Product name
Sensor type HPC
Transmitter type UMC4, suitable for use with Heinrichs Messtechnik Coriolis
mass-flow sensors
Version no.
1.0, dated January 31, 2019
2. Maintenance
2.1 Transmitter
The transmitter is maintenance-free.
We recommend cleaning the sight-glass in regular intervals; check the enclosure for corrosion damages
and the solid seat of the cable glands.
2.2 Coriolis mass flow sensor
The sensor is generally maintenance-free. The function only is influenced by corrosion or by deposits
inside the inside of the measuring pipes. Therefore both have to be avoided mandatorily. Deposits have
to be removed by suitably washing up or cleaning the internal pipes and splitter. Otherwise the measuring
precision cannot be obtained.
Danger
In the case of a loop breakage, e. g. due to corrosion, medium leaks, fills the enclosure. Medium can get into the mounted transmitter or terminal box also (particularly at
high process pressures)!
The transmitter can stand under pressure, too.
Take care if there are:
Visible discolourations or humidity condensation at the sight-glass of the transmitter,
corrosion damages to the enclosure,
deformation of the sensor enclosure.

4. The HPC sensor
4.1 Application domain of the HPC sensor
The HPC sensor is intended for use solely for direct and continuous mass flow measurement of liquids
and gases, irrespective of their conductivity, density, temperature, pressure, or viscosity. The sensor is
also intended for use for the direct and continuous mass flow measurement of chemical fluids, suspensions, molasses, paint, varnish, lacquer, pastes and similar materials.
4.2 Mode of operation
4.2.1 Measuring principle
The Coriolis mass flow meter is based on the
principle whereby in a rotating system a force
(known as the Coriolis force) is exerted on a
mass at a rotation point that is moving towards
or away from this point.
4.2.2 System configuration
The flow meter consists of a sensor that is
mounted in a pipe, and a transmitter (see Section 6 Application domain of the UMC4 on pp. 27), that
can be directly mounted on the sensor or installed separately (e.g. on a wall).
The transmitter oscillates the flow tubes in the sensor over a excitation coil and picks up, via the sensor coil, the measuring signal which is proportional to the mass flow. After being temperature compensated, the measuring signal is converted into an analog output signal that is consistent with the measuring range setting.
4.2.3 Measured variables
Measured variables: mass flow, density, temperature;
Calculated: Volume flow is calculated from the mass-flow and density

4.4.3 Pressure surges
Pressure surges in a pipe could be provoked by a sudden decrease in flow caused by rapid closing of
a valve or similar factors. This change in pressure can lead to negative pressure downstream from a
valve that has been closed rapidly, and to outgassing. If the valve is mounted directly on the inlet section of the flow meter, a gas bubble can form in the flow tube that can cause a measuring signal disturbance which would shift the zero point of the output signal. In extreme cases, a pressure surge
could cause mechanical damage to the sensors and/or flow tubes.
Whenever possible, quick-closing valves should be mounted downstream from the sensor. If this is not
feasible, such valves are to be mounted a minimum of 10 x DIA (Φ) from the nearest sensor. Alternatively, valve closing speed can be reduced.
Page 20 of 105
OPERATING MANUAL HPC & UMC4
4.4.4 Using the device with hazardous fluids
The sealing technology used in the standard HPC mass flow meter renders the device unsuitable for
use with hazardous fluids. Only sensors that meet the standards for safety instruments are suitable for
use with hazardous fluids.
The pathway between the sensor and transmitter must be pressure-tight so as to prevent fluid from
leaking out of a sensor in the event a sensor develops a defect.
In the case of welded components, a colored liquid penetration test may be performed on the welds, or
one joint (only the foremost seam) may be x-rayed. Alternatively, an internal pressure monitoring device can be used to detect any defect.
4.4.5 Vibration stability
The sensors are insensitive to vibration; vibration stability has been validated in accordance with
DIN IEC 68-2-6, for up to 1 g at 10 to 150 Hz.
If pipe vibration is greater than 1 g in the 5-2000 Hz range, additional mounting supports are to be
installed as shown in the following drawing. These supports will prevent vibration from affecting the
device’s mechanical configuration and/or measurement readings.

