Abstract
Measuring device comprising a flow meter (26) provided with an inlet and an outlet which are each intended to be connected to a conduit in which a polyphase outflow to be measured flows, originating, for example, from an oil well, and a first valve (28) arranged below the flow meter (26), the flow meter being mounted generally vertically. According to the invention, the device furthermore comprises a branch passage (34), provided with a second valve (36), opening above the flow meter, so that it can be filled selectively with liquid using this branch passage (34).
