Title:
METHOD OF AND APPARATUS FOR MEASURING FLOW VELOCITY
Document Type and Number:
Japanese Patent JPS5643559
Kind Code:
A
Abstract:
A device for measuring the velocity of flow of a fluid comprises a length of pipeline through which the fluid flows. A first resistance is mounted to extend across the pipeline at a first point and is supplied with periodic input pulses by a pulse generator such that the temperature of the first resistance is caused to rise periodically. A second resistance is mounted to extend across the pipeline at a second point which is spaced downstream of the first point. The second resistance has a value which varies with temperature and produces an output signal when it detects fluid heated by the first resistance. A circuit measures the time between an input pulse and the corresponding output signal such that the velocity of the flow of the fluid can be determined.
