Smart Ultrasonic Gas Meter

Product overview

Ultrasonic measurement is based on the time difference of ultrasonic propagation in gas medium. Using a pair of ultrasonic sensors installed in the upstream and downstream of the flow channel, the velocity of the gas medium is calculated by using the propagation time difference of the ultrasonic signal along the downstream and upstream directions in the gas medium, and then the instantaneous flow rate and cumulative flow rate are calculated.

Functional features

  • Two-way non-differential measurement, the accuracy of the gas meter reverse installation and forward installation are consistent
  • No moving parts, no wear, no noise, stable operation, long life
  • Photoelectric data port: wildly equipped with communication networks such as LCFDA, NB-IoT, LoRa
  • Protection level:IP67
  • Power supply 1: 3 × 1.5 V alkaline AA batteries, user-replaceable, life is not less than 3 years
  • Power source 2: Built-in lithium battery, the service life is not less than 10 years
  • Shut valve alarm for small flow leakage, large flow abnormal use and constant flow abnormal overtime
  • Disassemble close valve alarm
  • Built-in electric valve, can realize alarm closing valve, remote closing valve, low battery voltage closing valve
  • Measure the gas temperature and close the valve under abnormal conditions
  • Wide range ratio: household meter 1:375; industrial and commercial meter 1:1000
  • Measuring accuracy is not affected by gas composition and temperature
  • High measurement accuracy. Error: below demarcation flow ≤ 1.5%; above the boundary flow ≤ 1%
  • Small size, light weight, compact and beautiful
