3.4 The principle of density measurement
The density measurement is based on the electromagnetically
induced oscillation of a U-form tube made of glass. A magnet is
fixed to the U-tube and a transmitter induces the oscillation. The
period of oscillation T is measured by a sensor.
A complete forward and backward vibration is known as a
period, its duration is the oscillation period T. The maximum
deflection in the vertical direction is the amplitude A.
Measuring tube with defined volumetric capacity:
A) Excitation: Magnetic
B) Detection: optical
The number of periods per second is the frequency f. Each glass tube oscillates with its own intrinsic frequency:
Design and function10 Density Meter Excellence
The frequency is a function of the total mass and changes when the tube is filled with a gas or liquid. If the

mass is increased, the frequency falls, i.e. the period of oscillation T becomes longer, according to the below
formula:
: Density of the sample in the measuring cell [g/cm3]
VC: Volume of the sample (capacity of the measuring cell) [cm3]
mc: Mass of the measuring cell [g]
K: Measuring cell constants [g/s2]
The density ρ can hence be calculated as follows:
The relationship between the density and the period of oscillation T is as follows:
A and B are constants that depend on the elasticity, structure and mass of the measuring cell. As they vary from
cell to cell, they must be determined by means of direct measurement. This is known as a coefficient determination or adjustment of the instrument. The coefficient F of the measuring cell is calculated by measuring the
period of oscillation T of two standard substances (usually air and water) with known densities:
= Density of air [g/cm3]
A
= Density of water [g/cm3]
W
TA = Period of oscillation of the air measurement [s]
TW = Period of oscillation of the water measurement [s]
After the coefficient F of the measuring cell has been determined by an adjustment, the unknown density of a
substance S can be calculated via the following formulas, whereby TA, TS and TW in the following formulas no
longer represent the period of oscillation itself but the oscillation value OSC derived from it:
The following diagram shows the how the density of an unknown substance is determined:
Design and function 11Density Meter Excellence

S

Note
The coefficient F is temperature-dependent. The volume of the measuring cell and hence its period of oscillation
changes with the temperature. For very precise measurements, the coefficient of the cell should be determined
for the temperature at which you measure your samples.
The oscillation value OSC described here is required to calculate the coefficient of the measuring cell and hence
the density of the unknown sample. The period of oscillation T itself is not displayed on the instrument. The
density meters only display the so-called oscillation value OSC that is directly derived from the period of oscillation T.
The oscillation value OSC is thus only an auxiliary value that represents the period of oscillation in high
resolution as a whole number without digital places.
3.5 Design of the measuring cell and the temperature controller
For a specific determination of the density a very precise measurement and adjustment of the temperature must
be ensured.
As the temperature of the probe cannot be measured directly in the U-form tube without falsifying the
measurement of the oscillation, the temperature is measured via three thermistors at different locations. The
temperature is measured at four different points:
Temperature 1: Sensor in the measuring cell, directly above the surface of the U-tube. This temperature
is shown as a status display (cell temperature).
Temperature 2: Temperature of the thermoblock (block temperature) (not displayed)
Temperature 3: Reference temperature (not displayed)
Temperature 4 Ambient temperature (not displayed)
The following schematic diagram shows the design of the module:

(ambient temperature)
During a measurement the temperature of the sample must be regulated (heating or cooling) to precisely
correspond to the selected measuring temperature. The density of the sample changes during heating or
cooling (density is temperature-dependent!). The same is true for the resonance frequency of the U-tube. The
sample temperature corresponds exactly to the selected temperature (and hence the cell temperature, Sensor 1)
when the resonance frequency stabilizes. However it takes a long time before this thermal equilibrium is
completely established. With respect to the shorter measuring times, various measurement reliabilities can be
chosen so that even before the measurement is completed the temperature and the OSC can be extrapolated to
stable end values. This means that sufficiently accurate results can be obtained before stabilization:
End of the measurement with:
1) Meas. reliability "Maximum":
T and OSC stable
2) Meas. reliability "High": T
and OSC extrapolated; narrow
tolerance
3) Meas. reliability "Medium": T
and OSC extrapolated; medium
tolerance
4) Meas. reliability "Minimum":
T and OSC extrapolated; greater
tolerance

