1.3. Restrictions for use
Alcalizing
Reagent
Correct the pH of the sample with Diisopropylamine only, however,
Diisopropylamine is not included in delivery. Please buy it from your
local supplier: E.g. VWR 6x 1l: 8.03646.1000, or SIGMA 38290-1L-F.
Sample
Require-
ments
No sand (or other polishing material) or oil are allowed in the sam-
ple.
The instrument is specified for a max. pressure of 2 bar (28 psi). If
the sample pressure exceeds 2 bar, please mount a pressure re-
duction in front of the instrument inlet.
Phosphates may interfere with the hydrazine measurement.
The pH value of the sample must be equal or higher than pH 7.
Flow
Interruption
High concentrations of Diisopropylamine reagent may attack the
acrylic material of the flow cell. This can cause cracks and render
the flow cell completely unusable. This will not happen during nor-
mal operation. However, if the sample flow is stopped, undiluted di-
isoproylamine will diffuse through the diffusion tube and can cause
damage. Therefore, the following rules should be observed if the
sample flow is stopped for more than one day:
Remove diisopropylamine bottle and close it. Keep it in a safe
place for further use.
WARNING
Diisopropylamine is corrosive.
Read the Safety Data Sheets (SDS) first.
Wear suitable protective clothing, gloves and eye/face protec-
tion.
Avoid inhalation of DIPA vapor.
In case of contact with eyes, rinse immediately with plenty of
water eyelid wide open for at least 10 min, summon medical
advice. In case of accident or if you feel unwell, summon
medical advice immediately (show the label where possible).
Screw an empty reagent bottle on the holder.
Let the sample flow for another 30 minutes to rinse out the Di-
isopropylamine dissolved in the diffusion tubing material.
Stop sample flow.

Product Description
2. Product Description
2.1. Description of the System
Microprocessor controlled system for the determination and control
of hydrazine or carbohydrazide used as boiler feedwater oxygen
scavengers.
Application Hydrazine is used in power plants as an oxygen scavenger. It helps
to remove oxygen, which may cause corrosion in the power plant.
The reaction of hydrazine with oxygen produces nitrogen and wa-
ter.
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear, bilinear, log) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 
Third signal output with the same specifications as option.
(Only possible if no communication interface is used.)
Relays 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
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 One input for potential-free contact to freeze the measuring value
or to interrupt control in automated installations. Programmable as
HOLD or OFF function.
Communica-
tion interface
(optional)
HyperTerminal Interface (RS232) for logger download.
USB Interface for logger download.
Profibus/Modbus interface (RS485) with Fieldbus protocol.

Features

memory.

analyzer is factory tested and ready for installation and operation.
Reagent
consumption
Reagent consumption (at 25°C):
< 1L diisopropylamine per month
Measuring
principle
3-electrode amperometry:
The sensor consists of two platinum electrodes and a reference
electrode. A voltage is applied to the platinum electrodes and kept
on a optimum level by the reference electrode. The hydrazine in the
sample generates a small current on the platine pin electrode,
which is proportional to the hydrazine concentration.
For an optimal sensitivity and stability, a rotor continuously cleans
the surfaces of the platinum electrodes (hydrodynamic cleaning).
To ensure a sufficient sample flow, a Hall-Sensor detects the rota-
tions of the rotor. If the rotation speed falls below a certain value, a
flow Alarm is triggered.
The signal of amperometric systems depends on flow rate. The
constant head guarantees a constant flow if the sample always
overflows into the longer constant head tube.
Temperature compensation is done automatically.
Fluidics The measurement of hydrazine requires a high pH of the sample.
The AMI Hydrazine buffers the pH to pH>10.5 by adding diisopro-
pylamine. The diisopropylamine is dissolved in the water while
flowing through a diffusion tube.
The sample enters at the sample inlet [E], passes the filter [G] and
the flow regulating valve [D], where the sample flow can be adjust-
ed. From there it flows through the diffusion tube [L] in the diisopro-
pylamine bottle [K], picking up diisopropylamine and reaching
pH>10.5. Afterwards, the sample is led directly into the shorter
overflow tube [C]. From there it flows through the hydrazine sensor
[F] and leaves the flow cell via sample outlet [H]. Excess sample
overflows from the shorter overflow tube into the constant head [A],
fills it until the sample overflows into the longer overflow tube. Sam-
ple must always overflow into the longer overflow tube to ensure
constant flow and pressure at the hydrazine sensor. The sample
leaves the flow cell via sample outlet [H].
