Jiskoot loop extractors

Ensure representative liquid sample extraction for accurate process measurement and analysis

Applications

Sampling and analysis fast-loop operations

Benefits

Acquisition of representative sample
Streamlined entry profile that prevents preferential bias caused by specific gravity variation in mixed fluids
Optional integrated return that eliminates the need for separate entry and exit points on the line

Features

Large-bore sample bypass
Fixed or withdrawable mounting designs
Hydraulic extractor available

How they improve performance

Jiskoot™ loop extractors are engineered to provide representative liquid sampling for cell samplers, water monitors, densitometers, and online analyzers. Designed to extract a slipstream from the well-mixed region of the pipeline, their unique knife-edged, swan-neck take-off minimizes sampling bias and ensures that the extracted sample accurately reflects process conditions.

An integrated return reduces installation complexity and hot tap requirements, while accelerated loop flow helps prevent component fallout and minimizes volume and time lag. Available in both fixed and withdrawable configurations, these loop extractors provide a robust, reliable solution for maintaining sample representativity and supporting accurate process measurement and analysis.