operating instructions for the measuring instrument concerned):
Manual end point measured value acquisition,
set the unit [pH]" ([mV] not supported).
2 For the SevenCompact pH and conductivity meters, the following must also be selected (also refer to the
relevant operating instructions):
an interval time of 1s (in menu>Interval measurements),
interface=printer (in menu>Data transmission),
"Send data to interface" (in "Type of data transmission").
3 For temperature compensation, set the unit [°C] at the measuring instruments. Two types of temperature
compensation exist:
- ATC (automatic temperature compensation) with a temperature sensor connected.
- MTC (manual temperature compensation) with no temperature sensor connected.
Note:
The pH or conductivity meters switch automatically, depending on the arrangement.
If the temperature unit at the pH meter or conductivity meter is set to [°C], the results "TpH" and "TCond" will
be converted to the temperature unit set in the instrument, i.e. either [°C] or [°F] . By contrast, if [°F] is set
at the pH or conductivity meter, no result will be calculated. "--" will be output in the results field.
Note
The conductivity units are [mS/cm]/ [μS/cm] (depending on the range) or [mS/m][μS/m] (depending on the
range). However, the results are expressed in [μS/cm]. If you wish to have the result displayed in [mS/cm] or
[mS/m][μS/m], it will be necessary to recalculate the result using the "Calculation" method function.
Colorimeter
- Lovibond
The Lovibond colorimeter can be used for extinction or transmission measurements. The wavelengths are
output in 5nm (in the range 420 – 710nm).
Note
A color measurement may take longer than 25s.
- Minolta colorimeters CM-5 / CR-5
The Minolta colorimeters can be used for transmission measurements (liquids).
Transmission data are supplied in 10nm increments within the spectral range 360 – 740nm.
A color measurement takes approximately 1s.
The measurements involve high-energy light flashes. For this reason, color scales are not offered for reflection
measurements in the crude oil industry.
Note
• The CR-5 colorimeter does not supply any spectral data.
• Calibration is possible directly at the colorimeter only. The USB link must be disconnected.
• "Illuminant" and "Observer" can be set in the "Configuration" method function. For more information, see

4.11.9 Tables & values
Navigation: Home > Setup > Tables & values
The instrument has tables and auxiliary values that can be used for the calculation of results (see also
"Results").
Installation and commissioning36 Density Meter Excellence
With measurements the raw data (e.g. temperature value, density) are delivered. This raw data is fed into the
relevant tables so that corresponding results can be displayed in the respective units.
Tables are always assigned to an application. The list can be sorted according to application.
There are two types of tables:
• METTLER TOLEDO tables:
These tables are included in the factory settings, they are only listed and can be neither edited, viewed nor
deleted.
• User-defined tables:
Tables are laid out in the form of a value table (X-Y). They can be created, edited and deleted.
Below is a description of how to create your own tables.
In addition to the tables, you can also administer the auxiliary values in setup. The auxiliary values can thereby
be used in formulas. By means of the method function "Auxiliary value", an auxiliary value from any desired
formula can be assigned raw data or calculated results.
4.11.9.1 Tables

Limits of error of the standard (with reference to the nominal
value).
5.1.6 Conditions and formulas
A logical condition can be defined to determine whether a particular method function should be executed based
on a result (true or false). The condition is in the format of a formula. An empty condition is interpreted as true.
Formulas can be used in various method functions. In formulas you can enter the calculated results Rx,
temperature-compensated values (TCx), tables, auxiliary values and raw data.
A formula can be structured, for example, as follows:
"CT[1]=0". This formula checks whether the first cell test of the method has failed ("0" stands for "false" and
"1" for "true").
The raw data of the method functions are indexed (e.g. CT[1], CT[2]). If an index is missing, [1] is used
automatically (CT=CT[1]).
Application example: The following method functions have been integrated in a method:
Method function: Cell test
Method function: Clean
0…0.001
"Interrupt if failed": Disabled
"Condition": Disabled
"Condition": Enabled
"Formula": CT[1]=0
Method function: Cell test
"Interrupt if failed": Enabled
"Condition": Enabled
"Formula": CT[1]=0
The following behavior was programmed with this sequence:
• If the first cell test was successful, the cleaning and the second cell test are skipped (conditions
"CT[1]=0").
• If the first cell test failed, the cleaning and the second cell test are executed (conditions "CT[1]=0").
• If the second cell test also failed, the execution of further tasks is interrupted (due to the activated setting
"Interrupt if failed"). In the current task, the "Fill" and "Measure" method functions are skipped.
Formula Editor
Navigation: Home > Methods/ Products> Methods > Method > Calculation
With the formula editor both numerical values and symbols can be entered. The symbols H, T and C are made
available when you select the 1 button in the formula editor.
If you touch H, the list of auxiliary values opens; T opens the table list; C opens the list of color scales for the
colorimeters. For colorimeters, it is possible to define whether measurements should be carried out in extinction
or transmission mode.
You can enter raw data manually or via insert via the button "Proposal". You will find the raw data in the
"Annex: Raw data".
Mathematical Functions and Operators
The following mathematical functions and operators can be used in formulas:
Configuration of methods and products48 Density Meter Excellence

