5 Application Program Ext-Cell


[Config] [Appl-Prog] [Ext-Cell]

This application program determines density and/or concentration of a sample filled into an external density cell (DMA 512P, DMA 602, DMA 401, DMA HPM). For the DMA HPM, also the measuring temperature can be displayed. It enables the automatic calculation of the adjustment constants DA and DB, storage of 256 different sets of transducer constants and storage of 256 sets of concentration formula coefficients.

It is replacing the EXTCLL21 application program of the mPDS 2000 V2.

Necessary equipment:

• One external measuring cell (DMA 602, DMA 512P, DMA 401 or DMA HPM).

• One interface for external cells (for DMA 602 and DMA 512 P)

• mPDS 2000V3 evaluation unit

• Miscellaneous programs group "D"

To check, which application software is stored on the mPDS 2000V3, press the " " key. The version of the application program is shown on right side (e.g. "…D01.00")

Measuring ranges:

Important:The mPDS 2000V3 is a process evaluation unit and has to be installed into a separate housing or switch board.

5.2 Product Selection

Different products can be selected via submenu (Prod-No) or an external product selector switch. Valid product numbers are: 0 ... 255. The current product number is shown in the measuring window (E.G. "# 005"). During measurement of a particular product, the product number must be set to the number (0 … 255) which has been chosen initially.

5.3 Adjustment of the External Density Cell

The external cell has to be operated at constant temperature and constant pressure using an external thermostat. To enable a density measurement the external cell has to be adjusted using two different samples of known density (2 standards), usually air and distilled water for temperatures between 0 and 80 °C. For the adjustment at higher temperatures, air and a liquid of precisely known density at adjustment temperature has to be used. The boiling point has to be considerably higher than the adjustment temperature. For temperatures up to approximately 130 °C, n-Nonane may be suitable, for temperatures up to 150 °C n-undecane may be useful.

Important:The program does not check the plausibility of the customer specific polynomial. Values higher than 100% and lower than 0% are possible using wrong or invalid coefficients.

Select a product number using menu [Prod-No]

The following equation is used to determine density from the period of oscillation of the measuring cell:

Apparatus constants DA and DB have to be determined by measuring the periods of 2 standards of known density at measuring temperature. DA and DB are only valid for this temperature and pressure.

The program contains the feature for the automatic determination of constants DA and DB for 256 different temperatures and pressures.

The program contains the feature for the automatic determination of constants DA and DB for 256 different temperatures and pressures.

Strictly follow the steps below:

1. Select a product number 0 ... 255 via submenu [Prod-No]

2. Fill density standard1 of known density. If air is used as density standard 1 rinse and dry the cell properly.

3. Wait until the period of oscillation is absolutely stable. The second digit after the comma should be constant. Note down the period in the adjustment report (appendix).

4. Enter the density of standard 1 to product parameter [Density1] via submenu [Prod-Spec] - [Parameter]. Note down the density of standard 1 into the adjustment report (e.g. 1.204 E-3, density of air at 20 °C. See also Chapter 5.7).

5. Set product parameter [Control] to "1" via submenu [Prod-Spec] - [Parameter]. The program automatically stores the current period in product [Period1] and sets [Control] to "2".

6. Fill the second standard of known density. For 20 °C distilled water is commonly used.

7. Wait until the period of oscillation is absolutely stable. The second digit after the comma should be constant. Note down the period into the adjustment

8. Enter the density of standard 2 to product parameter [Density2] via submenu [Prod-Spec] - [Parameter]. Note down the density of standard 2 into the adjustment report. (e.g. 9.98204E-1, density of water at 20 °C. See also chapter 5.7.)

9. Set product parameter [Control] to "3". The program automatically stores the current period in product parameter [Period2] and sets parameter [Control] back to "0". The program automatically calculates the new DA and DB constants. The new values are stored as apparatus/transducer constants 'DA' and 'DB'. In addition product parameter [Const-A] is set to 'A' and product parameter [Const-B] is set to "DB".

10. Now the mPDS 2000V3 reads the correct density at the temperature and pressure used during the adjustment.

5.4 Concentration Calculation using Customer Specific Polynomials

After having adjusted the external cell at a particular temperature you may enter a concentration polynomial valid for a particular sample at this temperature.

The following polynomial is built-in:

concentr = KA + KB * dd + KC * dd2 + KD * dd3 + KE * dd4 + KF * dd5+ KG * dd6 + KH * dd7

KA ... KH ....................... polynomial coefficientsconcentr ........................ concentration in %dd ………………... ......... density

The coefficients have to be stored by the user for each product separately:

Select the product number you have been using during the adjustment of the external cell and enter the coefficients as follows via submenu [Prod-Spec] - [Parameter]: [KA], [KB], … [KH]

Important:Do not change the product number as long as you measure at this temperature and pressure. Otherwise you will get wrong density and concentration results. The adjustment must be carried out for each product number separately using proper standards with known densities at measuring temperature and pressure.

