    Miniature conductivity wire mesh sensor for gas-liquid two-phase flow measurement

  • Original language description

    A miniature conductivity wire-mesh sensor for gas-liquid two-phase flow measurement in small channels is presented. The sensor design is similar to the conventional wire-mesh sensor for larger flow cross sections with wire electrodes stretched across theflow channel in two adjacent planes and with perpendicular wire orientation between planes. Conductivity measurement is performed by special electronics which consecutively applies bipolar voltage pulse excitation to the sender wires and measures electrical current flow in the wire crossings at the receiver wires. The new design is based on printed circuit board technology. A prototypical sensor made of 2 x 16 stainless steel wires each of 50 mm diameter was manufactured and applied to two-phase flow measurement inside the mixing chamber of an effervescent atomizer. Accuracy of the sensor was studied for static liquid distributions using microphotography and for dynamic two-phase flow by comparison of wire-mesh sensor data with radial

    Miniaturní vodivostní sensor s drátovou sítí pro měření proudění ve dvoufázových směsích kapalina-plyn

  • Czech description

    V článku je prezentován nový miniaturní vodivostní sensor s drátovou sítí pro měření proudění ve dvoufázových směsích kapalina-plyn. Sensor je tvořen mřížkou kolmo na sebe orientovaných drátů průměru 50 um. Fáze v blízkosti křížení drátů je detekována podle elektrické vodivosti. V příspěvku je popsána aplikace senzoru a iověření jeho přesnosti.
