Replacement of the transmitter electronics
Before replacing the transmitter electronics, read the safety instructions in Section 2.3, “Installation and
servicing” on page 9.
The data memory chip (DSB) with the calibrating data of the sensor is an integral component of the
transmitter. Removal and installation of the DSB is described in chapter 4.6, “DSB data memory module”
on page 36.
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.

OPERATING MANUAL TMU / UMC3
Heinrichs Messtechnik GmbH
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 sensor
Application domain of the TMU sensor
The TMU 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 can be utilised for the direct and continuous mass flow measurement of chemical fluids,
suspensions, molasses, paint, varnish, lacquer, pastes and similar materials.
Mode of operation
Measuring principle
The Coriolis mass flowmeter 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.
FC  2  m    
System configuration
The flowmeter consists of a sensor that is mounted in a pipe, and a transmitter (see Section 4.1 Application
domain of the UMC3 transmitter on page 33), 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 an 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.

Caution:
When mounted in the horizontal orientation (B), it is to be ensured that moisture or rain
cannot accumulate on the top surface of the device.
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 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 for the standard TMU mass flowmeter renders the device unsuitable for use with
hazardous fluids. Only sensors that meet the standards for safety instruments and which are declared as such
are suitable for use with hazardous fluids.
In such sensors, a pressure-tight duct in the pathway between the sensor and transmitter prevents fluid from
leaking out of a sensor in the event a sensor develops a defect.
In the case of welded containments, a coloured liquid penetration test can be performed on the welds, or the
first seam of the weld can be x-rayed.
Alternatively, an internal pressure-monitoring device can be used to detect ruptured pipes.

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. The following drawings depict a recommended means of
installation for sensors up to a nominal size of approx. DN 040 (2”).

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
According to PN16 (Class 150) and PN40 (Class 300) etc. pressure ratings.
Outlet pressure
Outlet pressure must be greater than the vapor pressure Ps of the measured product.
Connection to the transmitter
3.4.10.1 Integral mount configuration
When the transmitter is mounted directly on the sensor, no cable connection between the two components is
needed. This connection is assembled at the factory.
3.4.10.2 Remote mount configuration
If the transmitter is not mounted directly on the sensor, installation regulations and applicable legal standards
are to be adhered to.
The maximum cable length is 200 m (approx. 650 ft). See Section 5.1.3 on page 46 for information regarding
the connection and cable specifications.

4. UMC3 transmitter
Application domain of the UMC3 transmitter
The UMC3 transmitter (hereinafter referred to as UMC3) 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 BE2 control unit, the UMC3 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.
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
UMC3 measures and evaluates signals received from sensors positioned on the flow tubes (see Section
3.2.1, “Measuring principle” on page 12).
System configuration
Transmitter:
The UMC3 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.
UMC3 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 flow
ranges” on page 13.
Repeatability error
 0.05 % of the actual value (Sensor with transmitter).
For more details refer to the sensor data sheet or section 3.3.2, “TMU flow ranges” on page 13.
Influence of ambient temperature
Max.  0.05 % per 10 °C
OPERATING MANUAL TMU / UMC3

Operating conditions
Installation conditions and cable glands
The integral mount version of the UMC3 shall be installed in accordance with the sensor installation
requirements stated in section 3.4.1, “Installation” on page 18.
When selecting the position of installation, especially for the remote-mounted UMC3, 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 46).
NPT cable glands
The transmitter housing is available with either M20x1.5 or NPT ½“ threaded cable gland entries.
For other threaded entries cable glands the manufacturer adds certified adapters. These adapters are
mechanically fixed to the thread of the transmitter housing.
Warning:
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.

Process conditions
For detailed information on the process conditions and specifications, please refer to section 3.5,
“Construction details”.
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.
DSB data memory module
The replaceable plug and play memory module is mounted on a printed board and stores all sensor data such
as sensor constants, model numbers, serial numbers, and so on. Consequently, the memory module is linked
to the sensor and is attached to the transmitter housing with a nylon cord.
If the transmitter is replaced, the memory module should be transferred to the new transmitter. When the
flowmeter is started up, the device continues using the values stored in the memory module. Thus, the DSB
memory module provides maximum safety and comfort when device components are replaced.
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 may be
damaged when exposed to ESD hazards. Only when installed in the transmitters
enclosure are the electronics compliant to EMC standards.

Socket for DSB
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 within, the memory devices are not arbitrarily
interchangeable between identically constructed transmitters.
Input measured variables
Measured Values
The UMC measures via the connected sensor the following variables:

mass flow rate,

temperature,

density

HART®
A number of connection possibilities are available for HART® communication, with the condition that the
loop resistance is less than the maximum load specified in Section 4.8.2, “Current outputs” on page 39. The
HART® interface is connected via terminal 11 and 12 or 41 and 42 respectively. The minimum load
impedance of 250 Ω must be adhered to.
For information regarding operation of the transmitter using the HART  hand-held terminal, see refer to the
supplementary manual; ”UMC-HART_BA_20.01_en“.
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 UMC3, 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 23
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.

7. Operation
Control unit BE4
Introduction
The UMC3 transmitter can be operated using control unit BE2, a desktop or laptop computer in conjunction
with SensorPort software, or via HART® Communicator.
In the following, transmitter operation and parameterization using control unit BE2 (normally integrated into
the terminal compartment) are described. The control unit can also be connected to the transmitter using an
intrinsically safe cable that is up to 200 m in length. This allows a point-of-use display to be installed in a
control room so that readings, counter status and settings can be accessed ergonomically.
Control Unit BE2
The BE2 Control unit of the UMC3 has an integrated alphanumeric display with two 16-character lines
(format 16 x 60 mm). 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 on the LCD and the liquid crystals can dry out.

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 “ “, the following selection field will be

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 “ “, the current remaining flow will be
displayed:
QM = 0,00 kg/h
cal. ? [no]
The operator can toggle between [yes] and [no]. Entering [yes] initiates a new zero point calibration.
After setting the new value, press “ “ to confirm your entry.

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.

7.2.13.4 Reset system error
The integrated diagnostic system of the UMC3 transmitter distinguishes between two types of errors (see also
Section 8.2, “UMC3 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”.

Fieldbus devices (Profibus PA, Modbus RTU) only:
Before connecting fieldbus devices to a bus system, the operator must define a device address. This address is
a unique assignment to a participant device in a bus system (similar to a street number).
Upon delivery of each unit with Modbus or Profibus interface has the default address “001”
A non-assigned address (< 248) must be set before commissioning of the plant for each newly added device.
After selecting the Profibus/Modbus device address, press “” to display the set address:
Device address

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).
1.1.1.2
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
factory.

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 3-point
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 79).

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 79).

Subsequently, the function “finish density calibration” is used to finish density calibration. (See also chapter
7.2.6.17 on page 79).

Finally the function “density measurement on/off” activates the density measurement. (See also chapter
7.2.6.1 on page 74).

Now the measured density and also volume flows can be indicated or assigned to one of the outputs e.g.
current output 2.

UMC3 transmitter error messages
The integrated diagnostic system of the UMC3 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 is
acknowledged via the “Reset” button.