6 Control of Density (IBM-BFE)


[Config] [Appl-Prog] [IBM-BFE]

This application program is used to keep the density of a 2 component liquid constant. Because during the process operation water evaporates, water will be added automatically after the density overshoots a selectable target density. The Anton Paar measuring system for the in-line monitoring of density consists of the following components:

• DPR or DPRn transducer


• Program group miscellaneous (EXTCLL, …)

The IBM-BFE application program of the mPDS 2000V3 replaces the IBMBFE22 software of the mPDS 2000 V2.

Measuring range:

Density: 0 ... 3 g/cm³

Temperature: Depending on the used DPR(n) transducer and calibration range

A90IB16 27





Density True density at measuring temperature in [g/cm³]

CompDens Density at reference temperature in [g/cm³]

CloseTime "Closing time" of the digital output (control) DO1 in [seconds]

Target Target density at reference temperature in [g/cm³] (default: 1.04998)

DO1-Ctrl State of the digital output (control) DO1 0 … low, 1 … high

Deviation Last deviation between target and current density at reference temperature in [g/cm³]

Compensated density < 0

The calculated density at reference temperature is below 0. The program set this value to '0' and generates an error message. Check the coefficients Ref-Temp and K1,K2,K3.

P-factor = 0 The application parameter P-factor = 0. Enter the required number. (see page 20)

Cycle = 0 The application parameter Cycle = 0. Enter the required number. (see page 20)

Target density = 0

The application parameter target-D = 0. Enter the required number. (default: 1.04998)

Tolerance = 0 The application parameter Tolerance = 0. Enter the required number. (default: 1e-4)

Wrong transd. type

Only DPRn and DPR are allowed as transducer types for this application program!

6.3 Hints for Putting into Operation

Putting the instrument into operation is explained in the mPDS 2000V3 Instruction manual. Additional functions for the application program are explained below.

Special wiring and scaling of inputs and outputs

The regular alarm function using the 2 relays of the mPDS 2000V3 can still be used for additional purposes.

Important:All the procedures listed in this section should only be carried out by authorized personnel!

DO1 This digital output is 'high' during the closing time if the measured density at reference density is greater than the target density at reference temperature + Dead-zone

DO2 This digital output is high if the density at reference temperature exceeds the target density +/- Tolerance.

A90IB16 29


Transducer types: Menu [Config] [Transd] [Type]


Control function

The program calculates the CloseTime using the density at reference temperature at the beginning of the control cycle. If this density at reference temperature is greater then the target density, digital output 1 (DO1) is high for a certain time thus controlling the adding of water.

The CloseTime is calculated in the following way:

CloseTime = abs [P * ( TARG - DCOMP)] = abs [P * DEV.]

P application parameter P-factorTARG application parameter Target DCOMP CompDens = current density at reference temperature DEV. Last deviation between target and current density at reference

DPR, DPRn

P-factor P-factor for control (default: 120000)

Dead-zone Zone for no control (default: 2e-5 g/cm³)

Cycle Control cycle time in seconds (default: 20 seconds)

Delay Delay for starting the control at initial start up in minutes. (default: 2 minutes)

Target-D Target density at reference temperature (default: 1.04998 g/cm³) The display value 'Target' is set equal to application parameter Target-D.

Tolerance Allowed density tolerance from target density before activating the alarm output DO2.(default: 1e-4 g/cm³).

Ref-temp Reference temperature for the temperature compensation formula (default: 27 °C): CompDens = Density + K1*(Temp - Ref-temp) + K2*(Temp - Ref-temp)² + K3*(Temp - Ref-temp)³

K1 K1 … linear coefficient for temperature compensation of density. (default: 3.4971e-4)

K2 K2 … quadratic coefficient for temperature compensation of density. (default: 2.2847e-6)

K3 K3 … cubic coefficient for temperature compensation of density. (default: 0)

30 A90IB16


EXAMPLE: (using default values)

CloseTime is calculated as follows:

CloseTime = abs [120000 * (1.04998 - 1.05005)] = ∼8 seconds

The digital output 1 (control) is "high" for 8 seconds within the control cycle time. After 20 seconds CloseTime is calculated once again.

Alarm function

The application program uses the digital output 2 (DO2) as a special alarm output.

The alarm limits are derived from the following application parameters:

Lower limit = Target - Tolerance Upper limit = Target + Tolerance

If one of the limits is exceeded the digital output 2 gets "high". Otherwise this output is "low".

