base.
The flow assembly is used for taking samples from pressurised systems, e.g.:
•Tanks at a height
•Pressure piping
•Conveyance using external pumps
Connections
Fig. 5: Flow assembly
a Flow assembly inflow: ¾"
b Flow assembly outflow: 1 ¼"
c Flow rate: 1000 l/h to 1500 l/h
"Caution!
The outlet of the flow assembly must be unpressurised (e.g. drain, open channel).
Application example: sampling from pressure piping
Fig. 6: Sampling from pressure piping
Use the ball valve V1 to set the flow rate to 1000 l/h...1500 l/h. When the sampling cycle
begins, you can use one of the relay outputs to control and open valve V2. The medium
flows through the pipe and the flow assembly into the outflow. When a settable delay
time has elapsed, the sampler then takes the sample directly from the flow assembly.
Valve V2 is closed again once the sample has been taken.

5.6.3 Dosing volume calibration for flow-proportional sample
using the “twiddle principle”(optional)
You must always calibrate the sample volume for flow-proportional sampling if:
–The device is being commissioned for the first time or in a new location
–The sample conditions have changed (e.g. length of the sampling hose)
–The dosing glass has been replaced.
Calibrate the sample volume as follows:
Fig. 22: Sample volume calibration for
flow-proportional sampling
1. Place an empty measuring flask (volume: approx.
500 ml) beneath the outflow hose of the dosing glass.
2. Under SET -> SERVICE - CALIBRATION -> DOSING
VOL, select the item “3 SAMPLES”.
The sampler deposits three samples in quick
succession into the prepared measuring flask.
3. In the item <DOSING VOL.>, select “Save”and in the
item <VOLUME>, enter the volume in the measuring
flask in ml.
