Wavelet analysis of test signal from conductivity probe on single bubble-cap tray plate;

The local gas holdup in a bubble column(476 mm) was measured by dual conductivity probes.

The connection between air-water two-phase on bubble-cap plate was investigated experimentally by using the double-sensor conductivity probe.

The time-dependent liquid film thickness in horizontal and slightly inclined tubes was measured by using parallel-wire conductance probes,and various wave patterns were obtained.

A conductance probe including an injector to inject the electrolyte tracer into the flow was designed to measure local liquid velocities in gas-liquid two-phase flows.

For the identification of gas/liquid two-phase flow in vertical upward pipe,a kind of measuring system with multiple conductance probes was presented,of which conductance sensors was composed by three conductance probes,and data acquisition of conductance fluctuation signals came true by using INV306 data collection card on the basis of measuring system.

To study the flow regime of gas-liquid two-phase in vertical upward pipe,the conductance fluctuation information of four typical flow regimes was collected by measuring system with self-made multiple conductance probes.