Mathematical operators Logical operators
Addition + and AND
Subtraction - or OR
Multiplication *
Division /
Note
• Logical operators are only permitted within formulas of the subfunction "Condition".
• The use of mathematical operators (+, -, * and /) within a parenthetical expression is not possible.
Formula Syntax
- Brackets
There are three types of brackets that can be used in formulas:
• Round brackets "( )":
e.g. T[Table_name(d)] and mathematical operators ln(d)
• Curly brackets "{ }": Relation to the cell, e.g. d{DX}. if the cell is not specified, then the internal cell is used
as default.
• Square brackets "[ ]"
- Indexing of the raw result, e.g.CT[1]: corresponds to the result of the first method function "Cell test" (if the
method has several "Cell test" method functions)
- Table name T[Table_name()] , e.g. T[Brix_d_NBS(d)];
- Auxiliary value H[Auxiliary_value], e.g. H[Auxiliary_Value_1]
- Color results with subscale/wavelength COL[Color_scale()], e.g. COL[CIELAB(L)];
COL[x]; x= color scale without subscale
COL[x(y)]; x= color scale with subscale
COL[T..(z)]; z= spectral value
T= Transmission %, T= Transmission abs; T= Extinction
(The color scales shown can be selected in the formula editor using the C button; button 1 in the formula
editor calls up C.)
- Fixed abbreviations
The following abbreviations are defined:
D Internal density cell
RX Refractive index module
R1 ... Rx Results from the method function "Calculation"
TC1 … TCx Results from the method function "temperature compensation"
A, B, C, D, x, y Coefficients (A-D) and variables (x,y) can be used in formulas, e.g. Ax+B.
- Syntax examples
• Simple raw result: R1 = d
• Temperature compensation: R1 = TC1
Configuration of methods and products 49Density Meter Excellence
• Tables: R1 = T[Brix_d_NBS(d)]
The following values can be entered for tables:
- Internal tables: d, dRaw, dvisc, nD, TC
- User-defined tables: All generated analysis data
- Rules for color results
• Color scales with subscales:
The colorimeter sends up to four results (subscales) for each color scale. The subscales are inserted
between the round brackets. If only one color value is sent for a particular color scale, no round brackets
are needed, e.g. COL[Scale(Subscale)] or COL[Scale].
• Transmission and extinction:
The Lovibond colorimeter sends the results for all wavelengths, in increments of 5nm between 420 and
710nm, e.g. COL[Extinction(450)]. If you wish to define a wavelength between the results sent from the
colorimeter, this will need to be interpolated. "–" is displayed if the inputted wavelength is not within the
420 to 710nm range

5.1.7.12 Cell Test
Use this method function to verify the cleanliness and dryness of a cell, either before or after performing a
measurement, test, or adjustment.
A measurement of the empty (clean and dry) cell is performed, and compares the measured density to the
nominal air density under the current pressure conditions. A warning is shown if the difference exceeds the
defined tolerance.
Parameter Description Values
Tolerance Maximum permissible deviation of the measured air density from
the theoretical value [g/cm3].
Max. test duration Defines the maximum duration of the cell test in [s]. If the
measured value has not stabilized by this time, the cell test is
interrupted and is treated as failed.
Interrupt if failed
Active: the measurement receives the status Error if the cell test
fails. The task list is interrupted.
Inactive: the measurement proceeds, even if the cell test has
failed.
5.1.7.13 Temperature Compensation
Temperature compensation allows you to measure a sample at a temperature and then to output the measured
value at another temperature. This temperature compensation is used in the following cases:
• The measured value must for example be stated at 15°C, however the sample is too viscous at this
temperature. Therefore these samples must be measured at correspondingly higher temperatures so that
they can be pumped to the measuring cell and remain fluid there.
• For accelerated measurements. If the sample is delivered at 35°C for example and the measured value is
required at 15°C, the sample can be measured at 35°C and the measured value can be compensated to
15°C.
• If the required reference temperature is outside the range of the measuring instrument (e.g. 120°C), the
sample can be measured at 75°C and the result compensated to 120°C.
In order to use temperature compensation, the temperature dependency of the sample must be known (e.g.
density at various temperatures) or in the case of petrochemical products, their temperature dependencies in
accordance with ASTM-D 1250 are already stored in the device. The following tables are used (for crude oils,
refined products and lubricants):
• 53A, 53B and 53D for 15°C
• 5A, 5B and 5D for 60°F
• 59A, 59B and 59D, for 20°C
The aforementioned ASTM or API tables take as input values the readings taken from a hydrometer, which do
not however make allowance for the coefficient of expansion of the glass hydrometer. Therefore the measured
density cannot be directly used as the input value for these tables.
The measured values are converted to the desired temperature. The output value (TC) of this method function
can be used in the method function "Calculation".

