Pneumatic Insertion Sampler MCS70

The sampler is essentially a pneumatically driven metering pump. The sampling mechanism is a turbular 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 to a sample collection receiver. The sampler can be operated up to a maximum of 30 grabs/min.

The in-line sampler installed in a correctly designed system will take representative grabs of sample at a pre-determined rate normally relative to the pipeline flow rate. The compositevof the 1,000 to 10,000 grabs collected during a pipeline transfer provides a reprasentative sample of the oil batch, for lab analysis and reference. The rate of the sampler is normally controlled by a flow computer which measures flow in the main export pipeline.

Application

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.
