuring signal tapped at the electrodes amounts to only a few millivolts.
Correct grounding of the electromagnetic flowmeter is therefore an important
prerequisite for exact measurement. The transmitter
requires a reference
potential to evaluate the measured voltage on the electrodes. In the simplest case
the
non-insulated metal pipe and/or the connecting flange may be used as a
reference potential.
Where pipes are lined with electrically insulating materials or pipes are made of
plastic, the reference potential can be obtained from a grounding ring or
grounding electrode. These establish the necessary conductive connection to the
fluid and are made of a chemical-resistant material. The material used should be
identical to that of the measuring electrodes

MIS
MIS K01/0719 page 15
7.3.5 Earthing with earthing electrodes
The device can be optionally equipped with grounding electrodes. With plastic
pipes this version is the easiest grounding method. As the surface of the
grounding electrode is relatively small, the use of grounding rings on both sides
of the sensor is preferable in systems in which high equalizing currents along the
pipeline can be expected to occur.
7.3.6 Earthing with earthing rings
The outside diameter of the grounding ring should be at least equal to the
diameter of the flange or be dimensioned in such a way that the grounding ring
is positioned inside the flange bolts and is centered by these. The terminal lugs
routed to the outside must be connected to the FE terminal in the junction box of
the sensor. During installation ensure that the inner diameter of the seals do
not protrude over the grounding disk!
The grounding cables are not included in the scope of your delivery and
must be provided by the plant operator.
The grounding rings can be ordered as accessories.

7.3.7 Torques for screws and bolts
Due to the fact that the flow pipe lining is made of plastic or vulcanized materials
such as hard rubber. Or PTFE, electromagnetic flowmeters must be installed in
pipe system with special care since these materials are malleable under pressure.
If the flange screws are overtightened, the sealing surface will deform. If the seals
are to function properly, the correct torque is highly important.
Tighten the screws crosswise so that the process connections are tight. When
tightening the screws for the first time approx. 50 percent of the required torque
should be reached, for the second time the torque should be 80 percent. The
required torque should reach 100 percent when the screws are tightened for the
third time. For higher torques it is advisable to use protectors.
The maximum permissible torques can be obtained from the following table

9. Operation and menu structure
9.1 General
9.1.1 Operation of the optical buttons
An optical button is located at each corner of the TFT display. The operability of
the respective buttons is signaled by blue backlighting; therefore non-backlit
buttons are disabled and cannot be operated. To operate the keys, the finger
must be placed on the key-dome and raised again. The orange background of the
button symbols is briefly displayed in blue as visual feedback for a detected key
press.
To avoid accidental operation in measuring mode, the operator must hold down
the menu button for 3-5 seconds to activate the function. If the menu button is
held down for more than 3 seconds, the blue backlighting will begin to flash to
alert the user to release the button.
The operation of the optical buttons can also be done with gloves or other
optically reflective objects, light dirt on the surface usually does not interfere with
the key function.
