3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
Electromagnetic Flowmeter model: MIS
Operating Instructions
4. Regulation Use
The MIS flowmeter has been specially developed for the measurement, display
and transmission of both, flow rates and temperature of conductive liquids. The
instrument has a graphic TFT display, rotatable in 90 ° steps and can display flow
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
The MIS device with stainless steel housing and stainless steel electrodes is
weatherproof and conforms to protection class IP67. The meter is designed for
harsh indoor or outdoor environments and complies with Directive 2014/30/EU
(Electromagnetic Compatibility).

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. Mechanical connection
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.

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.

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.
