ViSolid®700 IQ (SW) Overview

1.4 Features of the ViSolid®700 IQ (SW)

Total suspended solids

measurement

The measurement of the total suspended solids in aqueous media with

the ViSolid

700 IQ (SW) is carried out as a scattered light measurement. This records the suspended proportion of total suspended solids (TSS).

Ultrasound cleaning

system

The ultrasound cleaning system ensures low maintenance and longterm reliable measurement operation. The ultrasound source integrated in the sensor excites the front face containing the measurement windows to oscillations in the ultrasound range. The resulting movement of the surface prevents the growth of pollution right from the start and, thus, ensures reliable measured values during continuous operation.

AutoRange function Within the enormously large measuring range (0 - 40000 mg/l SiO2

and 0 - 40000 mg/l TSS depending on the measured material), the AutoRange function selects the optimum resolution for the respective measured value.

SensCheck function This monitoring function that is integrated in the sensor is used to

continually check the sensor function and to register any malfunctions caused by the measuring medium. The correct operation of the ultrasound cleaning system is also continuously monitored.

3.3 Installation

3.3.1 General information

The measuring principle of the ViSolid

700 IQ (SW) (scattered light measurement) places specific requirements on the measurement location and on the installation of the sensor.

If there is a low level of total suspended solids (< 2000 mg/l SiO2 or < 1000 mg/l TSS), infrared light penetrates deep into the sample. Thus, the measuring environment can have a significant effect on the measured value displayed. Light that is reflected or scattered by the ground or wall can strike the detector in the sensor and, thus, simulate an increased level of total suspended solids.

Scattered light can be kept away from the measurement windows to a great extent by favorable positioning of the sensor. Therefore, an optimum installation position is particularly important for the measurement of lower values of total suspended solids.

Note

Always maintain a distance of at least 10 cm from the ground and wall.

The following factors affect the measurement of the TSS contents:

 Inclination of the sensor (see section 3.3.3)

ba76040e02 07/2013

3 - 1

Commissioning ViSolid®700 IQ (SW)

 Sensor orientation around its longitudinal axis (see section 3.3.4)

 Distances from the ground and wall (see section 3.3.5)

 Light-colored, heavily light-scattering surfaces in the measuring

vessel (e.g. vessel inner surfaces) or in the measuring environment.

 Unfavorable geometry of the measuring vessel or unfavorable

positioning of the sensor in the measuring vessel.

 Spatial proximity of two optical sensors.

 Very bright ambient light at the measuring location, e.g. direct

sunlight in the open channel

3.3.2 Flow direction

Generally, in flowing media, the measurement window should be clearly pitched towards the flow (angle of incidence approx. 20 to 45 °).

Exception:

If there is a high proportion of foreign bodies with fibrous or flat profiles such as, e.g. hair, twines or foliage, it can be advantageous to tilt the sensor in the direction of flow so that the measurement window is turned away from the flow.

Note

If there is a low level of total suspended solids (< 2000 mg/l SiO2 or < 1000 mg/l TSS), the effects of the measurement environment can simulate a higher content of total suspended solids. The effect of the measurement environment can be reduced by ensuring the optimum conditions (see section 3.3.1).

The following graphic indicates the minimum distances of the measurement windows to the ground or wall, which must be observed. The effect of the distances on the measured value has been determined for various wall materials (aluminum, black plastic) in the case of a sensor placed vertically to the wall in drinking water or water with 1000 mg/l SiO2.

ba76040e02 07/2013

Fig. 3-3 Effect of ground and wall distances on the measurement of TSS

Note

At low levels of total suspended solids, a minimum distance of at least 10 cm must be kept from the ground or wall.

Note

If an optimum installation is not possible due to the structural conditions at the measuring location (e.g. in narrow pipelines), the effects of the measurement environment can be compensated by user calibration (see section 4.2.4).

ViSolid®700 IQ (SW) Measuring

4 Measuring

The ViSolid®700 IQ (SW) measures the light scattered and reflected by the total suspended solids in the measuring medium. The level of total suspended solids that corresponds to the amount of light measured is displayed. As different suspended solids scatter and reflect light in different ways, the display of a suspended solid contents in mg/l must be referred to a standard. A factory calibration to SiO2 is stored in the sensor.

4.1 Measuring operation

1 Immerse the sensor in the measuring medium.

2 Read the measured value on the terminal of the IQ S

ET system.

ENSOR

Note

Large temperature differences between the sensor and measuring medium can falsify the measurement result. Thus, as a precaution during commissioning, wait for 15 minutes before using the measured value.

Note

The allowed temperature of the measuring medium is 0 ... 60 °C. The ultrasound cleaning system automatically switches off if the temperature of the measuring medium increases to more than 60 °C. When the temperature drops below 60 °C, it switches itself on again. Switching off at temperatures above 60 °C prevents any overheating, for example if the minimum immersion depth of the sensor is not maintained.

4.2 Calibration for TSS measurement

4.2.1 General information

Why calibrate? The following factors can change with time and affect the measurement

results:

 the optical characteristics, e.g. color and particle size, and the

density of the measuring medium (e.g. dependent on the season)

 the conditions at the measuring location (e.g. due to growing

deposits on the ground and walls)

The effect of the measurement environment can be reduced by ensuring the optimum conditions (see section 3.3.1) and can be compensated by a user calibration (see section 4.2.4).

When to calibrate? A new calibration is required if there is any change of the

characteristics of the measuring medium or any change of the environment at the measuring location.

How is a calibration

carried out?

