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: MIM
Operating Instructions
4. Regulation Use
The MIM 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: MIM, 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 MIM 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 MIM 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
μS / cm, the MIM 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 MIM. 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 MIM uses electrodes with galvanic tapping. They are in direct contact with the
medium. The standard electrodes are made of stainless steel 1.4404 (316 SS).

7. Mechanical connection
7.1 Check operating conditions
flow rate
max. operating pressure
max. operating temperature
In general, MIM is subjected to the same loads as the piping into which it is
installed. The MIM should therefore be kept away from extreme loads, such as
pressure surges with strong, dynamic pipe movements, vibrations in the proximity
of centrifugal pumps, high temperature media, flooding etc.
7.2 Installation
Remove all packing materials and transport retainers and ensure that no such
materials remain in the device.
It can be installed in vertical, horizontal or rising pipes. Flow in direction of the
arrow.
Avoid pressure and tensile load.
Mechanically secure the inlet and outlet pipe at a distance of 50 mm from the
connections.
Avoid valves or large reduction on the inlet section (this increases the
inaccuracy of measurements).
Check the leak tightness of the connections.
While mounting MIM hold the flowmeter from fitting surface (not
from the housing) with a wrench.
Take into account the tightening torque.
Nominal size Tightening torque
½“ 22 to 24 Nm
¾“ 28 to 30 Nm
1“ 28 to 30 Nm

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.
9.1.2 Function of the control buttons
The function of each control key can be recognized by the respective symbol
displayed in the corners of the TFT display.

9.2 Measuring mode
After applying the supply voltage, the device starts in measuring mode. In this
mode, the measured values of the respective measuring variables are continuously
recorded; the current instantaneous flow values, temperature values and the
volume counter readings are cyclically calculated and displayed according to the
type of display.
In addition to the main display, the states and configuration of the outputs are
shown in the display. If the corresponding output is configured as an alarm output,
the status is also displayed with a green or red background color. If the background
color is green, the set threshold value is exceeded; if it is red, the current value is
still under threshold.

The measured variables flow, temperature and volume counter can in principle be
assigned to each output function. The assignment of the respective output is
indicated by the display of the symbol of the measuring variable. The
representation of the assignment is independent of the set display layout (single,
dual).

9.2.1 Display area of the flow meters
The number of digits displayed on the volume counter display (partial and total
volumetric counters) is limited to max. 8 digits. The partial and total volumetric
meters therefore have a smaller font size than the flow and temperature display. If
the 8-digit display range of the meter is exceeded, this is indicated by the display
of 8 minus characters (--------). In this case, the meter reading can no longer be
read. The user now has the option of bringing the counter reading back into the
display area by changing the volume counter unit.

9.3 Menu Mode
In menu mode, all device parameters can be set. The individual parameters are
arranged in menu groups by function. While the menu mode is activated, the signal
processing and the outputs are still active in the background. However, all display
parameters and outputs are updated after exiting the menu mode or in the
measuring mode.
Note: The menu mode will exit automatically after a certain time without using the
buttons, if the parameter “Menu Timeout” is set not equal to “0”.
9.3.1 Parameter setting
9.3.1.1 List Selection
Parameters with predefined selection values are defined by means of list selection.
The currently selected menu item is displayed in orange text. The selection can be
moved with the keys, the key is used to accept the selection.
To activate the menu mode, press the button for 3-5 seconds. The parameters
are divided into main groups and subgroups.
The buttons are used to select the main groups. In the main menu not all
menu groups can be shown on the display at the same time, the list of individual
menu items then scrolls up or down when the selection has reached the top or
bottom. To choose the selection, the key is pressed and the device jumps to
the corresponding submenu or parameter setting level. For selecting of predefined
parameter values and are used. After changing the value of the parameter

