Product Description
The AMI Turbiwell is used to measure turbidity in potable water,
surface water and effluents.
For the measurement of turbidity in pure water in water steam cycles a variant on steel panel with digital flow meter is available.
The turbidimeter is also suitable for the measurement of other liquids of which the turbidity correlates with the concentration of a
suspended solid or an emulsified liquid, e.g. oil in water.
See chapter ppm Calculation, e.g. “Oil in water”, p. 40 for details.
The instrument is available in two different models which only differ
upon the light emitting diode:
 Turbiwell 7027: with an IR LED according to ISO 7027
 Turbiwell W/LED: with white light LED; approved, alternative
method to US EPA 180.1
The two models are available in different configurations:
 Automatic or manual drain valve
 Sample degasser (option)
 deltaT flow sensor (option)
 On small panel with remote transmitter
 On steel panel with flow meter
Signal
Outputs
Two signal outputs programmable for measured values (freely scalable, linear or bilinear) or as continuous control output (control parameters programmable).
Current loop:
0/4–20 mA
Maximal burden:
510 
Third signal output available as an option.
Relay
Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with automatic hold function. Both contacts can be used as normally open
or normally closed.

AMI Turbiwell
Product Description
Measuring
Principle
Nephelometric system: A water sample colored by dissolved substances is a homogeneous system that only attenuates radiation
passing through the sample. A water sample containing undissolved substances attenuates radiation and, additionally, the insoluble particles scatter the radiation unequally in all directions.
To obtain the turbidity value of the sample, the diffuse radiation is
determined at an angle of 90°.
The AMI Turbiwell uses a non-contact turbidimeter to avoid fouling
of optical surfaces.
The light beam of the LED (Light Emitting Diode) impinges the water surface and is refracted. In an angle of 90°, the detector measures the incoming, scattered light.

The barrier avoids measurement errors due to light reflections.
Depending on the model the LED emits light with a wavelength of
860 nm (near infrared LED) according to ISO 7027 or in the range
from 400 to 600 nm (white LED) as an approved alternative method
to US EPA 180.1.
On-line
Operation
10
The sample enters at the sample inlet [F]. The constant head [A]
guarantees a constant sample flow into the measuring chamber [E],
and air bubbles will be removed. Excess sample overflows directly
into waste 1 [H]. The sample flows into the measuring chamber, fills
it, and then flows via overflow [D] into the waste 1. The LED beam
impinges continuously on the calm surface.

If the optional sample degasser is used, the sample first flows
through this device before entering the measuring chamber.
The drain valve [G] is used to empty the measuring chamber for
maintenance work like cleaning the measuring chamber or perform
a verification.
Verification
For the verification, two different verification kits (Low and high turbidity) can be used. The kits are available as an option.
Calibration
The AMI Turbiwell is factory calibrated therefore it is not necessary
to calibrate this instrument. The emission intensity of the LED is
monitored by an external photodiode. A loss of intensity due to aging will be automatically compensated. As a consequence, no additional calibration must be done.
To meet the requirements of some public authorities it is possible to
calibrate the instrument with a formazine standard.

before it can be used for a verification.
Verification
Never perform before the run-in time is over and before the measuring value is stable.
May be done to prove the instrument functions.

deltaT Option
As an option a deltaT sensor for flow measurement can be installed. This sensor is intended for the flow measurement of effluent water. The large diameter of the measuring pipe prevents
clogging of the sensor.
The flow measurement is based on the measurement of the temperature difference between the sensor input and output. For this
purpose temperature sensors are installed at the input and the output of the deltaT sensor. At the output an additional heating resistor
is installed. The heating resistor is cooled down as long as the sample flows through deltaT sensor. Depending on the sample flow rate
a certain temperature difference (deltaT) between the input and
output results. If the sample flow is too low or stopped, the temperature of the heating resistor rises up and a flow alarm is triggered.
For a reliable flow measurement a laminar flow through the deltaT
sensor is essential. To ensure a laminar flow, the sample inlet of the
deltaT sensor must not be restricted; e.g. any fitting which creates
turbulences.

3.5.5
Adjust the deltaT Flow Sensor
The accuracy of the flow measurement depends on the ambient
temperature of the location where the deltaT sensor is installed.
The deltaT flow sensor is factory calibrated at 20 °C (± 20 % accuracy). If the temperature is higher or lower, the deltaT flow sensor
can be adjusted.
To adjust the deltaT sensor proceed as follows:
Run in
Determine the
flow rate
Adjust slope
After installation let the sensor run-in for at least 1h.
1
Put the sample outlet of the instrument for 10 min. into a measuring cup with a sufficient volume.
2
To get the flow rate in l/h, calculate the amount of water contained in the measuring cup with factor 6.
 The flow rate in l/h results from the multiplication of the
amount of water after 10 min by 6.
1
Navigate to <Installation/Sensors/Flow>, choose <Slope> and
press [Enter].
2
If the calculated flow rate is higher than the displayed flow rate
increase the Slope value.
3
If the calculated flow rate is lower than the displayed flow rate
decrease the Slope value.