Note

Calibration data that are entered are stored in the controller and, thus, assigned to the measuring location (and not the sensor). Thus, if the sensor is replaced, no new calibration is required.

The actual level of total suspended solids of your measuring medium is determined by a reference measurement (e.g. gravimetric according to DIN 38414).

If the reference measurements do not deviate from the optically

determined level of total dissolved solids of the ViSolid

700 IQ (SW),

the sensor is already optimally adapted to the measuring situation.

If the reference measurements deviate from the optically determined

level of total dissolved solids of the ViSolid

700 IQ (SW), a calibration

is required.

The following calibration options are available:

 Calibration by adapting the Correction factor setting

if the values displayed with Default calibration deviate from the actual values by a specific factor

 Performance of a User calibration

if the values displayed with Default calibration and Correction factor no longer agree with the actual values

Influences If there is a low level of total suspended solids (< 2000 mg/l SiO2 or

< 1000 mg/l TSS), the effects of the measurement environment can simulate a higher content of total suspended solids. The effect of the measurement environment is minimized by exactly observing the installation position (see section 3.3.1).

If an optimum installation is not possible due to the structural conditions at the measuring location (e. g. in narrow pipelines), interference effects can be compensated by a User calibration (see section 4.2.4).

4.2.3 Correction factor

The setting of the Correction factor provides a simple option for adapting the calibration to the current conditions.

With the Correction factor setting you correct the measured value and have it indicated on the display.

A change of the Correction factor setting is practical if the measured

values of the ViSolid

700 IQ (SW) are generally too high or too low in

comparison to reference measurements by a specific factor.

8 Set the new Correction factor in the Calibration data menu (see

section 3.5.3).

Note

The Correction factor setting affects each TSS measuring mode and all calibration data. Also, if there is a change of the measuring mode or calibration data, the Correction factor is retained. Therefore, after every change of the settings in the Calibration data menu, check the Correction factor.

4.2.4 User calibration

The displayed values of total suspended solids are calculated with the aid of the stored calibration data. In the mg/l TSS measuring mode, the value mg/l SiO2 marked with "#" is displayed as the secondary measured value.

The determination of the calibration value pairs is carried out by reference measurements according to an independent procedure. At the point of time of the calibration, the measuring medium should be in a state representative of the later measurement (type and amount of total suspended solids, coloration, etc.). The results from the calibration

are manually entered in the setting table of the ViSolid

700 IQ (SW).

Graphs of the value pairs Explanations

Form 1:

The graph has a gradient > 0 at every point. A calibration is possible for the whole range.

Form 2: The graph has a gradient > 0 at every point. At very low levels of TSS, the effect of the measurement environment leads to slightly increased values of SiO2. A calibration is possible for the whole range.

Form 3: The graph has a gradient < 0 in the range of smaller levels of TSS. The effect of the measurement environment leads to greatly increased values of SiO2 in the range of smaller TSS below the point (A). A calibration is only possible in the range TSS > A.

ba76040e02 07/2013

Form 4: The graph has a gradient < 0 in the range of greater levels of total suspended solids. A calibration for matrix type 1 is only possible in the range of TSS < B. For measurements in the range of TSS > B, select matrix type 2.

4 - 7

Measuring ViSolid®700 IQ (SW)

Note

A measurement of the total suspended solids will deliver ever more accurate measurement results the closer the composition of the measuring medium corresponds to the status at the time of the calibration. If there is a fundamental change of the characteristics of the sample, a new calibration may be necessary.

Procedure of the

calibration

1 Bring the sensor into the measuring position.

2 In the setting table of the TSS sensor, select the

mg/l TSS measuring mode and the AutoRange measuring range (see section 3.5.3).

3 Switch to the measured value display with <M>.

4 When the measured value is stable, read the SiO2 value

(marked with "#"), convert it into the unit (mg/l) if necessary, and note it down.

5 Take a sample as close to the same time as the SiO2

measurement as possible and as close to the sensor as possible.

6 Determine the level of total suspended solids of the sample

according to a reference procedure (e.g. gravimetric according to DIN 38414) and note it down together with the measured value of SiO2 as the TSS/SiO2 value pair in mg/l.

Note

At least one value pair and a maximum of eight value pairs can be entered for a valid calibration. Keeping to the descending order of values is very important. Not keeping to the order will result in a calibration error.

4 - 8

7 For a multi-point calibration:

Repeat the determination of the value pair for various concentrations of the sample.

Note

Samples of different concentrations of total suspended solids can be obtained from the sample taken by:

 diluting it with water

 depositing the total suspended solids and decanting off the

remaining water

Before measuring the samples, make sure that the total suspended solids are actually in suspension.

8 Sort the value pairs in descending order and, if necessary,

enter them in a table and diagram (see chapter 10).

Note

Below the smallest value, the calibration curve is extended to the zero point and, above the largest value, it is extended to the end of the measuring range.

9 Check the form of the calibration curve.

If the calibration curve corresponds to form 3,

 change the conditions at the measuring location and

determine the calibration values again or

 do not carry out any measurements in the range below the

turning point (A).

10 In measuring mode with matrix type 1:

If individual calibration values lie outside the measuring range,

Entering the Calibration

data

 change the conditions at the measuring location and

 select measuring mode for matrix type 2

Note

The entry of calibration values that exceed the measuring range leads to a calibration error. The size of the measuring range is dependent on the selected measuring mode (matrix type) (see section 3.5.3).

all components (see system operating manual)

 via an automated query

– of a superordinate process control (e. g. when connected to the

Profibus)

– of the IQ Data Server (see operating manual of the

ENSORNET software pack)