The above example represents a pipeline installation. The table and wall variant, with their accessories, are not affected by the representation.

4.5.3 Viscosity
0.3 to 2,000 mPas (0.3 to 2,000 cP)
4.5.4 Gas content
The use of products containing gas will increase the measurement error. To have any chance of
achieving an acceptable measurement of a gaseous liquid, it is essential that the gas bubbles are as
small as possible and that they are homogeneously distributed in the fluid. Large gas bubbles will provoke grave measurement errors, and may also shift the zero point. Thus, the process conditions
gravely influence the measurement accuracy of the meter. With this in mind, a rule of thumb is: 1 %
gas component will increase false readings by 1 %. The gas component to exceed 5 %.
4.5.5 Process temperature range
+ 180 °C (356 °F)
4.5.6 Process pressure range
According to PN100 pressure rating = 100 bar / PN 320 320bar / PN400 = 400 bar
4.5.7 Outlet pressure
Outlet pressure must be greater than the vapor pressure ps of the measured product.
4.6 Connection to the transmitter
In consideration of its small dimensions, the transmitter cannot be mounted directly onto the
HPC sensor.
The connection to the sensor is achieved by means of a detachable cable connector.
During installation, regulations and applicable legal standards are to be adhered to.
The maximum cable length is 300 m (1000ft). See Section 12.5.1.2 “Connection of the sensor” on
page 37 for information regarding the connection and cable specifications.

5. Commissioning
5.1 Zero point calibration
In order to ensure that precise measurements are obtained, zero point calibration is to be Performed the
first time the device is put into operation and before any regular operations are carried out. Zero point
calibration is to be performed using a fluid.
The zero calibration procedure is as follows:
Install the sensor as described in the manufacturer’s instructions.
Check to ensure that the sensor is completely filled with fluid and that there are no gas bub-
bles in the flow tubes.
Define the process conditions such as pressure, temperature and density.
Close a potential shut-off device behind the sensor.
Operate the transmitter in accordance with the instructions in Section 14.4.4 Zero point cal-
ibration on page 57.
Make sure that sufficient time is allowed for the electronics to warm up.
Allowing fluid to flow through the sensor during the zero calibration procedure will skew the
zero point and result in false readings, especially during low flow conditions.
5.2 Startup conditions
The device is not subject to specific startup conditions. However, pressure surges should be avoided.
OPERATING MANUAL HPC & UMC4
Page 27 of 105
Warning
Only sensors and transmitters marked as Ex-proofed on their rating plates may be
used in Ex hazardous areas!
Standard equipment is prohibited for use in Ex hazardous areas.
6. Application domain of the UMC4 transmitter
The microprocessor controlled UMC4 transmitter (hereinafter referred to as UMC4) for use with TM, TME
TMR, TMU and HPC sensors is a programmable transmitter which processes measurement data and
displays and transmits various types of measurement results.
The UMC4 is capable of communication and supports the HART® protocol. The device can be customized using the standard installed control unit BE4. Although basic configuration settings such as transmitter calibration are carried out at the factory, other settings such as those for measurement data processing, analysis, display and output are user definable.
User settings are protected by a user definable password. The user password can be changed by the
customer.
Settings that are essential for proper operation of the transmitter in conjunction with the sensor (e.g. calibration and initialization values) are accessible only to service technicians via a password that is not provided to customers.
7. UMC4 transmitter: mode of operation and configuration
7.1 Measuring principle
The Coriolis mass flow meter is based on the principle that in a rotating system a force (known as Coriolis
force) is exerted on a mass at a rotation point that is moving towards or away from this point. By configuring the sensor in a specific fashion, this force can be used to measure mass flow directly. The UMC4
transmitter evaluates the sensor signal (see Section 4.2.1 Measuring principle on page 14).
7.2 System configuration
Transmitter:
The UMC4 transmitter regulates the excitation of the sensor vibration system and processes the sensor
signals. The standard model is equipped with two analog, passive 4 to 20 mA outputs, an impulse or frequency output and a status output, and is enabled for digital data transfer via the HART® protocol.
Sensor:
The sensors measure mass-flow, density and temperature of fluids or gases. The device can be used to
perform measurements with any liquid or gaseous product providing that the sensor material is suitable
for the product being used.
Page 28 of 105
OPERATING MANUAL HPC & UMC4
Warning
Make sure that you abide by the applicable standards and regulations pertaining to electrical devices, device installation and process technology when replacing the transmitter electronics. The highly integrated electronic components
in the device carry the risk of ESD hazards and are only protected when installed in the device pursuant to EMC standards.
7.2.1 DSB data memory module
The replaceable plug and play memory device is integrated on the PCB of the control unit where all sensor data such as sensor constants, model numbers, serial numbers, and so on are stored. Consequently,
the memory module is linked to the sensor. If the transmitter’s electronics are exchanged for any reason,
the control unit BE4 must be removed from the old and placed onto the new electronic stack.
The removal and insertion of the control unit is performed as can be seen in the following sketch.
After removing 4 screws, the control unit with the display can be detached.
If the transmitter is replaced, the control unit should be transferred to the new transmitters electronic
stack. When the flow meter is powered up, the device continues using the values stored in the memory
device. Thus, the DSB memory device provides maximum safety and comfort when device components
are replaced.
The control units are not interchangeable arbitrarily between identically constructed transmitters
due to the memory device. Replaceable circuit boards must be ordered from Heinrichs using the trans-
mitter’s serial number specification. The calibration data of the sensor are programmed into the delivered
BE4 control panel directly by the manufacturer.

