Hitachi S²Sonic – Ultrasonic Gas meter

 

Highly Accurate Flow Measurement

Adopts the propagation time difference system. The time difference of the ultrasonic waves varies in proportion to the flow speed when the pair of sensors alternately and repeatedly emit and sense signals

Features

High Accuracy / Wide Flow Range

  • High-accuracy (±1% RD (meter units))
  • Wide measuring range (flow rate range 1:40, flow rate sensitivity 1/200)
  • Maximum flow speed: 30 m/s, sufficient for measuring town gas

No Moving Parts / No Obstructions

No protrusions in the flow path mean little pressure loss and no supply failure in the event of an unexpected malfunction.

Dust- / Mist-Resistant

Meter operation is hardly affected by dust, mist or other foreign matter in gas piping.
