3.2 Sensor Installation

Figure 4 on page 10 illustrates the installation overview for Solitax sc Models t-line, ts-line,

and hs-line for immersion in open tanks.

The maximum distance from the mounting surface to the sensor without the use of an
extension tube is 1.5 m (4.9 ft). When that distance exceeds 1.5 m (4.9 ft), one of the
following extension tubes is required and can be ordered separately:

• 1.0 m (3.28 ft) extension pipe LZY413

• 1.8 m (5.90 ft) extension pipe LZY414

To ensure a suitable measuring position, install the probe to the following conditions:

• The probe optical window must have a ground clearance of at least 30 cm (11.8 in.).

• Install the probe with the optical window facing (downstream) in the direction of the

flow to minimize the risk of fouling.

• Avoid installation sites where air bubbles are inconsistent. If this not possible, try
moving the probe slightly or adjusting its alignment to minimize the bubble effect.

• Protect the probe against the oncoming flow of large objects, such as branches or ice
and against flow surges.

• Avoid installing the probe with the optical window facing into direct light or facing a
highly-reflective surface.

Figure 4 Sensor Installation Overview

10

3.3 Pipe Installation

• Install the sensor in an up-flow pipe section for best results. Do not mount the sensor

in a down-flow pipe section.

• Mounting in a horizontal pipe section is acceptable if the sensor is fully immersed at all

times. Usually, mounting 90 degrees from the top of the pipe guarantees full
immersion. Do not mount on the top or bottom of a horizontal pipe section.

• Install the sensor in a pipe that is equal to or greater than 4 inches in diameter.

• Install the sensor at least 1.5 m (5 ft.) or three times the pipe diameter (whichever is

greater) downstream of pumps, valves, or pipe elbows.

• Install the sensor on the discharge side of a pump, if possible, with a dilution or flush

valve installed on the suction side of the pump.

• If the sensor is to be used to measure sludge with significant amounts of debris, install

it after a sludge grinding pump or after a pump with a grinding/comminuting unit in
front of it.

• Install the sensor within 7.8 m (25 ft.) of the controller with the standard probe cable.

Optional cable extensions can be added for a maximum combined distance of
100 meters (330 ft.).

Installation

• If the flange cannot be welded to the pipe due to incompatibility of materials between

the stud and the pipe, it is recommended that a stainless steel pipe section be
fabricated. Weld the flange onto the stainless steel pipe section and attach the
stainless steel section as a segment of the process pipe.

Select the cleaning interval (1, 5, 15 or 30 minutes; 1, 4, or 12 hours; 1, 3, 7 days)
Default: 12 hours

This is the interval between wiper cleaning of the sensor window. It is recommended to start with
a setting of 30 minutes. This time may be adjusted according to the application. If readings
continue to be accurate, try a longer interval. If not, shorten the interval.

This is a damping function. While the Solitax takes readings continually, it will average them
together over the period of the response time. Once the response time has elapsed, the
displayed reading, 4-20 outputs, and alarm status are updated. (0 to 300 seconds)
Default: 3 seconds

This is the datalog interval, with options from 1–15 minutes. Values logged are the average of
the all readings during the previous logging interval. The controller will hold approximately
360 days of readings for one sensor at 15 minute intervals, or 24 days at 1 minute intervals (and
proportional in between). Default:10 minutes

4.6.2 Calibration for Turbidity

Turbidity calibration requires the use of a Turbidity Standard Solution. The manufacturer
recommends the 800 NTU Turbidity Standard Solution (part of the calibration kit No.
57330-00). A zero-point calibration using deionized water is also recommended.

1. From the Main Menu, select SENSOR SETUP and press confirm.

2. Select the appropriate sensor if more than one is attached and confirm.

3. Select CALIBRATE and press confirm.

4. Select SENSOR MEASURE and confirm.

5. Place the sensor in the calibration cylinder with deionized water, mounting it with the

supplied clamp. The tip of the probe should be approximately 1-inch below the surface
of the water. Record the reading from the sensor measure display.