The low flow cutoff can be set to values between 0 and 20% using the software. The set value refers to
the upper-range value. If the measured value is lower than the set volume, the flow rate will set to 0.0
(kg/h). This results in the analog output being set to 0/4 mA, and the pulse output will stop generating
pulses.

Warning:
Additional cable glands:
They are not contained in the scope of supply. The operator is responsible
for guaranteeing that cable glands or screws according to the enclosures
certification are used. The type of thread present is stated on the rating
plate.
For the connection between sensor and transmitter a metalized cable gland
must be used for the screen.
(See 12.5.1.2 “Connection of the sensor” page 37)
Danger:
It is the customer’s responsibility to ensure the NPT adapters are mounted

sufficiently, water may leak into the terminal compartment of the enclosure.
Danger:
Particular care must be taken if the enclosure’s window becomes fogged or
discolored. This could mean that moisture, water or product is seeping through
the wire sheath into the transmitter’s housing.
11. UMC4 operating conditions
11.1 Installation conditions and cable glands
When mounting the UMC4 transmitter, a vibration-free installation site must be guaranteed.

12.5.2 The output signals
The output signals of the UMC4 are available in various Ex protection classes. The terminal designations vary depending on the protection class ordered.
The terminal designation and their protection class can be taken from the following table:
12.5.3 HART®
A number of options are available for HART® communication. However, for all these options loop resistance must be less than the maximum load specified in Section 9.3 Load (on page 30). The HART®
interface is connected via terminal 11 and 12 or 41 and 42 with a minimum load impedance of 250 Ω.
For information regarding operation of the transmitter using the HART hand-held terminal, see “Operation of the UMC4 transmitter using the HART hand-held terminal.”
12.5.4 Communication via Siemens PDM®
PDM® is the configuration software of Siemens that is used to operate HART® or Profibus PA compatible devices.
To connect a desktop or laptop computer to the UMC4, a HART® interface is required in addition to
communication software such as PDM. The HART® interface, which has two connections, converts the
levels of the RS 232 interface or USB interface into an FSK signal (frequency-shift keying).

