1.3 Required differential pressure
Density transducers of the DIMF series measure independently of flow rate and also at flow rate zero.
Their application is therefore normally problem-free. Care must, however, be taken to ensure that the
operating flow rate in the transducer
- updates the sample fast enough
- equalizes the temperature in the tranducer
- avoids air or gas bubbles or
deposits in the oscillating tube
- does not cause cavitation in the oscillating tube
- does not cause wear through abrasives
Recommended operating flow rate through the density transducer:
DIMF 2.0: approx. 2.0 l/m.

2 Intended use
The density transducer type DIMF allows the continuous measurement of the density of liquids and liquid
mixtures. The proven oscillating element principle ensures great accuracy in combination with
outstanding long-term stability. The easy-to-get-on-with-construction assures reliable operation, even
under tough process conditions.
3 Measuring principle
The real sensor of the density transducer is an oscillating element in the form of a tube bent into a tuning
fork. The liquid to be measured passes continuously through this element. Excited electromagnetically by
an excitation coil, it will oscillate at its natural frequency. Changes in the density of the liquid lead to
changes in the natural frequency. This change in frequency, sensed by a pick-up coil, represents the
measurement effect. An additional built-in resistance thermometer measures the process temperature,
which can also be used to equalize the temperature influence in the transducer.
Each density transducer is calibrated with different liquids of different densities. The transducer constants
for the calculation of the density from the frequency, the calibration temperature and the correction
coefficients for temperature influence are given under section 16.4 Example of configuration log.
4 Installation examples
In principle, the density transducer can be installed directly into the product line (for permissible flow
rates, see section 1.3). For higher flow rates or measurements at containers, installation in a by-pass is
recommended.

4.2 Installation into the product line
Installation into the product line is possible up to a flow rate of 50 l/min (using H2O as an example). For
other viscosities, differing pressure losses must be considered.
Caution!
The pressure in the product line must never fall below the vapor pressure. Direct solar irradiation of the
density transducer must be avoided. If necessary, heat insulation must be provided.
4.3 Examples for installation positions
The device may be mounted in any position. However, depending on the properties of the liquid and the
flow velocity, the following positions are recommended:
Mounting position A: standard mounting position, e.g. for clean liquids at low
flow velocities
Mounting position B: self-draining position
Mounting positions C or D: for liquids with solids
5 Mounting
5.1 Density transducer
- Handle with care: do not knock the density transducer.
-Install density transducer into by-pass or directly into the product line.
- Deaerate the device before putting it into operation.
- Provide a constant flow through the density transducer.
- Any flow direction is possible.
- Normal flow rate to be approx. 1.5 to 6 l/min, max. 50 l/min
(provides current liquid sample, avoids deposits)
- Avoid generation of steam bubbles.
- The use of a clamp or a bracket is recommended
(e.g. mounting plate, pipe or wall clamp).
- If mounting position is "self-draining",
a clamp or a bracket must be used.

- Connected loads power supply voltage
Umax = 30 V Imax = 110 mA Pmax = 825 mW
Ci ≤34 nF Li ≤0.6 mH
- Power supply must be provided by a certified, intrinsically safe supply unit or by
safety barriers.
- In order to connect the bonding conductor safely, use the
internal and external bonding connector terminals, which have been designed
for a wire range of 1.5 mm² (inside) or 4 mm² (outside).
- If barriers are part of the supply circuit, they must also be connected to the common
bonding conductor.
7 Commissioning
- Flush product lines before connecting the density transducer
- Ensure that all connections are tight
- Deaerate density transducer
- Switch on power supply
8 Factory setting
The density transducer DIMF 2.0 TR has been parameterized according to customer specifications. After
switching on the power supply, the specified parameters (e.g. density, reference density or concentration)
and the operating temperature will be shown on the display.
If these parameters have changed since the order was placed, the setting can be modified (see
section 10 Configuration, operation).

provisions, we reserve all rights.
9 On-site adjustment
An on-site adjustment is carried out if an error has been confirmed due to certain on-site conditions after
the reasons according to section 13.1 have been checked. By changing the transducer constant K0, a
simple adjustment can be performed.
Example: Measurement condition Temperature must be relatively stable
Rho (measured density) = 996.6 Kg/m³
Rho (setpoint value) = 996.0 Kg/m³ (e.g. value stated in table)
difference (misalignment)= +0.6 Kg/m³
current K0value = -7360.708 Kg/m³
setpoint K0value = K0(current) –
misalignment
correct K0value = - 7360.708 Kg/m³ - 0.6 Kg/m³
= -7361.308 Kg/m³
Now this value must be entered into the transmitter type TR.
If possible, the constants K1and K2should not be modified by the user.
Depending on the operating mode or application and the reason for the error, the adjustment can also be
carried out via the concentration coefficient KX0. Here the same procedure is applied.
10 Configuration, operation
The transmitter can be configured (operated) in two different ways:
1. HARTcommunication
2. On-site operation with keys and display
10.1 Operation via HARTcommunication
The device can be operated using a PC or laptop and the SensorPort 2 configuration software in
connection with a HARTinterface.
A HARTCommunicator is another operating element which can be used (e.g. model HC-275 of
Rosemount). The operating functions of the HC-275 are defined in the HART "Device Description
Language" (DDL). Using the HC-275 the DIMF can be operated or configured on site. For the electrical
connection, see section 16.1.

