2.6
Replacement of the transmitter electronics
Before replacing the transmitter electronics, read the safety instructions in Section 2.4, “Installation and
servicing” on page 9.
The data memory chip (DAB) with the calibrating data of the sensor is an integral component of the
control unit (display BE4). Removal and installation of the control unit is described in chapter 4.6, “DSB
data memory module” on page 25.
Should an exchange of the transmitter electronics become necessary, it is essential that the whole
electronic stack is replaced. This comprises of all circuit boards in the electronic compartment and in the
terminal compartment. The overall accuracy of the measurement up to the analogous outputs can only
be guaranteed when all circuit boards are replaced. Only the control unit with the integrated memory for
the calibrating data of the sensor shall remain with the device.
Caution
The complete stack is to be replaced with all of its printed circuit boards (with the
exception for the display unit containing the memory module). This is particularly
important for the explosion-proof transmitter. The specified precision of the
electronics is only guaranteed if the complete stack is replaced.

2.7
Maintenance
Transmitter
The transmitter is maintenance-free.
We recommend cleaning the viewing-glass of the transmitter at regular intervals; check the enclosure for
corrosion damages and the solid seat of the cable glands.
Warning!
In the event an enclosure lid O-ring gasket is damaged, humidity may enter the
enclosure and cause damage to the internal electronic circuits.
Indications of such are:

Visible discolouration’s or condensation on the viewing-glass of the transmitter,

corrosion damages to the enclosure,
Coriolis mass flow sensor
The sensor is largely maintenance-free. When handled correctly its functionality will only be impaired by
corrosion or deposits inside of the measuring tubes. Therefore, both should be implicitly avoided. Remove
deposits in the tubes and in or around the splitter on a regularly basis by means of a suitably washing
method. Failure to do so may result in a loss of measurement precision.
Warning!
In the event of a tube rupture, e.g. due to corrosion or damage, medium will leak into
and fill the enclosures body, which can lead to subsequent damage to the external
housing, particularly at high process pressures!

3. The TMU-W sensor
3.1
Application domain of the TMU-W sensor
The TMU-W sensor is intended solely for the direct and continuous mass flow measurement of liquids and
gases under high pressure, irrespective of their conductivity, density, temperature, pressure, or viscosity.
The sensor can be utilised for the direct and continuous mass flow measurement of chemical fluids,
suspensions, molasses, paint, varnish, lacquer, pastes and similar materials.
3.2
Mode of operation
Measuring principle
The mass flowmeter is based on the Coriolis
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.
FC  2  m    
System configuration
The flowmeter consists of a sensor mounted in to a piping system and a remote installed transmitter (see
Section 4.1, “Application domain of the UMC4” on page 22), connected to the sensor via a special cable (e.g.
on a wall or to a pipe).
The transmitter oscillates the flow tubes of the sensor by means of an excitation coil and captures, via pickup coils, the measuring signal which is proportional to the mass flow. After temperature compensation, the
measuring signal is converted into an analogue output signal that is consistent with the measuring range
setting.

Pressure loss in Hydrogen dispensers
The pressure loss of gases with constant mass flow is highly dependent on the operating pressure in the
mass meter and the resulting flow rate. The TMU-W is designed that its pressure lost will not exceed 30 bar
during a standardized refuelling operation with hydrogen and an empty vehicle tank, as defined in the
SAEJ2601. With an almost full vehicle tank, the pressure loss shall be much less than 20 bar.

or similar factors. This change in pressure can lead to under-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 flowmeter,
a gas bubble can form in the flow tube that can cause a measuring signal disturbance that 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 tube.
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.
Using the device with hazardous fluids
The sealing technology used in the TMU-W mass flowmeters connector plug 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.
In the case of welded components, a coloured liquid penetration test can be performed on the welds, or the
first seam of the weld can be x-rayed.
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 supports shall be mounted such as
depicted in the following images. Such supports will prevent vibration from affecting the device’s
mechanical configuration and/or measurement readings.

Gas content
The use of products containing gases is not permitted for custody transfer operations. In other applications,
the presence of gas will increase false readings. For the readings of products containing gas to be valid,
small gas bubbles must be homogeneously distributed in the fluid.
Large gas bubbles will automatically provoke extremely false readings and will shift the zero point. Thus, the
extent to which readings are false is determined by the process conditions. A rule of thumb in this regard is
as follows: A 1 % gas component will increase false readings by 1 %. The gas component is not to exceed 5 %.
Process pressure range
The applicable pressure range is dependent on the sensor and the selected process connections. It is
essential that the correct process connections for the intended process pressure is selected during the
ordering process.

Connection to the transmitter
The sensors of the TMU-W family are only available as remote mount versions. The connection to the
sensor is achieved via a special ten-cored cable by means of a detachable screw-on connector.
During installation, regulations and applicable legal standards are to be adhered to.

