Device for measuring flow rate in a pipe, and distillation installation of the Charente still type comprising the same

摘要

The flow rate measurement device (7) includes two pressure take-offs (9, 10) respectively upstream and downstream of a diaphragm (8) capable of varying the cross-section which it blocks in the pipe, in order to allow a working position in which it measures the flow rate and a rest position in which the cross-section which it blocks is minimised. The distillation installation includes means for adjusting the rate of removal of burnt gases to a predetermined value as a function of the setting of the fuel supply of the combustion chamber, these means including such a device (7) for measuring the flow rate of the burnt gases in the flue, as well as a turbine machine (12) for forcing the extraction of the gases.