13. Control unit BE4
13.1 Introduction
The UMC4 transmitter can be operated using control unit BE4, a desktop or laptop computer in conjunction with PDM® software, or via HART® Communicator.
In the following, transmitter operation and parameterization are described using control unit BE4 integrated into the electronic compartment. To use the control unit the cover window glass must be removed.
In Ex hazardous area, all relevant safety regulations have to be observed before opening the
window glass.
Control unit BE 4
13.2 Display
Control unit BE4 in the UMC4 has an integrated alphanumeric display with two 16-character lines
(format 15 x 52 mm). To improve the readability of the display at low ambient brightness, it is equipped
with a backlight. Measurement data and settings can be read directly from this display.
The LCD display is designed for operation at temperatures ranging from − 20 °C to + 60 °C (-4° F to
140 °F) without incurring any damage. However, at freezing or near-freezing temperatures, the display
becomes slow and readability of the measured values is reduced. At temperatures below − 10 C°
(14 °F), only static values (parameter settings) can be displayed. At temperatures exceeding 60 C°
(140 °F), contrast decreases substantially. When submitted to higher temperatures for long periods of
time, the liquid crystals may dry out.

Note:
Setting of “special 1” to “special 4” is performed by the manufacturer. This setting should
not be changed or selected in standard applications. These filter characteristics are optimized for custom specific applications, designed by the manufacturer. Using these filters in standard applications, the result a degrading of the measurement signal!
14.4.4 Zero point calibration
Using the Zero point calibration function the operator can recalibrate the zero point of your meter in the
measuring system. Zero point calibration is to be realized after any installation procedure or after any type
of work has been performed on in the pipes near the sensor.
Calibrating a sensor filled with a fluid is better than calibrating an empty one.
After choosing the Zero point calibration function and pressing „Enter“, the current remaining flow will be
displayed:
According to the description in Section13.4.3.1 Selection window/make a selection, the operator can toggle between [yes] and [no]. After setting the new value, press „Enter“ to confirm your entry. Enter [yes] to
have the zero point recalibrated.
14.4.5 Filter
For a noise reduction of the actual readings and minimizing disturbances on the sensor lines signal filter
are used. Following settings are available:
weak
mid
standard (factory setting)
strong
special
Selecting of “weak”, “mid” or standard influences the dynamics of the actual readings just less. The setting of damping time (see section 14.4.1 “Damping” at page 56 above) determines the dynamic behavior
of sensor and transmitter. Filter “strong” operates as an intense low pass filter to reduce the noise of the
actual readings. Then if setting the damping time shorter than 3 seconds, the low pass filter determines
the dynamic behavior to actual reading’s variations.
According to the description in section 13.4.3.1 Selection window/make a selection, the operator can toggle between noise filter types. After setting the new value, press “Enter” to confirm your entry.

complete some internal calculations.
According to the description in chapter 13.4.3.1 “Selection window/make a selection” the selection can be
switched to “yes” and the reference values for the density measurement are taken over. Thereupon to
activate density measurement it must be switched on as described in 14.6.1 “Density measurement

14.8.4 Pulse width
This function allows the operator to change the width of the output pulse to be output. If the pulse width is
too large for the actual pulse number, it will be reduced automatically. In this case the warning “Pulse
output saturated” will be displayed.
After selecting the Pulse width function, press „Enter“ to display the following selection field:
0.001, 0.01, 0.1, 1.0, 10.0, 100.0
The current pulse width will be displayed. As mentioned in Section 13.4.3.2 Input window/modify a value,
the operator can change the current value.
The maximum output frequency can be calculated from the following formula:
If connecting to electrical counter relays, we recommend pulse widths greater than 4 ms; for electromechanical counter relays the preset value should be 50 ms.