4. UMC4 transmitter
4.1
Application domain of the UMC4 transmitter
The UMC4 transmitter (hereinafter referred to as UMC4) for use with TM, TME TMR, TMU, TM-SH and HPC
Coriolis mass-flow sensors, is a programmable transmitter designed to captured and processes
measurement data from its associated sensor for displaying on its built in display or for the transmission of
measurement results via various interfaces.
Via its BE4 control unit, the UMC4 can be customised for use to fit a variety of applications. Although basic
configuration settings such as transmitter calibration are factory performed, other parameters such as
those for measurement data processing, analysis, display and output are user definable.
4.2
Mode of Operation
The Coriolis mass flow meter works 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. Utilising a
suitable sensor construction, this force can be exploited for the direct measurement of the mass flow. The
UMC4 transmitter measures and evaluates signals received from sensors positioned on the flow tubes (see
Section 3.2.1, “Measuring principle” on page 12).
4.3
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 analogue, 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:
Coriolis sensors measure mass-flow, density and temperature of fluids or gases. They can be used to
perform measurements with any liquid or gaseous product providing that the sensor material is suitable for
the product to be measured.
4.4
UMC4 performance characteristics
Reference conditions
In conformity with IEC 770
Temperature: 20 °C (68 °F), relative humidity: 65 %, air pressure: 101.3 kPa (14.7 psi)
Measured error
For measurement errors and zero point stability refer to the sensor data sheet in section 3.3.2, “TMU-W
flow ranges” on page 13.
Repeatability error
 0.05 % of the actual value (Sensor with transmitter).

installation requirements stated in section 3.
When selecting the position of installation, especially for the remote-mounted UMC4, ensure a vibrationfree mounting.
Warning:
Cable glands are not contained in the basic scope of supply. The operator is
responsible for ensuring that cable glands or plugs according to the enclosures type of
EX-protection and the provided threads are used. The enclosures thread type is stated
on the transmitters rating plate.
Caution:
Where applicable, metalized cable gland must be used for the sensor / transmitter
cable to ensure a sufficient conductive connection for the cable shield.
(See section 5.1.3, “Sensor connection” on page 36)
NPT cable glands
The transmitter housing is designed for use with M20x1.5 threaded cable glands. For NPT threaded cable
glands the manufacturer adds certified NPT adapters. These NPT adapters are mechanically fixed to the
thread of the transmitter housing.
Warning:
NPT adapters mounted by the manufacturer may never be removed by the customer! In
the event of a removal of these adapters, the protection class Ex-d can no longer be
guaranteed.

cable glands or conduits are used. If the cable glands are not tightened sufficiently,
water may leak into the terminal compartment of the enclosure and cause damage to
the electronics.
Caution:
Particular care must be taken if the enclosures viewing window becomes fogged or
discoloured, which may be an indication of moisture, water or product seeping through
the wire sheath into the transmitter’s housing.
Caution:
Electromagnetic compatibility can only be guaranteed if the lids of the enclosure are
securely tightened. Leaving the enclosure open may lead to electromagnetic
disturbances.
Warning
In Ex hazardous areas, only sensors and transmitters marked as such on their rating
plates may be used!

Process conditions
For detailed information on the process conditions and specifications, please refer to section 3.3,
“Performance characteristics of the TMU-W sensor”.
When compact mounted, the process conditions can influence the operation of the transmitter if the
manufactures installation and operational conditions are not abided to.
Remote mounted transmitters are not affected by the prevailing process conditions of the sensor
Note:
Compact-mounted transmitters are not available for all versions of sensors.
4.6
DSB data memory module
The 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 installed onto the new electronic stack.
Warning:
When replacing the transmitter electronics, ensure that the applicable standards
and regulations pertaining to electrical devices, device installation and process
technology are abided to. The highly integrated electronic components of the UMC4
may be damaged when exposed to ESD hazards. Only when installed in the
transmitters enclosure are the electronics compliant to EMC standards.
Exchanging the Control Unit
To exchange the BE4 control unit abide to the following instructions referring to the image on the following
page.
After loosening the 4 screws situated below the foil, the control unit with the display can be detached
together with the foil. For this purpose, the foil itself does not need to be removed.
When transferring the BE4 PCB to a new electronic stack, care should be taken to ensure the correct seating
of the 10 poled connector. An incorrectly plugged connector will lead to malfunction and may also damage
the electronics.
OPERATING MANUAL TMU-W / UMC4
Page 25 of 118
Heinrichs Messtechnik GmbH
Removal and exchange of the BE4 Control unit:
The DSB Memory device is situated
on the rear side of the control unit
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.
Due to the device specific parameters saved in the memory device, the control units are not arbitrarily
interchangeable between identically constructed transmitters. Replace circuit boards must be ordered
from Heinrichs using the transmitter’s serial number specification. The calibration data of the sensor are
programmed into the delivered BE4 control panel directly by the manufacture
4.7
Input measured variables
Measured Values
The UMC4 measures via the connected sensor the following variables:


