MOBILE prover calibration unit for the control-verification testing of liquid FLOWMETERS

摘要

The utility model refers to a model fluid flow measuring means, designed for verification of fluid flow measurements on oil and gas production, oil and gas and oil transport or other companies and is aimed at simplifying the design of pipe calibration unit (TPU), reduction of manufacturing costs and maintenance for periodic connection to the process for verification of installed therein fluid flow measurements directly in the production line in real conditions of their operation. Said technical result is achieved in that the piping system, comprising inlet pipe 2, outlet pipe 3 measuring duct section 4 with a ball plunger with a calibrated portion of the pipeline, the inlet tee 16 outlet tee 20 and three-way ball valve 23, mounted on the frame 1 mounted on towed by a trailer 10 (or the vehicle) and provided with two flexible high pressure hoses, power cable 7 and a block of measuring and computing system 9, wherein in the axial through passage ball plug three-way ball valve 23 installed plug to be disposed in the ball of the ball plunger stopper. 2 h.