Instrument Setup
After the analyzer is installed according to the previous instructions,
connect the power cord. Do not switch on power, yet!
Open the sample flow and wait until the measuring chamber is full
and the sample flows via overflow into the waste.
Switch on power.
First, the analyzer performs a self test, displays the firmware version and then starts normal operation.
Program all parameters for external devices (interface, etc.). Set all
parameters for instrument operation (limits, alarms).
If the turbidity value is very low (< 1 FNU/NTU) rinsing may take
several hours (~24h). Rinse till a constant value is displayed.
Calibration, Matching and Verification
If required by regulating agency, calibration at customers site may
be performed. This calibration is performed with a specified formazine standard. It does not change the zero point defined at factory calibration but only the slope of the calibration line, see
Calibration, p. 52 for details.
The calibration is accepted if the deviation is less than 25% of the
factory calibration. The long term stability of the AMI Turbiwell can
be checked with a verification kit which has to be matched to the
latest calibration. To create a matched verification kit the following
steps are necessary:
1
Factory calibration or if required: calibration at custom site
(max. deviation ± 25% of factory calibration).
2
Verification kit matching (max. deviation ± 25% of calibration).
3
Verification with matched verification kit (max. deviation ± 10%
of nominal value).
Matching a Verikit is necessary to measure and save the specific
absorption of a Verikit. The measuring value is stored and each
verification is based on this value. With a matched Verikit you can
perform periodically a verification which has to be within 10% of the
reference value.
Perform a verification with a Verkit, see Verification, p. 59 or a wet
verification, see Wet Verification, p. 61, after running-in time to
prove the instrument functions correctly.

ppm Calculation, e.g. “Oil in water”
NOTICE: If ppm is chosen, the matching and verification
function is not available.
General
The turbidimeter „Turbiwell“ is also suitable for the measurement of
other liquids of which the turbidity correlates with the concentration
of a suspended solid or an emulsified liquid. In such applications,
the turbidity is normally displayed in ppm. Not recommended for
drinking water applications.
A submenu allows the user to perform a calibration of such processes.
The calibration line is defined by 2 points: Zero-point and a scale
point (slope).
For the determination of the zero point, a sample without the opacifier (x = 0) must be supplied to the Turbiwell. The average value
over a defined time period is automatically saved as the zero point.
For the determination of the slope, the Turbiwell must be supplied
with a sample with a known concentration of turbidity material
(opacifier). The concentration of the opacifier must be entered into
the transmitter (i.e. 2.5 ppm). The average value over a defined
time is automatically saved as slope (scale point).
The calibration line is calculated from this data.
NOTICE: Two restrictions regarding this calibration method
must be considered:
•
The reading is only valid if the zero does not change. This
means that the background turbidity which is caused by
different properties or different suspended solids must be
constant!
• In general, the correlation of the displayed value (ppm) and
content of the opacifier is only approximately linear in a
limited range. Due to that fact the sensitivity is strongly
dependent on the chosen concentration (scale point). If the
scale point is chosen so that it is close to a limit value or a
control point (i.e. setpoint), the error caused by non-linearity
in this range, can be minimized.
It must also be taken into consideration that the turbidity of a sample does not only depend on the concentration of the suspended
solid or emulsified liquid, but also on the drop-size, respectively,
particle-size distribution function. This property of the sample
should not differ substantially.

Considerations
Activate ppm
calculation
Considerations for a reliable measurement:
 The sample must always have the same grade of homogenization to receive quantitative results. Adequate homogenization can be achieved with a centrifugal or a gear pump.
 The distance and the time period from sampling to measurement should be short enough to ensure that the drop size
does not essentially change.
 It is not possible to avoid the accumulation of a thin layer of oil
on the walls of pipes, fittings and measuring chamber when
measuring samples with permanent oil content. If the oil concentration in the sample decreases, part of the oil layer is removed. This is a very slow process so it can take a long time
till the actual concentration is displayed correctly. In the case
of measurements with varying concentrations, a (automatic)
cleaning of the sampling system is recommended, especially
when low concentrations need to be determined with a high
accuracy.
 The solubility of most oils in water is very low but depending
on the type of oil, several ppm are dissolved in water. This
dissolved oil cannot be detected by turbidimeters. The value
of the dissolved part of the oil must be added to the undissolved part to determine a limit value correctly.
 The sensitivity varies in different oils. A typical comparative
value for 1 ppm of oil is 0.5 FNU/NTU.
To activate <ppm calculation> navigate to menu <Installation>/
<Sensors>/<Dimension>.
Choose ppm, press [Enter], press [Exit].
Choose <Yes> and press [Enter] to save.

