The CoJetix system is the highest accuracy sampling system for custody transfer applications in 8" to 52" pipelines. It is a combined fast loop and JetMix system that has a sampling system mounted in a 1" or 2" bypass loop mounted as part of the JetMix loop. The main loop take-off is a 'quill' inserted directly into the pipeline through a valve and seal housing allowing removal under line conditions. Flow is returned to the main pipeline, upstream of the quill by a JetMix mixing nozzle.
The sampling loop is designed so that loop velocity is sufficiently high to maintain homogeneity at all times and mounted in the receiver housing in the loop are a full-bore cell sampler, flow indicator and isolation valves. The cell sampler isolates and discharges a 'grab' sample directly through the bottom of the sampler into a sample receiver.
The main components of the sampling system are mounted inside a receiver housing allowing them to be easily isolated and serviced without needing to shut down the main pipeline. The receiver housing can be heated if required and may contain multiple receivers with manual or automatic changeover. If compliance to ISO 3171, ASTM D 4177, is required the system is fitted with a CanWeigh receiver weighing system that continually measures the sampling system
performance, as specified by the sampling standard. Sample receivers can be removed to the laboratory where they can be re-mixed with a suitable mixing system prior to sample analysis. The system is controlled by a sampler controller using a suitable flow signal to pace the sampler.
All Jiskoot systems are designed in accordance with all the international sampling standards and supplied with a guarantee of compliance and a warranty.
