Pneumatic Cell Sampler - MCS31

The Maurer® pneumatic cell sampler is designed for connection in a fast flow loop (bypass) from the pipeline to be sampled. The sampler comprises a flow cell integrated with a sample collection mechanism. Having the sampler in a fast loop rather than directly in the pipeline has advantages for system integrity, reliability, and servicing.

The sampler is essentially a power driven metering pump. The sampling mechanism is a tubular stem with an inner concentric capture tube and a piston. Each cycle first captures a precise volume of sample and then pumps it through a back pressure valve to a sample collection receiver. The sampler can be operated at up to a maximum of 15grabs/min.

The in-line sampler installed in a properly designed system will take representative grabs of sample at a pre-determined rate normally relative to the pipeline flow rate. The composite of the 1,000 to 10,000 grabs collected during a pipeline transfer provides a representative sample of the oil batch, for lab analysis and reference.


The major use is for sampling crude oils and associated production fluids such as NGL and refined products for the measurement of water content, light ends, density and sulphurs to name a few analyses.
