Design of mine-used multi-parameter gas flow sensor

More Information
  • In order to solve problem that traditional gas drainage monitoring system needs many sensors, cables and has inconvenient installation and maintenance because of too many monitored parameters, the paper designed a new kind of mine-used multi-parameter gas flow sensor. The sensor can measure gas flow with flow rate between 0.3 m/s to 30 m/s in pipeline with diameter between 80 mm to 1 000 mm. The sensor only needs a mounting hole for installation, and uses a four-core cable to transfer signals of flow, temperature and pressure to transmission substation by RS485. Industrial test results show that the sensor has high range ratio, good stability and practicability, and can reduce workload of preliminary research, construction and maintenance of gas drainage monitoring system.
