Model IS-1 Sampler

Model IS-1 is our instantaneous sampler for intermediate process control. Its sample collection design is identical to our other models which have no moving parts. A continuous cut is extracted from the process stream. When a sample is required, a diverter valve is momentarily activated to deliver the collected sample.

Operation

The GRSEI Sampler is placed in the process line as a section of pipe so that all the process stream flows through the sampler. The solids stream enters through the top of the sampler then flows over the distribution cone which changes the stream into an annular or ring-shaped flow. The sample collection chutes (shown in blue) takes a portion of the annular flow. The diverter valve at the funnel outlet delivers the sample on demand, resulting in a small, instantaneous sample collected proportional to the flow.

Features and Benefits

Proportional to Flow means that the sampling fraction is fixed so that, if the flow rate changes, no bias is created.

Pressure Balanced sampling means that the sample collection and delivery are carried out under the same pressure as the process line which eliminates errors caused by reverse air flow created by rapid solids displacement of air in the sample receiver.

Iso-Kinetic sampling means that the velocity of the sampled solids is identical to the velocity of the solids in the process stream. This eliminates bias, regarding fines, that can be created by differential air flow velocities.

No Moving Parts at the point of sample collection because the sample collection design is identical to our other models which have no moving parts. A continuous cut is extracted from the process stream then, between sample delivery events, the collected sample is returned to the process stream. When a sample is required, a diverter valve is momentarily activated to deliver the collected sample.