14.11 SIMULATION functional class
The functional class SIMULATION is comprised of the functions for simulating the outputs. If simulation is
activated, all output signals will be generated based on the selected type of simulation. The peripherals
connected to the device can be tested without a flowing product.
Simulation will be deactivated automatically if the operator switched the device off or did not touch any
control unit keys for about 10 minutes. Simulation can also be activated and controlled via HART® commands.

14.11.1 Simulation on/off
The Simulation on/off function allows the operator to activate or deactivate simulation. If simulation is
activated, all output signals will be generated based on the selected type of simulation. The peripherals
connected to the device can be tested without a flowing product. Press „Enter“ to display the current status.
As mentioned in Section 13.4.3.1 Selection window/make a selection, the operator toggle between the
“on” and “off.”
Simulation will be deactivated automatically if the operator switched the device off or did not touch any
control unit keys for about 10 minutes.
14.11.2 Direct simulation
This function allows the operator to define whether simulation is comprised of the measurement of the
three physical values mass flow, density and temperature or whether the outputs will be set directly.
Press „Enter“ to display the selected type of simulation.
As mentioned in Section 13.4.3.1 Selection window/make a selection, the operator can choose between
the following settings:
Direct pulse and current outputs are programmed directly
QM, D, T a measurement is simulated
If “direct” simulation is activated, any output will perform based on the settings described in Sections
14.11.4.1 Status output simulation to 14.11.4.4 Simulation current output I2. It is therefore recommended
that the settings be defined before starting simulation. They can then be purposefully changed during
simulation.
The status of the outputs during measured value simulation based on the setting “QM, D, T” depends on
the selected simulation values of these three variables, the measuring range settings and the assignment
of the outputs. If, for example, the pulse output is assigned to volume measurement, it will be affected by
all three simulation values at the same time [V ≈ QM (T) / D (T)].
Simulation will be deactivated automatically if the operator switched the device off or did not touch
any control unit keys for about 10 minutes.

14.11.3 Measured value simulation
If the operator selected the setting “QM, D, T” described in Section 14.11.2 on page 82, the following
three possible settings will affect the output behavior during measured value simulation, where all measured values are simulated at the same time.
14.11.3.1 Simulation mass flow QM abs
In order to simulate mass flow, the operator can define a “measured value.” The flow rates will be simulated in both directions. All outputs will perform based on the simulated measured value.
The simulation value is entered as described in Section 13.4.3.2 Input window/modify a value.
14.11.3.2 Density simulation
In order to simulate density/volume measurement, the operator can define a “density measured value.” If
volume measurement is assigned to an output, it will change depending on mass flow and density simulation. All outputs will perform based on the simulated measured value.
The simulation value is entered as described in Section 13.4.3.2 Input window/modify a value.
14.11.3.3 Temperature measurement simulation
In order to simulate a temperature, the operator can define a “measured value.” All outputs will perform
based on the simulated measured value.

page 82, the following four possible settings will affect the output behavior during measured value simulation, where all measured values are simulated at the same time.
14.11.4.1 Status output simulation
The Status output simulation function allows the operator to purposefully activate the status output.
Press „Enter“ to display the current state.
As mentioned in Section 13.4.3.1 Selection window/make a selection, the operator can toggle between

output. After selecting this function and pressing „Enter“, the following selection field will be displayed:
This field shows the current frequency. As mentioned in Section 13.4.3.2 Input window/modify a value,
the definable frequency ranges from 6 Hz to 1100 Hz.
14.11.4.3 Simulation current output I1
This function allows the operator to define a current for current interface 1. Press „Enter“ to display the set
current.
As mentioned in Section 13.4.3.2 Input window/modify a value, the current value can be changed.

