BLZZRD Portable Refrigerated Sampler
Section 7 SDI-12 Sondes
7-2
7.2 SDI-12 Data
Parameters
The BLZZRD Sampler can accept up to 16 parameters from up to
ten sensors with SDI-12 addresses from 0 - 9 (refer to Table 7-1).
This data can be used in different ways. Data can be logged at
user selectable time intervals for later download and processing
by Teledyne ISCO’s Flowlink® program. You can set up sampling
programs that will be enabled to run only if conditions based on
parameters monitored by the connected SDI-12 devices are met.
The sampler can also be programmed to take samples each time
certain parameter limits are exceeded.
The data parameters used by the sonde and sampler must
match. Otherwise, the equipment could record the data values
for one parameter as another’s, such as reporting a pH value as
being temperature.
Some sondes, such as the AQ700, have “plug and play” setup.
Known as “ISCO Ready,” these sondes can tell the sampler what
values they have, their order, and units of measure. Other
SDI-12 compatible sondes can still be used, but require manual
setup to identify proper data types for each data value reported.
This section shows you how to set up both ISCO Ready and other
SDI-12 sondes for use with the sampler.
WARNING
SDI-12 Sondes have not been approved for use in
hazardous locations as defined by the National Electrical
Code.
CAUTION
Before you install any sonde, you must take the proper safety
precautions. Refer to Appendix C in the back of this manual.
Additional safety considerations may be required. Check appli-
cable guidelines, codes, and regulations of federal, state, city,
and county agencies.