Important:• CloseTime is calculated at the beginning of each control cycle. • If CloseTime is greater than the cycle time CloseTime is set to the cycle

time.• If the deviation between target and last density at reference temperature

is smaller than the application parameter Dead-zone then the control output is low and CloseTime is set to "0".

• The digital output 1 (control) is only closed if the current density at reference density is greater than the target density at reference density.

Control Cycle time 20

Current CompDens 1.05005 g/cm³

Target 1.04998 g/cm³

P-factor 120000

Hint:The mPDS 2000 set the digital output 1 (control) to "high" for CloseTime +/- 1 seconds. There is an uncertainty of about 1 second. The shorter the cycle time the greater the relative influence of this uncertainty.

7 Application Program Milk-Fat


[Config] [Appl-Prog] [Milk-Fat]

This application program determines several concentration values of milk using application/product-specific polynomials. The customer is able to enter the coefficients of the polynomials.

Necessary equipment:

• DSRn transducer or SPRn/SPR Transducer+DTR transmitter


• Miscellaneous programs group "D" To check, which application software is stored on the mPDS 2000V3, press the " " key. The version of the application program is shown on right side (e.g. "…D05.00")

Measuring ranges:

Concentration: Depends on the validity of the used polynomials

Temperature -25 ... + 125 °C (depends on the validity of the used polynomials and on the calibration range of the transducer).

Important:The software does not check the plausibility of the concentration values. If the calculated concentration is below 0 it is set to '0' and a warning message is displayed.

A90IB16 33




7.2 Product Selection

Different products can be selected via the submenu [Prod-No] or an external signal from PLC or via a product selector switch. Valid product numbers are: 0 ... 255. The current product number is shown in the measuring window (e.g. "# 005").

During measurement of a particular product, the product number must be set to the number (0 … 255) which was set when it was adjusted initially.

7.3 Adjustment of the 3 Concentrations using Offsets

The 3 concentrations (Fat, Solids, Fat-2) can be adjusted using constant offsets.

1. Assign a product number (1...255) to the product flowing through the trans-ducer and select this product number in the of submenu [Prod-No].

2. Compare the displayed concentrations (Fat/Solids/Fat-2) with the results of several samples analysed in the laboratory. Calculate the mean deviation.

3. Correct the mean deviation. To achieve the best accuracy, it is important notto correct the reading after each comparison with the laboratory.

4. In submenu [Prod-Spec] [Parameter] select the parameter [Fat-off] / [Solid-off]/[Fat-2-off]. Add the calculated deviation to the displayed value of the parameter [Fat-off] / [Solid-off]/[Fat-2-off] and enter the new offset.

Fat Fat content in [%]

Solids Solids content in [%]

Fat-2 Fat content 2 (from global formula, not product specific)

SNF-AI1 SNF … Solids Non Fat from external DTR transmitter connected to AI#1.

34 A90IB16


e.g. Fat/mPDS 2000 3.45 Fat/Lab 3.55 Fat-off/old 0.0 Mean deviation = Fat/Lab - Fat/mPDS 2000

= 3.55 - 3.45 = 0.10

Fat-off/new = Fat-off/old + mean deviation = 0.0 + 0.10 = 0.10

Fat(adjusted) = 3.55


7.5 Hints for Putting into Operation

Putting into operation is explained in the mPDS 2000V3 instruction manual. Additional functions of the application program are explained below.

Fat < 0 Solids < 0 Fat-2 < 0

The calculated values of Fat/Solids/Fat-2 lie below '0'. The program sets these values to '0' and generates the corresponding error messages. Compare the transducer constants (submenu: [Config] [TRANSD] [Dens-Cons], [Temp-Cons] and [Svel-Cons]) with the values on the enclosed DSRn data sheet. Check the entered formula coefficients. Note that most coefficients are product-specific.

Wrong transd. Type This application program requires a DSRn or SPR(n) transducer. Check the selected transducer type.

Important:All the procedures listed in this section are to be carried out by authorized personnel only!

1. Determining of the average concentrations To smooth fluctuating measuring values, the mean value of the last 0 ... 99 values can be displayed instead of the actual values. The filter size in seconds is stored in the application parameter "filter" [Config] [Appl-Prog] [Filter]. Values of 0 … 99 correspond to a filter size of 0 … 99 seconds.

2. Entering the polynomial coefficients for the calculation of concentrations This application program uses 3 polynomials of higher order to calculate the concentrations of a milk.

AI#1 Terminals 18, 19 A 4-20 mA signal from an optional DTR transducer. The signals corresponds to SNF (Solids Non Fat). The format and the scaling must match the DTR settings.