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).
For further details see section 3.4.10, “Connection to the transmitter” on page 19
4.8.2.4
Damping
The damping of the output signals is programmable from 1 to 60 seconds.
The standard factory setting is 3 seconds.
4.8.2.5
Error indication
An error in, or failure of the meter can be indicated via the current outputs or the status output. The current
outputs can be set to a failure signal (alarm) of I < 3.8 mA or I > 22 mA. The status output can be configured
as a make or break contact.
4.8.2.6
Low flow cut-off
The low flow cut-off can be set to values between 0 and 20% via the menu. The set value is a percentual
value of the upper-range setting. If the measured value is lower than the set cut-off, the flow rate will be
set to 0.0 (kg/h). This results in the analogue output being set to 0/4 mA, and the pulse output will cease
generating pulses.
Binary Outputs
The binary outputs utilise NPN transistors for the transmission of their data. To collect this data (e.g.
Pulses), the connection of an external circuitry is necessary. Image 3 depicts an example of such a circuit.
For use in EX atmospheres, refer to the EX-supplement manual for additional connection requirements.

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.

Low flow cut-off
The value for low flow cut-off (low flow volume) is a limiting value stated as a percentage that relates to the
upper-range value of the flow rate. If the volume drops below this value (e.g. leakage), the displayed value and
the current outputs will be set to “ZERO.” The value for low flow cut-off can be set from 0 to 20 % in 1-percent
increments. After choosing the Low flow cut-off function and pressing “Enter“, the following selection field will
be displayed:
Low flow cut-off

7.2.4.3
Low flow cut-off hysteresis
The hysteresis of the low flow volume is the flow rate expressed as a percentage of the upper range
value by which the volume must fall below or surpass the set low flow volume in order to activate or
deactivate the function. The hysteresis of the low flow volume can be set in 1-percent increments
from 0 to 10 %. After selecting the Low flow cut-off hysteresis function and pressing “Enter“, the
following selection field will be displayed:
Low flow cut-off
Hysteresis 00 %
The current hysteresis will be displayed and can be changed by toggling the arrow keys.
Pressing the “Enter” key confirms the entry
7.2.4.4
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.
Caution:
It is important that this function is only performed when certain that the medium in
the sensor is not moving (flowing). Otherwise, the subsequently measured flow rates
will provide an incorrect zero-point. The sensor may be completely empty or filled
with medium. A partially filled sensor or a fluid containing air bubbles will lead to an
incorrect zero point calibration.
Note:
Calibrating a sensor filled with a fluid is preferable than calibrating with empty
tubes!
After choosing the Zero point calibration function and pressing “Enter“, the current remaining flow
will be displayed:
QM = 0,00 kg/h
cal. ? [no]
The operator can toggle between [yes] and [no].
After setting the new value, press “Enter“ to confirm your entry. Entering [yes] initiates a new zero point
calibration.
OPERATING MANUAL TMU-W / UMC4
Page 59 of 118

7.2.4.5
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 7.2.4.1, “Damping” at page 58 above) determines the dynamic behaviour 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 behaviour
to actual reading’s variations.
Note:
Setting of the filters “special 1” to “special 4” is carried out by the manufacturer.
These filter characteristics are optimized for specific custom applications, defined by
the manufacturer. Using these filters in standard applications, can result in a
degrading of the measurement signal! To use of these filters, consult the
manufacturer.
The operator can toggle between noise filter types with the arrow keys. After setting the new filter type, press
“Enter“ to confirm your entry.

Pressing the “Enter” key confirms the entry.
If “direct” simulation is activated, any output will perform based on the settings described in Section 7.2.11.4,
“Direct simulation of outputs”. 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)].

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.
7.2.12.1

The current setting is displayed and can be changed by toggling the arrow keys.
The operator can toggle between “on” and “off.” The standard factory setting is “off.”
Pressing the “Enter” key confirms the entry.
7.2.12.2
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).
Max. deviation

The current value will be displayed and can be changed by toggling the arrow keys.
When changing the max. deviation value, permissible fluctuations shall be considered.
Pressing the “Enter” key confirms the entry.
7.2.12.3
Self-test calibration
The magnitude of the excitation current not only depend on the sensor itself but also on the installation
conditions and the viscosity and density of the fluid. Therefore, the “normal” value can only be determined at
the installation site during operation using the Self-test calibration function.
Calibration
[no]
The current setting is displayed and can be changed by toggling the arrow keys.
When set to [yes], the “normal” value is automatically calculated. No additional information is required for this

Reset system error
The integrated diagnostic system of the UMC4 transmitter distinguishes between two types of errors (see also
Section 8.2, “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 8.2.3.1, “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 you to contact our technical
service department. For further information, see Section 8.2.3.1, “Display of self-test errors”.
Reset error
[no]
The setting “no” will be displayed and can be changed by toggling the arrow keys.
If the operator toggles to [yes] and confirms the action by pressing “Enter”, the error messages disappear from
the display. If the message reappears shortly after, contact our technical service department for help.

