2. Product Description
Application The AMI Turbitrace is used for the measurement of low level turbidity
in pure and ultra pure water.
Measuring
Principle
Turbidity is a measure of how much of the light traveling through wa-
ter is scattered by suspended particles. The scattering of light in-
creases with increasing suspended solid. The intensity of light
scattered at 90° as a beam of light passes through a water sample is
measured and indicates turbidity of the sample.
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear or bilinear) or as continuous control output (control pa-
rameters 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).
Relay Two potential-free contacts programmable as limit switches for mea-
suring 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
Alarm Relay One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and in-
strument faults.
Input For potential-free contact to freeze the measuring value or to inter-
rupt control in automated installations (hold function or remote-off).
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory. Over voltage protection of in- and outputs.Galvanic separa-
tion of measuring inputs and signal outputs.
Communica-
tion Interface
(optional)
USB Interface for logger download.
Third signal output (can be used in parallel to the USB interface)
RS485 with Fieldbus protocol Modbus or Profibus DP
HART interface

Measuring
Principle
The light beam emitted by the emitter LED [L] passes through the
sample and is received by the transmitted light beam sensor [J].
Some light will be scattered by particles contained in the sample and
received by the scattered light sensor [K], which is placed in a 90°
angle to the emitter LED. The ratio between the signal strength of the
signal receiver and the reference receiver is a measure for the tur-
bidity of the sample.

On-line
Operation
The sample flows through the sample inlet [F] via solenoid valve [G]
and the manual 5 way valve [E] into the measuring chamber [B],
where the turbidity is measured. From there it flows through the sam-
ple outlet [C] and the pressure regulator [K]. The pressure regulator
is used to regulate the sample flow. Then the sample flows via capil-
lary [L] and flow meter [M] into the drain funnel [N].
To keep the measuring chamber clean and free from deposits it can
be cleaned by opening the drain valve [D].

2.1. Instrument Specification
CAUTION
The measuring chamber is under the pressure of the
sample line
If the inlet pressure is too high, moisture can enter the housing of
the measuring electronics and lead to incorrect measurements
and failure of the instrument.
The maximum inlet pressure of 10 bar must never be
exceeded, not even for short time periods. Take appropriate
measures to protect the instrument from pressure surges in the
sample line.

3.3.3 Adjust the Sample Flow with a Capillary Tube
The AMI Turbitrace is as standard delivered with the capillary FEP
tube with an inner diameter of 1 mm and a length of 500 mm.
If you have a low sample pressure or you need a high sample flow, a
shorter capillary with 186 mm length can be used.
To replace the capillary proceed as follows:
1Pull out the knob of the pressure regulator valve [A].
2Close the valve.
3Push in the knob to lock the valve in closed position.
4Unscrew and remove the tube fittings [B] of the capillary [C].

The capillary tube determines the flow resistance and the maximal
flow rate. With the pressure regulator at the inlet side of the capillary
the flow rate can be adjusted within the given range, see diagram be-
low.
The standard capillary is an FEP tube with an inner diameter of
1 mm and length of 500 mm. If you have a low sample pressure or
you need a high sample flow, a shorter capillary with 186 mm length
can be used.
