Measure the bubble size, velocity and void fraction (gas fraction) at the heart of the flow !
Based on an innovative technique called Optical-Fiber Doppler Probe (OFDP), the M2 system enables easy measurement of bubble size and velocity in very dense flows, bubble columns, pipes or other liquid- gas environments with no optical access
Bubble size range: Down to 100 μm - No upper limit
Velocity range: 0.01 to 80 m/s
Void fraction range: 0 to 100%
Operating conditions:
Can work in environnements up to 250°C / 100 bar
Suitable for non-transparent liquids and turbulent flows
The Optical Fiber Doppler Probe technique designed by A2 Photonic Sensors is the fruit of more than 25 years of research. A micrometric sensor head is manufactured at the tip of an optical fiber. Once immersed in the flow, the optical fiber probe acts as both the laser emitter and light detector, and will measure all bubbles reaching its tip. The miniaturized size of the sensing part guarantees a very low disturbance to the flow, hence a high accuracy of the measurement.
