Calibration unit for the control-verification testing of liquid FLOWMETERS

摘要

The present utility model comprising of pipe unit (TPU) - compact prover designed for verification of fluid flow measurements on oil and gas production, oil and gas and oil transport or other companies under actual conditions of operation, if possible periodic checking TPU makes connection setup to the process for verification means installed therein fluid flow measurement or flow rate measurement means directly in TPU tehnologichesk th line, ensures high stability of measurements, enables verification of the results of flowmeters, including those based on direct dynamic measurement of the masses, which improves the accuracy of the calibration, you can use it in a variety of climatic conditions, delivered to various process plants, which reduces the time and material resources on the verification of measuring instruments. This result is achieved in that the calibration unit devices and tools are placed in a thermostated container in which is maintained a predetermined temperature, controlled humidity and pollution, for verification compact prover inlet and outlet conduits TPU disconnected rotary spectacle dampers at the inlet pipe compact prover set converter working fluid density, and for delivery and connecting in various technological installations thermostated container mount en, truck or a trailer, provided with a high-pressure flexible hoses and cables for the installation of power supply and transmitting electrical signals to a device for collecting and processing information. 6 ZP f ly-7-yl.