14.12 SELF-TEST function class
The SELF-TEST function class is comprised of the functions relating to the self-test of the sensor.
The diagnostic functions of the transmitter, which monitor the proper functioning of the electronics and the
software, are always active and cannot be switched off. The excitation current can be monitored in addition.
The excitation current of each sensor in the system individually depends on the sensor itself, the fluid and
the installation conditions. If the excitation currents changes while the fluid remains the same, conclusions
may be drawn for e.g. potential wear and tear, viscosity changes or air bubbles. The operator has the
possibility of defining a “normal state” (“Self-test calibration”) and setting the limit for a permissible deviation. This function is deactivated in the device when delivered.

14.12.1 Sensor test on/off
The Sensor test on/off function allows the operator to activate or deactivate the monitoring function of the
excitation current.
According to the description in Section 13.4.3.1 Selection window/make a selection, the operator can
toggle between “on” and “off.” The standard factory setting is “off.”
14.12.2 Max. deviation of excitation
This function allows the operator to define a limiting value in the form of a percentage deviation from the
normal value. The excitation current is electronically limited to 50 mA (display value 500) and may take on
larger values for only a limited period of time (transient reactions).
The current limiting value is displayed. As mentioned in Section 13.4.3.2 Input window/modify a value, the
value can be changed taking into account permissible fluctuations.
14.12.3 Self-test calibration
Since the quantity of the excitation current does not only depend on the sensor itself but also on the installation conditions and the viscosity and density of the fluid, the normal value can only be calculated on
site during operation using the Self-test calibration function.
If the operator toggles to [yes] according to the description in Section 13.4.3.1 Selection window/make a
selection, the normal value will be calculated automatically. No additional information is needed for this
function.
14.12.4 Monitoring of sensor amplitude and excitation current
The first line of this window contains the amplitudes of the sensor signals S1 and S2 in 10 µV. Both values should be close to each other or identical (ideal case). The second line shows the excitation current
in 10 µA units.
Example: The sensors have amplitudes of 77.49 mV and 78.12 mV. The excitation current is 12.8 mA.
These values are used as reference values for the self-test function. They are measured by using the
function 14.12.3 Self-test calibration on page 86. Afterwards they can be displayed or edited by this function.

actual resonance frequency is 112.8 Hz.
The combination with the raw value display (see chapter 14.1.14 Raw values on page 50) supports the
analysis of all electrical signals between mass flow sensor and transmitter.

14.13.4 Reset system error
The integrated diagnostic system of the UMC4 transmitter distinguishes between two types of errors (see
also Section 17 UMC4 transmitter error messages). Self-test errors such as problems with a sensor line
or inconsistent parameter inputs are displayed as textual error messages. Once the error has been eliminated, the message automatically disappears from the display. For further information, see Section 17.3.1
Display of self-test errors.
Errors that are attributable to system memory or software, division by zero, or a fault in the electronics
unit are designated as system errors. These error messages are not reset automatically after the error
(usually of very brief duration) is eliminated. Before resetting a system error manually, we advise that
you contact our technical service department. For further information, see Section 17.3.1 Display of
self-test errors.
If the operator toggles to [yes] and confirms the action according to the description in Section 13.4.3.1
Selection window/make a selection, the error messages disappears from the display. If the message reappears shortly after, do contact our technical service department.
14.13.5 Profibus/Modbus device address
This setting is reserved for future communication developments and is presently unsed.
Before connecting fieldbus devices to a bus system, the operator must define a device address. This

Note:
The sensor constant must always be preceded by a plus or minus sign. The delivery default setting is a plus sign. If inlet and outlet section are interchanged when the device is
installed (the flow direction is indicated by an arrow on the sensor), the transmitter will
display a “forward flow” negative measurement value. If the (plus or minus) sign of the