Process
calibration
42
Following must be considered before starting calibration:
 Drain and perhaps clean the measuring chamber
 For the calibration, oil-free process water and oil is needed.
The calibration solutions are prepared in a vessel with a volume of approx.10 liters.
 The solution is homogenized with a circulating pump or a motorized stirrer before and during the calibration.
 The outlet of the vessel is connected with the sample inlet of
the Turbiwell.
 The sample flow is adjusted to approx. 20 liters per hour by a
control valve.
 The signal must be stable while the sample is flowing. For
this, double check and estimate the stability of the raw signal
which can be found in menu 2.2.1
<Diagnostic>\<Sensors>\<Turbidity>.
To start with calibration navigate to menu 3.1, <Maintenance>/
<Process Cal. ppm>. There you can choose between
 <Detect Zero>
 <Specify Slope>:
– Detect Zero
Zero point is done with oil-free process water.
Wait till the progress bar indicates the end.
– Specify slope:
A sample with a defined oil concentration is used to specify
the slope. The entered process value is used as a set point
of the calibration sample.

Calibration
The AMI Turbiwell is delivered factory calibrated. The calibration is
determined with a Formazine solution and the curve is stored in the
transmitter. Also, the emission intensity of the LED is monitored by
an external photodiode. A loss of intensity due to aging will be automatically compensated. Therefore it is not necessary to recalibrate
the AMI Turbiwell.
Some state regulations require a periodic re-calibration of a turbidity measuring instrument therefore, if necessary, a procedure for
calibration is below (Consult your local regulating agency on this requirement).
The calibration is performed with a 20 FNU/NTU formazine- standard. To make the formazine-standard the following aids are required:
 Deionized water with a turbidity < 0.1 FNU/NTU
 Formazine-standard 4000 NTU produced according
EPA 180.1, ASTM 2130B or ISO 7027
 The following laboratory equipment

4
Put the pipette into the volumetric flask and press the fast release lever until the pipette is empty.
5
Fill the volumetric flask with 1 liter deionized dilution water.
WARNING
Health hazard
Formazine is harmful to the environment.
 At no means recirculate it into the water system.
The calibration does not change the zero point defined at factory
calibration but only the slope of the calibration line.

Matching
Each verification kit has to be matched with the latest calibration
before it can be used for a verification.
The function <Matching> can either be started in menu
<Maintenance>/<Matching> or during the calibration procedure
when the question “Match Verikit” is confirmed with yes.
Up to 10 Verikits can be matched for one AMI Turbiwell. An existing
Verikit can be overwritten but not deleted.
A matching is accepted if the deviation is within ± 25%.
NOTICE: It is very important that the drainage valve is closed
during the matching process otherwise wrong measuring values
caused by residual light will result. With Instruments equipped
with automatic drainage, the drain valve opens and closes
automatically. For instruments with a manual drainage valve,
always make sure the drainage valve is closed before
matching.
The signal outputs are frozen during matching. If the matching is
finished, the signal outputs remain frozen for the time programmed
in <hold after cal.>. During this time the display shows HOLD.

Program List and Explanations
As control
output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
 P-controller: The controller action is proportional to the deviation from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
 PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
 PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
 PID-controller: The combination of a P-, an I - and a D-controller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
Ziegler-Nichols method for the optimization of a PID controller:
Parameters: Setpoint, P-Band, Reset time, Derivative time, Control Timeout

5.3 Relay Contacts
5.3.1
Alarm Relay: The alarm relay is used as cumulative error indicator.
Under normal operating conditions the contact is active.
The contact is inactive if:
 Power loss
 Detection of system faults like defective sensors or electronic
parts
 High case temperature
 Lack of reagents
 Process values out of programmed ranges.
Program alarm levels, hysteresis values and delay times for the
following parameters:
Meas. value, Sample Flow
5.3.1.1
5.3.1.1.1
Alarm
Alarm High: If the measured value rises above the alarm high
value, the alarm relay is activated and E001, is displayed in the
message list.
Range: 0–250 FNU/NTU
Alarm Low: If the measured value falls below the alarm low value,
the alarm relay is activated and E002 is displayed in the message
list.
Range: 0–250 FNU/NTU
Hysteresis: Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value
fluctuates around the alarm value.
Range. 0–250 FNU/NTU
Delay: Duration, the activation of the alarm relay is retarded after
the measuring value has risen above/fallen below the programmed
alarm.
