2. Product Description
Application Sodium measurement is used for quality control in high purity water
applications and to monitor break through of mixed bed ion ex-
changers, condenser leaks and the prevention of caustic corrosion
of turbines. The AMI Sodium P is suitable for samples with a pH
value higher than pH7. For samples with a pH lower than pH7, use
the AMI Sodium A.
Measuring
principle
The sodium measurement used in this instrument is based on a po-
tentiometric measuring method. For this purpose a proven sodium
ion sensitive glass electrode and a reference electrode is used.
These two electrodes produce a different electrical potential which
is used to calculate the sodium concentration of the sample. Ac-
cording to Nernsts Law, the ion concentration depends on the tem-
perature, therefore a temperature sensor measures the sample
temperature. With the current temperature the measuring value is
expressed for the standard temperature of 25 °C by using pro-
grammed temperature compensation curves.
Sodium measurements below 1 ppb require a special glass formu-
lation for the sensing electrode response.
Ammonium and pH interferences from the unconditioned sample
are eliminated by a suitable reagent. The measuring limit of 0.1 ppb
sodium requires the conditioning of the sample to a minimum of
pH 10.5 while sample integrity has to be maintained. The best re-
sults are obtained with Diisopropylamine (DIPA).
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.
Maximum load: 1 A / 250 VAC

RS485 Interface with Fieldbus protocol Modbus or Profibus DP.
Consumables The filling of the 100 ml KCl Bottle lasts for one month of operation.
On-line
Operation
The sample flows via the sample inlet [D] and the flow regulating
valve [C] into the constant head [A]. Adjust the flow regulating valve
so that always a small part of the sample flows through the overflow
tube [M] into the waste. This adjustment ensures a sufficient sam-
ple flow through the flow cell [K]. First the sample flows into the
measuring chamber [K1] where the sodium electrode [G] is installed
and the sodium concentration of the sample is measured. From
there it flows into the measuring chamber [K2] where the pH elec-
trode [F], the temperature sensor [H] and the reference electrode
[E] are installed and thereafter it flows via flow cell [K3] through the
sample outlet [L].
During on-line operation, the standard bottle holder [Q] is complete-
ly turned down, and the sample flows from the constant head [A]
into the reaction tube [B].
Due to the different level of the constant head and the flow cell, a
negative pressure is created in the reaction tube [B]. As a result, re-
agent saturated air is sucked into the reaction tube, raising the pH
of the sample to a value of 10.5, and forming a regular stream of air
bubbles [J].
The bubble stream is used to monitor the correct sample flow with
the bubble detector [I]. An inconsistent sample flow causes an in-
terruption of the bubble formation and produces a system error.

Second
Sample Stream
If required the AMI Sodium P can be equipped with the optional
second sample stream module. To install the 2nd sample stream
option a AMI Sodium P with 400 mm panel with is required.
Sample
Sequencer
If measurement of more than two sample streams is required, the
AMI Sodium P can be connected to a Sample Sequencer which al-
lows to measure up to six sample streams.
Grab Sample The standard bottle holder can also be used for a grab sample
measurement. Grab sample measurement see Grab Sample, p.
51.
Calibration A standard bottle is screwed in the standard bottle holder [Q] and
turned upwards into the vertical position, thus switching the sample
flow from the constant head to the standard bottle. Constant pres-
sure within the standard bottle is maintained by the pressure-equal-
izing tube inside the bottle.
1 liter standard is consumed in approx. 10 min. The sodium elec-
trode must reach constant readings within this time to obtain an ex-
act calibration.
For details, see Calibration, p. 42.

AMI Sodium P
Installation
A-96.250.211 / 200416 17
3. Installation
3.1. Installation Check List
Check Instrument’s specification must conform to the National Electrical
Code, all state and local codes, and all plant codes and standards
for electrical equipment.
On site require-
ments
100 - 240 VAC (10%), 50/60 Hz (5%) or 24 VDC, isolated
(±10%) power outlet with ground connection and 30 VA
Sample line with min. 100 ml/min and 0.3–3.0 bar (4–43 psi)
Waste line with pressure free drain.
See Connecting Sample and Waste, p. 21.
Installation Install the instrument in vertical position.
Display should be at eye-level.
Connect the sample and waste line(s).
See Connecting Sample and Waste, p. 21
Electrodes Sodium electrode: Install the Sodium Electrode, p. 21.
Etch the sodium electrode
Rinse it well and check for air bubbles inside the electrode.
Install the sodium electrode.
Connect cable S to the sodium electrode.
Reference electrode: Install the Reference Electrode, p. 23.
Install KCl bottle,
Check the ground joint diaphragm
Install the reference electrode.
Puncture the KCl bottle.
Connect cable R to the reference electrode.
pH electrode: Install the pH Electrode, p. 27.
Install the pH electrode.
Connect cable pH to the pH electrode
Reagent and
filter connec-
tions
We recommend to use DIPA to operate the instrument. Use a
reagent bottle with either G45 thread (Schott) or a bottle from
Merck using a thread adapter. Close the bottle well to prevent the
formation of reagent vapors. For installation see Install Reagent
Bottle, p. 44.
Install the air filter.

AMI Sodium P
Installation
3.2. Mounting of Instrument Panel
The first part of this chapter describes the preparing and placing of
the instrument 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
material is available:
– 4 Screws 8x60 mm
– 4 Dowels
– 4 Washers 8.4/24 mm
Mounting re-
quirements
The instrument is only intended for indoor installation.
For dimensions see Dimensions:, p. 14 or Dimensions with 2nd
sample stream, p. 15.
Electrical Wiring NOTICE: Do not switch on the Instrument until all electrical
connections are made.
Connect all external devices like limit switches, see Electrical Con-
nections, p. 22.
Connect power cord.
Power-up Turn on the sample flow and wait until the measuring cell is com-
pletely filled.
Adjust the sample flow until the bubble stream is regular.
Switch on power. See Establish Sample Flow, p. 39
Instrument
Setup
Program all parameters for external devices (interface, recorders,
etch.). Program all parameters for instrument operation (limits,
alarms, measuring interval).
Run-in period Let the instrument run continuously for 1 h.
Calibrate pH See pH Process Calibration, p. 43
Calibration
Sodium elec-
trode
Rinse the standard bottles well with deionized water. Prepare the
sodium standards directly in the graduated standard bottles using
a precision pipette. Make sure the concentrations are programmed
correctly. Perform a two point calibration.
See Calibration, p. 64
