Abstract
PURPOSE: To reduce power consumption and simplify construction by a method wherein a coil generation body generating a coil line in proportion to fluid speed and an electrode adjacent to the position to be affected by its influence is providd, a fluctuation period of drifting voltage generating from the electrode is detected to seek a flow rate.
CONSTITUTION: An internal wall of a conduit 1 consisting of a metallic pipe and as a steel pipe is given a lining layer 3 to insulate the electrodes 2a, 2b through said lining layer. The upper stream side thereof is provided with a coil generating body 4 consisting of a cylindrical body. The drifting voltage generating from the electrodes 2a, 2b is amplified to a fixed level by a head amplifier 7, automatic gain control amplifier 8. Its output is transferred to a period measuring device 11 through a variable filter 9, corrugated shaping circuit 10 to measure the fluctuating frequency of drift voltage and to fix flow. Consequently the small power consumption and simple construction leads to low-priced making.
