Figure 176 Flow based sampler counter selection
Weighted sampler
Of course it is important to ensure that the sampler can is not overfilled. Here it is important to
know if the check is done on volume or mass.
In case of mass, the weight of both the possible cans is checked. Please note that this is a check
only against one or two analog inputs for the measured sampler can weight “can A and B input”
The parameters to check the cans are as follows:
Figure 177 Sampler can weighing
Sample measurement Measurement based on volume or mass
Sample can mass unit Selectable units for mass measurement – ibs or kg
Sample can weight deviation Maximum deviation allowed between sampling and the weight of can A
and B
Same can maximum weight Alarm limit for the weight of can A and B
Sample can high weight Warning limit for the weight of can A and B
Sample can reset time Change of can indication resetting all preset information (not
implemented yet)
Flow limits
It is important to get a representative sample in the can. If the flow is very low this might not be
the case. Simularly if the flow is too high, the flow to be counted in the error counters instead of
the normal counters, so the sample would not reflect the normal count. For this reason, limits
can be set outside which sampling may not occur:
