INSTALLATION FOR TESTING, INSPECTION AND SETTING OF MEASUREMENT MEASURES OF FLOW CONSUMPTION Russian patent published in 2017 - IPC G01F25/00 

FIELD: measuring equipment.

SUBSTANCE: device for testing, checking and adjusting the measuring instruments for fluid flow contains a working fluid tank, a pump, a receiver, reference instruments, a test table, feed and return hydraulic lines and an information and measuring system and a control system based on a personal computer. The unit is equipped with additional test tables, the number of which is determined by the number of simultaneously tested, verified or tunable instruments of different diameters, and, accordingly, additional supplying hydraulic lines with receivers and pumps. Also, the installation is provided with a liquid flow distributor, made in the form of pipes, which are connected to each other by locking devices and form a closed hydraulic channel. To the channel, through the pipe connectors embedded in each pipe, and locking devices, test tables with test instruments and measuring lines with standard means for measuring the flow rate of liquid and their return hydraulic lines are connected. Each testing table is hydraulically connected to the required measuring lines, namely the test table with smaller diameter with test instruments is installed next to the measuring lines with reference means for measuring a smaller range of liquid flow rate, and the test table with large diameter test instruments is installed next to the measuring lines with reference measuring means greater range of fluid flow. The proposed installation allows the use of all available test tables at the same time for testing, checking or adjusting the flow measurement instruments.

EFFECT: increase the productivity of the installation.
