Flow determination in underground airways from small differential pressure measurements
A new technique for measuring the flowrate in underground airways has been developed. It takes advantage of a very sensitive differential pressure measuring transducer, equipped with a microcomputer. After a brief description of the sensor and its control unit, some of the technical characteristics investigated by tests carried out in the laboratory and in the field are discussed. Special attention is paid to the appropriate set-up of the equipment.
