1.3. Restrictions for use
Sample Re-
quirements
Flow rate: 20–60 l/h
Temperature: 1–45 °C.
Swan recommends that the sample temperature is no
more than 20 °C above the ambient temperature.
The outlet has to be pressure-free against atmosphere.
Sample degasser: Only to be used for turbidity below 1 FNU/
NTU.
Flow rate of sample inlet at degasser: 10–12 l/h.
Maximum turbidity of the sample:

– Turbiwell W/LED: 100 NTU
CAUTION
Wrong measured values due to dirty optical components.
Touching the optical components in the cover of the measuring
cell may result in wrong measured values.
Cleaning and re-calibration at SWAN is necessary.
Never touch the optical components.

2. Product Description
Application The AMI Turbiwell is used to measure turbidity in potable water, sur-
face water, effluents and water steam cycles.
The turbidimeter is also suitable for the measurement of other liquids
of which the turbidity correlates with the concentration of a suspend-
ed solid or an emulsified liquid, e.g. oil in water. See chapter ppm
Calculation, e.g. “Oil in water”, p. 48 for details.
Available
Models
The instrument is available in three different models:
AMI Turbiwell 7027: with an IR LED according to ISO 7027
AMI Turbiwell W/LED: with white light LED (approved, alterna-
tive method to US EPA 180.1)
AMI Turbiwell Power: variant on steel panel with IR LED
according to ISO 7027
Configurations
and Options
The AMI Turbiwell 7027 and the AMI Turbiwell W/LED are available
in the following configurations:
Automatic or manual drain valve
Sample degasser (option)
deltaT flow sensor (option)
Flowcontroller (option)
On small panel with remote transmitter
The AMI Turbiwell Power is equipped with a flow meter as standard
and available in the following configurations:
Automatic or manual drain valve
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 Ω
Third signal output available as an option. The third signal output can
be operated as a current source or as a current sink (selectable via
switch).

sured values, controllers or timer for system cleaning with automatic
hold function. Both contacts can be used as normally open or nor-
mally closed.
Maximum load: 1 A / 250 VAC

Measuring
Principle
Nephelometric system: A water sample colored by dissolved sub-
stances is a homogeneous system that only attenuates radiation
passing through the sample. A water sample containing undissolved
substances attenuates radiation and, additionally, the insoluble parti-
cles scatter the radiation unequally in all directions.
To obtain the turbidity value of the sample, the diffuse radiation is de-
termined 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. At 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
The sample enters at the sample inlet [G]. The constant head [H]
guarantees a constant sample flow into the measuring chamber [J],
and air bubbles are removed. Excess sample overflows directly into
waste 1 [I]. The sample flows into the measuring chamber, fills it, and
then flows via overflow [F] into waste 1. The LED beam impinges con-
tinuously 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 [K] is used to empty the measuring chamber for
maintenance work like cleaning the measuring chamber or perform-
ing a verification.
Verification For the verification, three different verification kits (low turbidity, high
turbidity, liquid) can be used. The kits are available as an option.
Calibration The AMI Turbiwell is factory-calibrated, therefore it is not necessary
to perform a calibration in the field. The emission intensity of the LED
is monitored by an external photodiode. A loss of intensity due to ag-
ing will be automatically compensated.
To meet the requirements of some public authorities it is possible to
calibrate the instrument with a formazine standard.

2.1. Instrument Specification
Note:
• If the maximum sample temperature of 45 °C is exceeded for a
short time, the instrument will not be damaged.
• Swan recommends that the sample temperature is no more
than 20 °C above ambient temperature. With increasing
temperature difference condensation will form to a higher
extent, but the measurement will not be affected. However, it is
possible that a temperature difference significantly higher than
20 °C will cause condensation directly on the optics, which can
lead to incorrect measurements.

Setup
Program all parameters for external devices (interface, etc.).
Program all parameters for instrument operation (limits, alarms).
Run-in time Let the instrument operate for 24 h without interruption at normal
sample conditions to rinse out any pollution from manufacturing and
transport.
Matching Each verikit has to be matched with the current calibration values
before it can be used for a verification.
Verification Never perform before the run-in time is over and before the mea-
sured value is stable.
Can be performed to verify the device functions.
