METHOD FOR TESTING GAS METERS OF HIGH RATE OF FLOW AND TESTING STATION DEVICE FOR CARRYING OUT THIS METHOD

摘要

A multiply and forced air circulation is provided in a closed testing circuit, while its velocity is related to the required rate of flow. Its temperature and humidity is kept related to the air values existing in the surrounding of the testing station and this external air enables to exchange circulating air, while this exchange efficiency may be controlled. The equipment used for verification of polymers, equipped with air condition unit (2), connecting element (4) or with the dilatation sleeve (3) actually, is connected to the closed testing circuit. This circuit has a connection to an external environment via connecting element (4) and this element may be created as the ejector with the jet (6), as for instance, suction hole (7) and at least one outlet channel (5), the efficiency value of which can be set. The inlet testing pipe (9) or outlet testing pipe (11) enables to be moved in the direction of its axis, via dilatation sleeve (3).
