<p>The flowmeter has a side wall, which is formed by a liquid-tight printed circuit board. Measurement electrodes (10, 11) that are facing the circuit board are attached to an inner side of the flowmeter. Conducting paths and electronic components for executing and evaluating a conductance value measurement are arranged on the component-side of circuit board. The electrodes and conducting paths are connected through liquid-tight through connections (8, 9). Flow rate is calculated from the variations of conductance value measurement.</p> |
