The KATflow 180 gives excellent results right down to atmospheric pressure, using ‘Lamb wave’ technology that makes accurate measurement possible even in metal pipes, including steel.

Gases dampen an ultrasonic signal far more than a liquid, making non-invasive flow measurement of gases more difficult. Katronic’s Lamb wave transducers are excited at the resonant frequency of the pipe material, making the pipe wall act as both emitter and receiver of the ultrasonic pulses, multiplying the effective transducer area for a higher signal strength and a better signal/noise ratio.

KATflow 180 is said to be better able to compensate for the attenuation of the gas. Katronic's advanced signal processing techniques analyse measured data and deliver an accurate measurement.
