Size Range
Standard models range from 4" to 12" inlet diameter. Custom designs are available outside this range.

Flow Rates
Typical flows range from a few hundred pounds per hour to over 250 tons per hour. Since the sampler is installed as an integral part of the vertical pipe or chute, it is built to handle what ever flows normally in the line.

Sample Fraction
Sample fractions generally range from 0.015% to 0.04% depending on the process and customer needs. Custom models have been designed for as high as 5.0% and as low as 0.007% of process stream flow.

Temperature
Each sampler is built according to customer specifications for materials of construction. Usually the unit is built from the same material as the process piping so that temperature limits of the sampler are adequate.

Materials of Construction
Standard models are available in mild steel, aluminum and stainless steel. Other materials are used as indicated by the specific process application.

Abrasion
Special materials are used when high abrasion is a concern. Some models have refractory components to withstand both high temperature and abrasion conditions. Other models incorporate AR steel plate for high wear points.

Maintenance
Since there are no moving parts or electronic devices, this sampler is virtually maintenance free. Each first-stage sample collection chute is accessible through standard covered openings in the upper transition piece. First-stage chutes are replaceable without special tools and without removing the sampler from the process line. Second stage chutes are also replaceable.

Installation
The sampler is inserted in the vertical process line as a spool piece. Installation costs are minimal since no electric, pneumatic or hydraulic components are involved. Additional mechanical support is rarely required. In such cases, the sampler is supported by the process line.
