Tribosonics Ltd., in conjunction with HMD Sealless Pumps, has developed novel ultrasonic technologies capable of detecting the presence of gas within a liquid or substrate.
These gas detection technologies offer several key advantages:
The technologies work on the principal that larger bubbles will scatter an ultrasonic wave, while the presence of smaller amounts of dissolved gases will change the bulk properties of a liquid. Either of these mechanisms can be detected using the BD003 gas detection unit.
An ultrasonic transducer is mounted on the external surface of the component or pipe carrying the liquid. An ultrasonic wave is then sent through the liquid and picked up either by the original transducer, as a reflection, or by a secondary transducer. The recieved signal is processed in real-time and the proportion of gas present is output, either to your control systems via 4-20mA control loop, or stored on-board.
Aeration is the process by which a gas is mixed with a substrate, typically a liquid. Such processes are performed in diverse range of applications from carbonating soft-drinks to biological waste water treatment.
Cavitation is the formation of bubbles or cavities in a liquid. This is commonly occurs where a sharp pressure gradient is seen, this can cause gaps to form in the liquid due to the relatively low pressure. Cavitiation can cause excessive wear which is a major problem in a range of engineering applications.
