The Maurer® insertion sampler is designed for directly connecting to a 2" NB pipe nozzle flange or to fit through 2” full bore flanged isolation valve on the main pipeline to be sampled. The sampler stem has a flow through port where sampling mechanism will periodically grab a 1cc sample.
The sampler is essentially a power driven metering pump. The patented 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.
