The ultrasonic meter calculates flow without mechanically moving parts by using the transit time of ultrasonic signals within the gas.
How the measurement works
Ultrasonic signals travel in two directions. The difference in transit time is used to calculate the flow velocity.
Advantages
It has no mechanical wear from rotating parts and can be used in high-precision applications.
Influencing factors
The quality of the flow profile, the cleanliness of the sensors, and the correct installation geometry affect accuracy.
Diagnostics
Many systems provide additional signal quality and status data, which are useful for predictive maintenance.
