Application of Ultrasonic Flow Measurement for Gases
When we took the decision to begin the development process of a new gas clamp-on ultrasonic flowmeter we had two clear goals in mind: To be able to provide accurate and reliable flow measurements, and to do so on applications where other existing instruments would not. From that point forward the focus has been on not just developing a technology as good as what was available on the market, but something that took the industry to a new level. The gas flowmeter retains many of the popular features of the flow range such as the robust design, ease of use and high quality sensors but marries this with entirely new ultrasonic hardware. This new generation of instrument was required in order to meet the exacting targets set by the company when measuring a more demanding medium varying conditions.As well as pushing the boundaries of ultrasonic technology we have also taken an innovative approach to sensor design. We did this to achieve a dual-mode gas flow metering capability using the fewest sensor combinations thereby reducing both complexity and cost. We can offer both shear wave and Lamb wave measurement to cover the widest possible range of requirements.
