FIELD: oil field equipment. SUBSTANCE: device may be used for integral sampling of multicomponent gas-liquid systems transported by pipelines. The sampling device has body, sampling chamber with intake holes, shutoff member with control handle and guide tube. Sampling chamber is installed in body on rotation supports and in off-position it is located beyond the space designed for motion of process flow. In operating position, device is found in the space. Intake holes uniformity cover one part of section of process flow. Shutoff member is located in rotation support and made in the form of check valve engageable with movable rod of removable control handle connected with guide tube. Sampling device allows taking sample simultaneously over entire section of process flow with equal intensity to ensure maximum degree of identification of sample and to prevent hazard of freezing the device in winter. EFFECT: higher efficiency. 6 cl, 9 dwg