Profibus/Modbus device address
Note: This setting is reserved for future communication developments and is at present unused.
Before connecting fieldbus devices to a bus system, the operator must define a device address. This address is

Sensor constant C
Sensor constant C is the sensor calibration value for mass flow. This constant is defined when the flowmeter is
calibrated at the factory and can be found on the rating plate.
Sensor constant
+0150.00 kg/h
Caution:
Changing the sensor constant C to a value that differs from the value on the rating
plate of the sensor will result in incorrect mass-flow measurements.
Normally, the sensor constant is changed only when the device is calibrated, e.g. for a validation measurement
for a custody transfer operation.
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 sensor constant is then changed without changing the actual value,
a plus sign will again be displayed. No changes need be made in the disposition of the
electrical connections (wires).
7.2.14.2
Sensor material
The Sensor material function allows the flow tube material code to be entered. This material code can be found
on the sensor rating plate. This setting is defined by the vendor when the device is first put into operation at the

Alarm can be activated or deactivated. If activated [yes] a reverse flow below the set value “limit for reverse
flow“ (see 7.2.15.11, “Limit for reverse flow”) will result in an alarm.
The default value for “alarm if reverse flow” is [no].

This parameter selects the behaviour of the pulse outputs in the event of an alarm during a flow delivery.
The following choices are available for selection:


No Alarm - Both outputs continue pulsing
Stop IMP2 - Pulse 2 is stopped. Pulse output 2 is disabled while pulse output 1 continues delivering
pulses.

Stop IMP1,2 - Both outputs are stopped, no pulses are delivered.
The default value for “pulse outputs at alarm” is [Stop IMP2]

Density calibration
For continuous processes, where only small variations of temperature are experienced and where only liquid
medias of similar density are used, the user can perform a density calibration locally by at the place of installation.
Note:
Density measurement is not available for all sensor types.
Before proceeding with the density calibration described in this chapter ensure that,
your sensor is capable of density measurement.
Conditions
For a local density calibration the following conditions must be fulfilled:

The sensor must be suitable for a density measurement. Contact our service department to check the
suitability of your sensor for a density calibration. For all suitable sensors, the Heinrichs offers a 3point calibration with an accuracy of at least 5 g/l. Sensors, for which the manufacturer calibration is
not available, are not suitable for local single point calibrations.

For the local calibration the medium’s density must be known or be determined by a suitable procedure
using exactly the same process temperature present in the sensor during measurement.

The medium must be liquid. For gaseous media the density calibration is not suitable.
Procedure
The density calibration procedure is as follows:

The transmitter is powered up and the sensor is filled with the medium under operating conditions.

A waiting period of at least 15 minutes is to be given, to allow the sensor including its enclosure and
flanges can adopt the operating temperature.

After the input of the customer’s password select functional class DENSITY and “density calibration hot
medium” (See chapter 7.2.6.15, on page 72).

Independent of the type of liquid medium and its temperature the beginning of the calibration is
confirmed by selecting “yes”. Thereupon the transmitter captures the medium temperature and
current resonant frequency of the sensor.

Subsequently the function “measured values hot medium“ must be selected, the displayed measured
values of temperature and frequency are confirmed by pressing the Enter-key two times. In the next
field the density of the medium must be entered in unit of g/l or kg/m³. (See also chapter 7.2.6.16 on
page 72.)

Subsequently, the function “finish density calibration” is used to finish density calibration. (See also
chapter 7.2.6.17 on page 72.)

Finally the function “density measurement on/off” activates the density measurement. (See also chapter
7.2.6.1 on page 67.)

Now the measured density and also volume flows can be indicated or assigned to one of the outputs e.g.
current output 2.

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 8.2.3.1, “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 8.2.3.2, “Display of system error”.
If the cause of any of the error messages described below cannot be eliminated, contact the device vendor.
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.
Custody transfer mode
When the device is placed in Custody transfer mode, any errors will remain on the display until the error itself
has disappeared or until the error is acknowledged via the “Enter” button.
All error occurrences and parameters amended whilst in Custody Transfer Mode are logged in an Audit log file,
which can be requested via HART®.
