GDS Gas Dilution System
The sampler and dilution unit are in a single cabin. Flow control of
both units is done with two independent mass flow meters integrated into the device. Total and dilution gas volume can measure with two independent dry gas meter. All of this process is automatic and controlled by the device's microprocessor.
The two streams are regulated independently, so for different stack
condition the dilution ratio can be changed indepandantly. The
temperatures inside both dry gas meters reads with two tempreture
sensor and stores in the memory of the sampler.
The dilution and total sample inlets are equipped with two easily replaceable cartridges. In addition, the user can easily replace the cartridge silica gel and charcoal. Unlike traditional manual sampler, it is fully automated. Dilution and total flow rates can be adjusted digitally. The sampler automatically controls the set flow rates and adjusts the flow rates. The sampler also directly reads gas volumes and temperatures from the dry gas meter. Thus, it is not necessary to note the first and last readings and temperatures from the dry gas meter.