You can start the product immediately or return to the product editor.
5.2.2 Linking Methods with Products
A distinction is made between two cases:
1. A product is created and linked with a method.
On linking of a product to a method (before saving the first time) the values are taken over from the linked
method.
2. A product has been previously created, the linked method is changed (relinking).
In this case only the methods for the relinking are suggested that agree with the currently linked method in
the configuration. After initial saving, the product parameters are not overwritten by the parameters of the
method.
For the measurement the product parameters are: such as e.g. Multiple measurements, Calculations
(Coefficients and result limits) are used and not the parameters of the corresponding method. The entries in
the method however remain unchanged.
Note
• When you start a product measurement, the parameters defined in the method are "overwritten" by the
product parameters.
• A maximum of 100 products can be defined.
• If no measurement methods have been defined on the device, no product can be created.
• Product ID’s can be used for barcode recognition.
• Several products can be linked to the same method.
• A product is always assigned to exactly one method.
• When a method is deleted, all linked products are also deleted.
• If a product is saved under a new ID, the values are retained in the product and are not overwritten by
standard values from the method.

7.3 Typical phases of density determinations
Density determinations usually include three phases.
• Fill the measuring cell and measure the density.
• Rinse the measuring cell to remove residue of the sample.
• Dry the measuring cell.
7.3.1 Fill the measuring cell
This chapter describes how to fill the measuring cell using a syringe. How to work with automation is described
in the following chapters.
•
There are two ways to fill the measuring cell using a syringe.
• Push samples into the measuring cell; suitable for viscous samples and degassing samples
• Pull samples into the measuring cell; suitable for non-viscous samples and non-degassing samples
Push samples into the measuring cell
• The sample is in the syringe(4). Users push the
sample into the measuring cell(1), through the waste
tube(2) and in the waste container(3).
• A clean syringe is needed for each sample.
• If some of the sample sticks to the opening for the
syringe(5), the next sample is contaminated.
Operation 73Density Meter Excellence
Pull samples into the measuring cell
4
1
2

5
• The sample is in the sample container(3). Users pull
the sample through the waste tube(2), into the
measuring cell(1) and then into the syringe(4).
• The sample is already analyzed, when it passes
through the opening with the syringe(5) that can be
contaminated.
• If the waste tube(2) is not clean and dry, the sample
can be contaminated.
7.3.2 Rinse the measuring cell
At the end of this phase, the residue in the measuring cell must have the following properties.
• Evaporate without leaving incrustations.
• Evaporate easily.
To clean the measuring cell, it has to be rinsed with one or two different cleaning solutions.
• Purpose of the cleaning solution1: Dissolve the sample, so that no sample is left in the measuring cell. If
the cleaning solution1 does not easily evaporate, a second cleaning solution must be used.
• Purpose of the cleaning solution2: Dissolves the cleaning solution1 and evaporates easily without leaving
any residue.
METTLER TOLEDO recommends the following cleaning solutions.
Sample Cleaning solution1 Cleaning solution2
Water, water based Deionized water Acetone, ethanol (100%)
Acids (concentrated) Water (flush the measuring cell with
Alkaline solutions (concentrated) 0.3…0.5% deconex solution Acetone, ethanol (100%)
Samples with fats or oily
components
Petrochemical samples, edible oils
and fats
Acetone, ethanol (100%)
plenty of water to remove the heat
from the reaction of water and acid)
0.3…0.5% deconex solution Acetone, ethanol (100%)
Toluene, xylene or petrol ether
mixtures
Room temperature: low-boiling
petrol ether mixture or acetone
Temperature > 30°C: hexane or
similar organic solvents
7.3.3 Dry the measuring cell
At the end of this phase, the measuring cell contains no residue and is ready for a new analysis or storage.
METTLER TOLEDO recommends to dry the ambient air that is pumped through the measuring cell using a bed
of desiccant (e.g. silica gel). The desiccant keeps dust and moisture back and reduces the risk that a hardly
visible layer of condensation forms on the walls of the measuring cell. The risk that moisture from the ambient
air condenses in the measuring cell depends on the relative humidity of the air and the difference between the
room temperature and the temperature of the measuring cell.
• The higher the relative humidity of the air, the higher the risk
• The farther the temperature of the measuring cell lies below room temperature, the higher the risk
Operation74 Density Meter Excellence
To check if the measuring cell is dry, users can measure the density of air or perform a cell test. If the measured
