Process Hydrazine

The sample must always overflow into the longer overflow tube of 

the constant head. Only perform process calibration if the differ-

ence is significant.

Grab sample

Take a grab sample directly from the flow cell. Open the grab sam-

ple valve and drain water for a minute before taking the sample. 

Observe the displayed value of the AMI Hydrazine while taking the 

grab sample. The measuring value has to be stable. 

Determine the hydrazine concentration of the sample by manual 

analysis.

Compare the result with the measuring value of the AMI Hydrazine.
If the measuring value of the AMI Hydrazine has changed while 

performing the manual analysis, enter the difference between the 

measuring values of the AMI Hydrazine.

Example

Displayed measuring value of AMI Hydrazine during grab sample: 

10 ppb
Displayed measuring value of AMI Hydrazine after concentration 

determination: 15 ppb.
Determined hydrazine concentration: 8 ppb
There is a change of the measurement value of 50% during the 

concentration determination. This means, you have to correct the 

determined hydrazine concentration also with a factor of 50%.
This will result in a value of 8 ppb + (50% of 8 ppb) = 12 ppb
Finally, you have to enter 12 ppb as a process value at the AMI 

transmitter
