Application for Ultrasonic Gas Flowmeter :
Although industrial gas flow meters are widely utilised for liquid and water applications, it has long been accepted that clamp on gas flowmeter technology could not be applied to mass gas flow measurement primarily due to fundamental theoretical measurement limits. the transmitted sound energy is received by traditional ultrasonic transducers. However, advances in clamp on gas flow measurement technology and processing have meant that despite lower acoustic impedance levels and higher attenuation levels in most gases, a clamp on gas flow meter can now measure transit times in gases where signal-to-noise ratios are extremely low. It is now possible to measure natural gas, steam, compressed air, hydrogen, compressed air and many more using clamp on flow meters.A clamp on ultrasonic gas flow meter produces signals that are five to ten times more powerful than those of traditional ultrasonic transducers. The new clamp on transducers produce clean, coded signals with very minimal background noise. The result is that a clamp on gas flow meter can now provide optimum performance even with low-density gas applications.
