FIELD: measurement equipment.
SUBSTANCE: invention may be used to assess dynamic component of gas flow supplied along pipeline in lower part of reactor during pyrolysis of worn tyres. Flow metre comprises flow converter (1) to create pressure difference, differential manometer (2) to measure this difference and connection tubes between converter and differential manometer. Flow converter (1) with one end is connected to pipeline (6) for flow of re-circulated gas, and with the other end it is connected to pneumatic reservoir of permanent volume (8) for filling with gas through flow converter from pipeline (6).
EFFECT: invention provides for measurement of re-circulated gas flow that periodically varies in time.
