2. Product Description
Application
Range
The AMI Silica is a complete monitoring system for the automatic,
continuous measurement of the silica content in water of power
plants or demineralizer plants.
Silica
Measurement
The determination of silica is done by the photometric analysis of
molybdate blue at 810 nm.
Silica and ortho-phosphates react at low pH with ammonium mo-
lybdate to the yellow colored silico molybdic acid respectively phos-
pho molybdic acid. The phospho molybdic acid is destroyed with
oxalic acid before the silico molybdic acid is reduced with ammoni-
um iron(II) sulfate to the heteropoly-blue complex.
The required reagents are added in 3 steps to the sample in the
photometer, where they allow a precise measurement of the silica
content in the sample after the chemical reactions has been fin-
ished.
Grab Sample The measuring mode grab sample allows the measurement of
samples from remote locations.
Second Sam-
ple Stream
If required the AMI Silica can be equipped with the optional second
sample stream module.
Sample Se-
quencer
If measurement of more than two sample streams is required, the
AMI Silica can be connected to a Sample Sequencer which allows
to measure up to six sample streams.
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 
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 au-
tomatic hold function. Both contacts can be used as normally open
or normally closed.
Maximum load: 1 A / 250 VAC
Operating
Modes
The AMI Silica can be operated in the following 3 different modes:
Internal
External
Fieldbus
Further information see Channel Selection, 5.1.6, p. 79.
Alarm Relay One potential free contact.

USB Interface for logger download
RS485 with Fieldbus protocol Modbus or Profibus DP
HART interface
Fluidics The sample flows via the sample inlet [R] and the flow regulating
valve [Q] into the constant head [A]. Adjust the flow regulating valve
so that always a small part of the sample flows through the overflow
tube [B] into the waste [I]. This adjustment ensures a sufficient
sample flow through the measuring chamber of the photometer [F].
If no measurement takes place, the sample flows through the pho-
tometer outlet [E] where it will be aerated through air inlet [S] to
generate bubbles. Then the sample flows through the bubble
counter [H] into the waste [I].
If a measurement cycle starts, the solenoid valve [C] is activated
and the sample inlet [D] to the photometer is closed. The 6-way
valve [N] is automatically rotated to position 1 and a precisely de-
fined quantity reagent of the container [J] is pumped into the mea-
suring chamber by the peristaltic pump [O]. Immediately after that
the 6-way valve is rotated in position 2 and the reagent 2 from con-
tainer [K] is pumped into the photometer and mixed with the re-
agent 1 and the sample by the magnetic stirrer [G]. This procedure
is repeated with the 6-way valve in position 3 and reagent 3 [L] and
6-way valve in position 4 and reagent 4 [M].
After the measurement has been finished, the solenoid valve opens
and the measuring chamber is flushed.
The reagent level of the containers is monitored by the reagent lev-
el detector in container 4.
Position 6 of the 6-way valve is not used.

Product Description
Measurement
cycle
The quantities of the reagents are precisely defined by a certain
number of rotations of the peristaltic pump. After the predefined
quantity of a reagent has been sucked from the container, the
6-way valve is rotated to position 5, where sample from the pho-
tometer is sucked into the loop [P]. With the sample in the tube the
reagents are pumped into the photometer.
The measurement of the sample is carried out as follows:
The sample flows via constant head through the photometer. If a
measuring cycle starts:
1
The sample inlet is closed by activation of the solenoid valve [C].
A zero measurement is performed.
26-way valve in position 1:
the reagent 1 is sucked from the container [J].
36-way valve in position 2:
the reagent 2 is sucked from the container [K].
46-way valve in position 5:
sample is sucked into the loop, the whole quantity of the re-
agents is pushed into the photometer.
5The reagents are mixed with the magnetic stirrer, the first reac-
tion starts.
After 150 sec: 66-way valve in position 3:
the reagent 3 is sucked from the container [L].
76-way valve in position 5:
sample is sucked into the loop, the whole quantity of the re-
agent is pushed into the photometer.
8The reagents are mixed with the magnetic stirrer, the second re-
action starts.
After 90 sec: 96-way valve in position 4:
the reagent 4 is sucked from the container [M].
10 6-way valve in position 5:
sample is sucked into the loop, the whole quantity of the re-
agent is pushed into the photometer.
11 The reagents are mixed with the magnetic stirrer, the third reac-
tion starts.
After 90 sec: 12 The sample measurement is performed.
13 The sample inlet is opened by deactivation of the solenoid
valve.
 The measuring cell of the photometer is flushed.

14 6-way valve in position 5:
The reagent inlet tube is flushed with sample.
 The peristaltic pump rotates for a certain time. The reagent
free sample in the photometer is sucked into the reagent
pipe and then via loop pumped back into the photometer.
A measuring cycle takes 10 minutes.