15. Density calibration
For continuous processes, which process only small variations in temperature and liquid media of comparable density, a density calibration can be carried out locally.
15.1 Conditions
For a local density calibration the following conditions must be fulfilled:
The sensor must be suitable for a density measurement. For all these sensors the manufacturer
offers a 3-point calibration with an accuracy of at least 5 g/l. Sensors, for which the manufacturer
calibration is not offered, are also not suitable for local single point calibration.
For the local calibration the medium’s density must be known or be determined by a suitable pro-
cedure using exactly the same process temperature present in the sensor during measurement.
The medium must be liquid. The one-point density calibration is not suitable for gaseous media.
15.2 Procedure
The procedure of the density calibration is as follows:
First the transmitter is switched on and the sensor is filled with the medium under operating con-
ditions.
So that the sensor including housings and flanges can take the operating temperature a waiting
period of at least 15 minutes is to be kept.
After the input of the customer’s password select functional class DENSITY and “density calibra-
tion hot medium”. (See also chapter 14.6.15 on page 68.)
Independently of the kind of the liquid medium and its temperature the beginning of the calibra-
tion is confirmed by selecting “yes”. Thereupon the transmitter measures medium temperature
and current resonant frequency of the sensor.
In the following the function “measured values hot medium“ has to be selected The displayed
measured values of temperature and frequency are confirmed by 2 times pressing the Enter-key.
In the next field the density of the medium has to be entered in unit of g/l or kg/m³. (See also
chapter 14.6.16 on page 68.)
Subsequently, the function “finish density calibration” is used to finish density calibration. (See al-
so chapter 14.6.17 on page 68.)
Finally the function “density measurement on/off” activates the density measurement. (See also
chapter 14.6.1 on page 64.)
Now the measured density and also volume flows can be indicated or assigned to one of the out-
puts e.g. current output 2.

17. UMC4 transmitter error messages
The integrated UMC4 transmitter distinguishes between two types of errors. Self-test errors such as problems with a sensor line or inconsistent parameter inputs are displayed as text error messages. Once the
error has been eliminated, the message automatically disappears from the display. For further information, see Section 17.3.1 Display of self-test errors.
Errors that are attributable to system memory or software, division by zero, or a fault in the electronics
unit are designated as system errors. These error messages are not reset automatically after the error
(usually of very brief duration) is eliminated. Before resetting a system error manually, we advise that
you contact our technical service department. For further information, see Section 17.3.2 Display of
system error.
If the cause of any of the error messages described below cannot be eliminated, contact the device vendor.
17.1 Standard operating mode
The transmitter operates as described above. After the cause of the error message has been eliminated,
the message automatically disappears. The self-test for monitoring the excitation current can be activated
or deactivated via the “Sensor test” function.
17.2 Custody transfer mode
The transmitter UMC4 is not certified for custody transfer applications.
17.3 List of error messages
17.3.1 Display of self-test errors
Self-test errors are displayed as plain text in the set language (German or English) on the second line of
the LCD.

Check the lines between sensor
coil and transmitter. Measure coil
resistance.
Schwingt nicht
Does not vibrate
The measuring loops do not vibrate. The measuring system
does not work
Non symmetric filling of the flow
tubes = different filling of the
measuring pipes. Air inside the
flow tubes = high content of air
bubbles. Foam arising through
air contents or decompression
effects. Residues from media at
the tube walls e.g. wax from
hydrocarbons, crystallized media, condensate when measuring
vapor or gas.
Remedy
Fill or empty the flow tubes completely – disconnect transmitter
from power for min. 30 sec. –
connect to power again.
Electrical cause:
Check the wires between exciter
coil and transmitter. Check exciter coil function and magnet
(only HM certified service personnel). Check exciter wires to
short circuit with sensor housing.
Erreger zu groß
exc. too large
A excitation current exceeding the
limit will be detected.
Erreger zu klein
exc. too small

17.3.2 Display of system error
System errors consist of the message text “system error” and a 5-digit number in hexadecimal code. The
meaning of the individual error codes is described in the following table. If several errors occur at the
same time, the hexadecimal sum of the individual errors will be displayed. The errors are coded in such a
way that the individual errors can be easily identified. The sums are unique.
