Proper use of the device
The Coriolis Mass Flow Sensor is intended for the sole use of direct and continuous mass flow
measurement of liquids and gases.
To ensure safety for people and the environment adhere to the installation and operational instructions
and warning in this manual.
Warning
The operator is responsible for ensuring that the material used in the sensor and
housing are suitable and that such material meets the requirements for the process
medium and the ambient site conditions.
The manufacturer accepts no responsibility for the selection of unsuitably materials.
Warning
Only sensors marked as EX-certified on their rating plates may be used in EX hazardous
locations. Standard equipment is not permitted for installation and use in EX hazardous
locations.
For installation within hazardous areas read the Ex-supplementary manual. It contains
all EX-relevant parameters for the sensor and the UMC transmitter.
Caution
To ensure the device performs correctly and safely, it must be shipped, stored, set up,
mounted, operated and maintained correctly.
Installation and servicing
The devices described in this manual are to be installed and serviced only by qualified technical
personnel such as a qualified Heinrichs Messtechnik electronics engineer or service technician.
Warning
Before servicing, the device must be completely de-energised and disconnected from all
peripheral devices. The technician must also ensure that the device is completely
disconnected from any live circuits.
Only original replacement parts are to be used.
Heinrichs Messtechnik GmbH accepts no liability for any loss or damage of any kind arising from
improper operation of any product, improper handling or use of any replacement part, or from

When returned, the device is to be accompanied by a document describing the problems encountered.
Please include in this document the name of a contact person whom our technical service department
can contact to enable us to repair your device as expeditiously as possible and minimize the repair costs.
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

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.
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.

Density,

Operating conditions
Installation
The sensor is to be protected, wherever possible, against valves, manifolds and similar fittings that generate
turbulence. The sensor is to be installed in accordance with the following instructions.
Diagram showing flowmeter installation
Flowmeter installation: A = sensor, B = valve, C = pipe clamps and supports.
The sensor is not to be used to support a pipe or
other pipe components.
Do not install the sensor in suspended pipes.
Do not adjust the position of a pipe by pulling or
grasping the sensor.
