Flow Thru Liquid Sampler

The flow thru sampling system consists of a full flow process diameter sample valve that allows for continuous flow through a pipe line.

Against the competition the Mechatest flow thru sampler body and valve is made from forging 316/316L bar material or higher grade Alloy with the advantage that both mechanical properties and corrosion resistance are much higher to those of the “equivalent” wrought grades.

The rising stem sample valve allows the operator to control the flow of the sample being dispensed into the sample bottle. This system can be used for medium pressures, temperatures and high viscous fluids where a continuous flow loop is needed. Easy to install and operate, the sample flows into the sample bottle by opening a needle valve.

This flow thru sample valve is mostly combined with our ECO Needle Sampler with glass bottle, the process pressure pushes the sample through the valve into the bottle via a sample needle. Optional with Process Needle Purge connection, zero dead volume is ensured.

Flow Thru Liquid Sampler for Loading Arm Sampling

Mechatest offers a broad line of flow thru liquid sampling solutions, all available in a wide range of materials and fully compatible with the requirements of the Oil & Gas, Petro-Chemical and Chemical industries. 

The flow thru sampler can be used in a lot of applications but mostly direct mounted into piping systems, this type of sampler is the better solution for loading arm sampling.

  • Flow Thru Sampling Valve in sizes 1/2", 1", 1.5" and 2" NPT connection or flanged
  • Choice of materials from AISI 316(L) to special alloy solutions for highly toxic areas
  • All flow thru samplers comply with NACE MR-01-75 / MR-01-03 standards.
  • Rising stem needle valve with Ceramic stem ball tip Al2O3, Superior hardness prevents deformation of the sealing tip and wear, significantly increasing the lifetime of the product for isolation purposes.
  • Connections, pressure and temperature ratings varieties
  • Bonnet assemblies offer different stem, seal and material selections
  • Wide variety of sealing materials; PTFE; Grafoil®; Fluorocarbon FKM; NBR; EPDM; Silicon; and perfluorelastomer providing a wide coverage of applications.
  • Extensive range of valve configurations and flow schemes
  • Fully equipped instrument enclosures
  • Creating closed loop systems which provide a safe sampling and controlled environment, emission free
  • Option for Fixed volume sampling, which minimizes both waste and costs
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Venting needle for proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent systems, and professional services by our team of specialists. We are always inspired by the need to evolve and stay ahead of the ever-changing marketplace.
