The Katronic KATflow 180 clamp-on flowmeter for gases is ATEX approved and has the ability to perform clamp-on measurement of gaseous flow at low pressures and in metal pipes.

Clamp-on measurement of gas has, typically, been limited to high pressures, plastic pipes and ‘ideal’ installations. The KATflow 180 gives results right down to atmospheric pressure even in metal pipes, including steel.

A gaseous medium dampens an ultrasonic signal far more than a liquid, making non-invasive flow measurement of gases far more difficult. The effect reduces as pressure increases, resulting in a 5 bar lower pressure limit at which conventional transit time measurements using shear waves can be made. 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-to-noise ratio.

A stronger signal means that the KATflow 180 is better able to compensate for the attenuation of the gas, and Katronic has developed advanced signal processing techniques to analyse the measured data and deliver an accurate measurement.

The KATflow 180 is able to measure in pipes from 25 mm to 1.5 m diameter, with flow rates of 0.1 to 75 m/s and pressures of 1 bar up to unlimited maximum. It is designed to be capable of being mounted permanently in an ATEX Zone 1 or 2 hazardous area, with a robust housing and non-intrusive programming.
