Sampling system, also known as sampler, is a kind of equipment used for representative sample collection from
industrial processes. Due to the growing complexity of the industrial processes, the requirements for product analysis
increase continuously, and the safety for sampling process is given more and more consideration. The simple and
primitive sampling system has evolved into a safe and reliable closed-loop sampling system. Wanan offers two kinds of
sampling systems, namely bottle configuration sampling systems and cylinder configuration sampling systems according
to the difference of container. For bottle configuration sampling systems, the sample is drawn into the sample bottle at
atmospheric pressure. For cylinder configuration sampling systems, however, the sample is drawn into the sample
cylinder at process pressure.

Cylinder Configuration Sampling Systems

◎ Configuration: The container consists of a cylinder at both ends equipped with a needle valve and a quick-connect. The
sampler consists of tubing, valves and fittings.
◎ Operating principle: During sampling, the sample can flow into the sample cylinder via the sampling loop. When sampling
liquefied gases, a fixed amount of sample is transferred to the expansion chamber to make sure that the cylinder is not fully filled.
Close the needle valves at both ends of the cylinder to depressurize the quick-connect through the vent. Remove the cylinder from
the sampling system to complete the sampling process.
◎ Applicable process conditions: High-temperature, high-pressure, corrosive, high-toxicity, high-volatility or environmentally
hazardous liquefied gases, liquids and gases.
◎Mounting types: Wall-mounted and bracket-mounted.