available to third parties. In case of violation of the aforementioned
provisions, we reserve all rights.
10.1.4 Operating modes
Simulation
Current simulation: In order to test the devices connected in series, a fixed output
current of 3.9 to 22 mA can be set. After the test, the current value
0 mA must be entered to end simulation.
Alarm 21.8 mA: An alarm signal can be transmitted via the current loop.
The current then rises to 21.8 mA. This alarm is generated due to a
maloperation of the DIMF. The alarm function can be switched off.
Selection of
measured variable: The measured variable has been assigned to the HARTprimary variable and
thus to the current output. When displaying density, the user can change
between operating or reference density. When calculating the concentration,
the user can select between the two different methods.
10.1.5 Special settings
Electronic adjustment
Calibrate current output: The characteristic of the analog current output can be calibrated in its zero
point at 4 mA and in its slope at 20 mA. It must be observed that the zero point
will be calibrated before the upper range value.
Reset device: With this command, the device can be restored to a defined operating state
present after the supply voltage was applied.
10.2 Operation with the keys (configuration via the control unit)
To access the keys, the screw cover of the longer end of the housing must be opened. When the housing
cover has been opened, the degree of protection of the housing is not ensured.
After the configuration has been completed, the housing cover must be remounted and the screws must
be fastened fingertight (be careful not to damage the sealing ring).
For the Exd version the housing may only be removed after it has been ensured that
there is no explosive atmosphere.
The covers of the Exd version are secured against opening. In order to open the cover, the locking bar
must be swiveled sideways and clamped in this position. After closing the covers, they must be
resecured.
10.2.1 Display
The transmitter type TR has a two-line display with 8 digits for each line. Each line is subdivided into two
fields:
- in the 1st field the channel no. is displayed (1 digit)
- in the 2nd field the corresponding measured values
or the constants are displayed (7 digits).
The values displayed in the upper line cannot be changed. The values displayed in the lower line
(programming line) can be changed.
The activated line is marked with a triangle behind the channel number. By pressing the ENTER key, you
can toggle between the lines.

- pressing this key for a couple of seconds resets the entry position (blinking digit)
10.2.3 Operating mode
In the operating mode, the measured values and constants displayed cannot be changed. When the
transmitter type TR is switched on,
- a display test is carried out
- the operating mode is activated automatically
- the current measured variable, density (kg/m³) or concentration (%),
depending on the operating mode, is displayed in the upper line
- the current temperature (°C) is displayed in the lower line
- the upper line is activated
If a different value is to be displayed in the lower line, the lower line must be activated by pressing "↵".
Then you select the corresponding channel no. (see table in section 10.3) by pressing " " or " " . Once
the last channel number has been reached the display moves back to the first channel. Once the first
channel number has been reached, the display moves to the highest channel no.
10.2.4 Programming mode
Depending on the operating mode, in programming mode, the device parameters and the medium
constants can be programmed or modified on site. The constants can only be programmed in the lower
line. For this, the "P" key must be actuated until the first digit blinks in the display field. This digit can then
be changed with the keys " " or " ". Pressing the ↵key moves you to the next entry position
(corresponding digit blinks). To place a comma, you press the P key for a short moment. After leaving the
last position, the channel is accepted with the current contents. By pressing the P key for approx. 3
seconds the current input position can be reset to the previous position.
- while programming the K0and KX0 values all measured and
calculated values are frozen;
the upper display line will not be activated.
- if the "programming" function has been initiated but not terminated,
it will be terminated automatically after approx. 2 minutes;
the old value will be restored.
- channel no. "]“ is used for displaying error codes;
these can be deleted by pressing the "P" key
(see error code table in section 13.2.1).

10.2.5 Operating mode
By selecting the operating mode (channel E) you define the calculation method according to which the
measured variable is to be acquired and the output signal is to be represented.
By selecting the operating mode you define
- the assignment of the primary HARTvariables (current output signal)
- the measured value in "channel 4".
The following operating modes are available:
- density in kg/m³ (for equation 1, 2 and 3, see section 11)
(there is a choice between operating density or reference density, depending on the
αvalue)
- concentration in % (for equation 1, 2, 4 and 5, see section
The analog output signal (4 to 20 mA) can be freely assigned to the desired measuring range (lower
range value: channel 5, upper range value: channel 6) within the meter range.
The minimum measuring range span should not be below a density range of 5 kg/m³.
