Wire-mesh sensors are imaging instruments for the analysis of gas-liquid and liquid-liquid multiphase flows. They combine a robust design, secure phase discrimination and ultrafast measurement. Wire-mesh sensors allow you to visualize and measure transient flows with unprecedented frame rates of up to 10,000 images per second and up to 2 mm spatial resolution and thus to disclose even the last unresolved detail of your flow problem.



How the Wire-Mesh-Sensor works

Wire-mesh sensors measure characteristic multiphase flow parameter by a grid of fine wire electrodes in the flow cross-section. The wires are very thin, typically 0.25 mm. Thus the sensor generates virtually no pressure drop. Usually, wire-mesh sensors are operated in pipes or columns. But special designs also allow the investigation of other flow cross-sections. If round or square, small or large – wire-mesh sensors offer all the required flexibility.

Measurement method

Wire-mesh sensors employ an electrical measurement principle for the differentiation of the individual phases in the flow. By choosing between conductivity or capacitive measurement scheme you may analyze virtually any solids-free type of multiphase flow. Examples are water-gas, water-steam and oil-gas flows.
