Đồng hồ đo Gas Q.SONIC Elster

The Elster-Instromet multi-path Q.Sonic ultrasonic gas flow meter is ideal for the calibration measurement of natural gas. The patented measuring path arrangement, in conjunction with advanced ultrasonic sensors and digital signal processing allows high accuracy with excellent long time stability.
The flow profile analysis of the meter allows renouncing the usual adoption of a flow conditioner.

Q. Sonic - ultrasonic flow measurement with added value:
Single and double reflection technology combined to 3-path, 4-path or 5-path meters
Metrological identification of flow profile
High stability by digital signal processing (CMB)
Bi-directional use
Excellent repeatability
Excellent long-time stability
No moving parts, wear-free measurement
No pressure drop
Under pressure exchangeable ultrasonic transducers
