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 molyb-
date to the yellow colored silico molybdic acid respectively phospho
molybdic acid. The phospho molybdic acid is destroyed with oxalic
acid before the silico molybdic acid is reduced with ammonium
iron(II) sulfate to the heteropoly-blue complex.
The required reagents are added in 3 steps to the sample in the pho-
tometer, where they allow a precise measurement of the silica content
in the sample after the chemical reactions has been finished.
Grab sample The measuring mode grab sample allows the measurement of sam-
ples from remote locations.
Second
sample stream
If required the AMI Silica can be equipped with the optional second
sample stream module.
Sample
sequencer
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 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).
Relays 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

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 sam-
ple 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 gen-
erate 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 defined quantity
reagent of the container [J] is pumped into the measuring chamber
by the peristaltic pump [O]. Immediately after that the 6-way valve is
rotated in position 2 and the reagent 2 from container [K] is pumped
into the photometer and mixed with the reagent 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.
Position 6 of the 6-way valve is not used.

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 photometer 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 reagents
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 reagent
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 reagent
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.

 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.
The diagram below shows the process of a measuring cycle in the
time axis.

3.2. Mounting of Instrument Panel
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation ma-
terial is available:
– 4 Screws 8x70 mm
– 4 Dowels
– 4 Washers 8.4/24 mm
Mounting re-
quirements
The instrument is only intended for indoor installation.
For dimensions see 17.
