Sampler can
Also in case of volume measurement it is important to ensure that the sampler can is not over-
filled. For this reason there is an analog input for the measured can level “can input” in volume
% of full
This is compared to a can level calculated by the sampler, using the following parameters:
Figure 179 Sampler can calculated can level parameters
Sample can size Can size in ml
Sample can maximum level Alarm limit can level, in percentage of the ml
Sample can high level Warning limit level, in percentage of the ml
Sample pulse duration The time, in seconds, the output will be set to take one sample
Sample size The quantity of product, in ml, of the sample being captured
Deviation alarms
It is important to verify the proper operation of the sampler. There could for instance be a faulty
valve which would not open or which is leaking. For this reason, there is the option to check for
deviation between the measured and calculated can level:
