Characteristic

  • Electronic display for AMR is equipped Gas Meter.
  • Enable to read accurate flow rate via mechanical index when electronic display has error.
  • A back-run stop prevents the meter from running backwards.
  • Use low-power and high-speed operating microprocessor on electronic display.
  • To replace gas meter after expiration of verification firstly need to separate DIGILOG Ass’y from gasmeter. And then reassemble both devices.
  • Output Signal for AMR (DC-PLC, RS-485, TTL, Pulse: Open Collector, etc. / Option)
  • It doesn’t need to set up when DIGILOG gas meter connects to AMR device.
  • All-in-one system of reed switch and electronic display makes it easy to maintain.

    • min. Display : 0.01m3 (10ℓ)
    • Input Signal : LF(0.01㎥/Pulse)
    • Output Signal : Every signal for AMR / Option (DC-PLC, RS-485, TTL, PULSE, etc. )
    • Temperature Range : -20℃ ~ 60℃

Operating Principle

  • Gas Meter
    • Regulating gas is flowing into the entrance. And Gas is flowing into the measuring unit via the distribution chamber and circulation of valve.
    • By generating of differential gas pressure diaphragms are moving and it makes power to circulate valve. And then gas goes out via outlet. In the meantime, totalizer accumulate quantity of flow.
  • DIGILOG Ass’y
    • Mechanical index available with a permanent magnet in an index drum. Can be retrofitted with a low frequency pulse transmitter. (1rev. / 1Pulse)
    • Integrate quantity of flow per 1 pulse and display it through LCD monitor.
    • Can output information of quantity to AMR devices. (DC-PLC, Pulse, etc.)