Operations

6. Select OFFSET. Multiply the reading obtained in step 5 and enter the value.

7. Select SENSOR MEASURE.

8. Rinse the outside of the StablCal

or debris adhering to the surface of the bottle. Gently invert both StablCal standard
bottles a minimum of 50 times. Remove the lid and seal from each bottle. Slowly (to
avoid creating bubbles) pour the contents of the bottles into the calibration cylinder.
Immediately place the tip of the probe into the positioning bracket in the calibration
cylinder. The tip of the probe should be approximately 1-inch below the surface
standard. Allow the reading to become stable on the SENSOR MEASURE screen.
Record the value (measured value). Calculate the factor. Refer to section 4.6.2.1.

9. Select FACTOR to display the corrected measurement.

4.6.2.1 Calculating the Factor

Operations

4.6.3 Calibration for Suspended Solids

Suspended solids calibration requires calibration to the actual sample. This optimizes the
compensation for the particle size and shape typical at a measuring site. It is best
performed by mounting the sensor as usual for normal measurement, and then grab
samples collected and evaluated by laboratory methods. While a single point calibration is
usually sufficient to provide accuracy, the SOLITAX does offer the ability to calibrate with
up to 5 calibration points.

1. From the Main Menu, select SENSOR SETUP and press confirm.

2. Select the appropriate sensor if more than one is attached and confirm.

3. Select CALIBRATE and press confirm.

4. Select CONFIGURE and confirm.

5. Select the number of points desired for calibration (the unit with linearly interpolate

values between calibration points). Select Factor for a single point calibration.

6. Mount the sensor as is during normal operation. Alternatively, place the sensor in the
calibration cylinder (or a container with dark, non-reflective walls) 2 inches of
clearance from the probe face with the probe face submerged by 1 inch or more.

7. Select SENSOR MEASURE and record the reading.

8. Immediately take a grab sample. Determine the total suspended solids using a

gravimetric method such as Method 2540 D in Standards Methods for the
Examination of Water and WasteWater.

9. Calculate the new factor. Refer to section 4.6.3.1 for single point (Factor) calibration.
Refer section 4.6.3.2 on page 18 for multiple point calibrations.

10. Select FACTOR and press confirm. The corrected measurement should be displayed.

4.6.3.1 For Single Point (Factor) Calibration

Calculate the new factor:

New Factor =

For example, if a sample measures 2.3 g/L using the SS sensor and the gravimetric value
was 2.0 g/L, the new factor would be calculated as follows:

New Factor =

Determined gravimetric value

measured value

2.0 g/L

2.3 g/L

= 0.87

4.6.3.2 Multi-point Calibration

1. Repeat steps 6–8 in section 4.6.3 on page 18 at different times to obtain different

measurements.

2. From the CONFIGURE menu, select the appropriate calibration point menu.

3. Enter the pairs of values for each reading, the target value being the laboratory

determined value, and the actual value being the reading that the SOLITAX produced
in step 5. The pairs should be entered in order from lowest values to highest.

Section 9 Warranty and liability

The manufacturer warrants that the product supplied is free of material and manufacturing
defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out within
6 months of purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including the lack
of assured properties as follows: all those parts that, within the warranty period calculated
from the day of the transfer of risk, can be demonstrated to have become unusable or that
can only be used with significant limitations due to a situation present prior to the transfer
of risk, in particular due to incorrect design, poor materials or inadequate finish will be
improved or replaced, at the supplier's discretion. The identification of such defects must
be notified to the supplier in writing without delay, however at the latest 7 days after the
identification of the fault. If the customer fails to notify the supplier, the product is
considered approved despite the defect. Further liability for any direct or indirect damages
is not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to be
performed within the warranty period by the customer (maintenance) or by the supplier
(servicing) and these requirements are not met, claims for damages due to the failure to
comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be made.

Consumables and damage caused by improper handling, poor installation or incorrect use
are excluded from this clause.

The manufacturer process instruments are of proven reliability in many applications and
are therefore often used in automatic control loops to provide the most economical
possible operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the control
loop such that a malfunction in an instrument results in an automatic change over to the
backup control system; this is the safest operating state for the environment and the
process.
