FIELD: physics, measurements.
SUBSTANCE: invention is designed for metrological tests of flow metres by weight and volume methods. Device comprises accumulator tank (1) for liquid arranged as bearing in the form of parallelepiped, equipped with flooring (14) and mutually connected by means of pipeline branches (2, 12) with controlled pumps (4, 13) installed in them with receiver 5 for smoothening of liquid pulsations and removal of air bubbles from it. On flooring pipeline section (6) is arranged for installation of calibrated flow metres (19), flow distributor arranged in the form of pipeline (7) branched at least into two branches with section (8) for installation of control flow metres (20), dynamic flow distributor (9) and weight tanks (11) installed on scales (10), which differ by volume, and also control panel (16).
EFFECT: provision of possibility to calibrate flow meters in single hydraulic circuit in wide range with high accuracy due to stabilisation of liquid level oscillations in accumulator tank and reduction of static pressure oscillations in suction section of pumps.
