Feature

  • There are no blocking and rotating parts in the measuring chamber creating no resistance
  • It can measure flow rate as low as 0.003 m3/s. It can be used for monitoring gas drainage in both single holes and confluent pipelines at drilling sites
  • It can output and display two modes of working condition and standard condition, which is convenient for data collection and query
  • The instrument has the function of wireless data transmission. Data can be transmitted wirelessly between testers and between the tester and the underground wireless base station (optional)
  • Explosion-proof type: mining intrinsically safe (Ex-mark: Exia I Ma)
  • Protection grade: IP65
