Q.Sonic Ultrasonic Gas Meters

Q.Sonic Ultrasonic Gas Meters
Fiscal · multi-path · no moving parts

Multi-path ultrasonic gas meters (AGA-9 / ISO 17089) with full diagnostics — zero pressure drop, no moving parts, a forty-year service life.

Measurement is based on the transit-time difference of ultrasonic pulses traveling with and against the flow. No moving parts means no wear, no pressure drop, and rich measurement-state diagnostics.

Supplied with a volume converter and a full diagnostic report — fiscal (custody transfer) class.

FTMeasuring principle

Transit time of ultrasonic pulses.

Pulses cross the pipe on a diagonal path — once with the gas flow, once against it. With the flow they arrive sooner; from the difference in transit time the meter electronics derive the flow velocity and, from it, the volume flow. The film shows one path — Q.Sonic measures on 5, 7 or 10.
