Flow fitting with measuring cell

9.4 Starting up the measuring system

First

1. Check that all electrical connections are connected properly.
2. Check the water connections.

Secondly

3. Start up the sample water supply. For versions with a 

measuring module, please refer to section 

9.5 Starting up the 

measuring module

4. The minimum sample water flow is around 30 l/h.
5. Switch on the power supply, or connect the electrode cable on 

the measuring cell.

9.5 Starting up the measuring module

1. Open the isolating valve.

– Open all isolating valves between the measuring module 

input/output and the main water line.

2. Switch on the circulating pump.

– The circulating pump is switched on separately, i.e. not via 

the Oxiperm

t

 Pro control unit.

3. Deaerate the circulating pump.

– Unscrew the vent plug on the front of the motor.
– Deaerate for approximately 30 seconds.
– Screw the vent plug back in.

4. Set the flow rate through the flow fitting.

– Determine the flow rate in the flow fitting.
– Slowly close the throttle valve (turn the lever) until the 

desired flow rate is reached.

9.6 Basic settings 

Observe the Oxiperm Pro installation and operating instructions.
1. Use the [Up] and [Down] buttons on the measuring amplifier in 

the "Setup" menu to select the "Measuring cell" line, and 
press [OK] to access the corresponding menu.

2. Use the [Up] and [Down] buttons to select the desired 

AQC-D6 measuring cell, and press [OK] to return to the 
"Setup" menu.

3. Use the [Up] and [Down] buttons to select the "Measuring 

ranges" line, and press [OK] to access the corresponding 
menu.

• The following are available in the "Measuring ranges" menu:

– 0.00 - 0.50 mg/l
– 0.00 - 1.00 mg/l
– 0.00 - 2.00 mg/l
– Others: freely adjustable from 0.00 to 2.00 mg/l.

4. Use the [Up] and [Down] buttons to select the desired 

measuring range.

– You can use the "Others" selection to freely set the 

measuring range from 0.00 to 2.00 mg/l.

For further settings, please refer to the Oxiperm Pro installation 
and operating instructions.

Note

1. Switch on the sample water supply.
2. Start the measurement.

Note

The measuring cell has a running-in period of around 
one hour.
The first calibration cannot be performed until this 
time has elapsed.
Check the calibration after about a day and, if 
necessary, repeat the process!

Warning
Only authorised and qualified personnel may 
commission the measuring module!
Check the installation before starting up the 
measuring module!

Note

The pressure, temperature and water quality must 
comply with the requirements of the measuring 
module!