9.3.1.2 Numerical value input
When setting parameters with a numerical value, the assigned unit is always
displayed below the input field in square brackets in the input function. The
maximum size and the number of decimal places are fixed and cannot be changed.
After calling the input function, first the left, outer digit is displayed in orange. This
position can now be adjusted either with the keys in the value from 0 to 9.
By pressing the key , the entry point moves to the right and the next digit can
be changed. By pressing the key , the editing point can be moved to the left
again. If the editing point is on the far right, the set value is saved by pressing the
key again and switched to the higher-level menu function.
10. Device configuration
10.1 Sequence of device parameterization
The flowmeter MIM is pre-configured in factory. Changing the parameters
"Measuring range" and "Sensor constant" or "K factor" is therefore not permitted.
The adjustment of these parameters is only possible on the part of Kobold-factory.
In the event of subsequent changes to volume or throughput units, the dependent
parameters are converted and adjusted accordingly. However, the limit parameters
of the switching outputs must always be checked and adjusted manually when
adjusting volume or throughput units - these are not automatically converted.
An accidental change of the parameterization can be revised by the function "Reset
factory setting" in the menu Userservice / Reset.

10.3 Display
10.3.1 Refresh
Parameter "Refresh" defines the time interval within which the measuring variables
are displayed. The "Refresh rate" can be increased in steps of 0.5 sec. to 10 sec.
An increase in the refresh rate time causes an increased "filtering" of the display
value.
10.3.2 Orientation
With the menu item "Orientation" the display can be rotated either clockwise or
counterclockwise in 90 ° increments. As the display rotates, both the display
contents and the function of the 4 control buttons are turned.
10.3.3 Layout
This parameter can be used to configure the display to either show one
measurement variable or two measurement variables.
10.3.4 Display value
With the aid of this parameter, the measurement variables provided by the
transmitter can be displayed. Depending on the 'Layout' display, either one or two
measuring variables can be displayed.
10.3.5 Keys HOTKEYs
Two independent user keys
are available, which can be
individually assigned with
different display functions.
The 2 user keys are available
in measurement mode top
right and left. If the buttons
are activated, they are backlit
in blue and the programmed
function can be executed by
touching.
The following functions are available:
reading MIN/MAX /
Reset
Value display /

MIM-
page 18 MIM 01/0419
The called hotkey function remains permanently activated and can only be left by
pressing the key . A direct reset function is available for the MIN / MAX measured
value function and the partial quantity counter.
10.3.6 Key sensitivity
The sensitivity of the keys can be adjusted by setting the key sensitivity. The default
setting "Low" is the optimal one when using the device with a finger. When operating
with gloves, it is essential to select the "High" setting.
10.3.7 Menu Timeout
The menu timeout time defines the time after which the menu function is automatically
exited without pressing a key. In the setting "0 s" this function is deactivated and the
menu function can only be left by hand by pressing the back key several times.

10.4.1 Flow
10.4.1.1 Unit
The displayed unit for the flow measurement can be selected from various
predefined standard units. It is also possible to define a user-defined unit ("user"),
here the "user unit" must be in LPM (liters / min.) be programmed:
e.g. Unit User = 100 LPM, if Q = 500 LPM then the display shows 5 users.
10.4.1.2 Separation
The parameter Separation sets the flow rate below which the measured value is
set to "0". If this function is active, the flow value "0" is shown in blue colour in the
display.
10.4.1.3 Simulation mode
See section 10.4.5
10.4.2 Volume
10.4.2.1 Counter type
Absolute:
Regardless of the flow direction, the calculated partial volume is added to the
counters.
Bidirectional:
Depending on the flow direction, the calculated partial volume is added or
subtracted to the counters. If the measured flow value is negative, the volume value
goes down from measurement to measurement (possibly into the negative range).
10.4.2.2 Unit of the total volume counter
The parameter "Unit" determines the volume unit of the total volume counter. The
listed volume units are available. When changing the volume unit, the current
counter reading is converted to the new volume unit.
