Title: Flowmeter
Inventor: YOSHIMURA NORIYUKI
IPC: G01F1/22
Filed: 1994-02-25
Abstract: PURPOSE:To provide a flowmeter in which a subtle variation of flow rate can be measured by providing a float incorporating a resonance circuit and applying an excitation detecting coil for detecting the position of the float over a tapered pipe thereby obtaining a lightweight compact float and to prolong the service life of flowmeter by eliminating the frictional part. CONSTITUTION:A muCPU 7 selects a coil L1, for example, among excitation detecting coils L1-Ln and an excitation signal is applied from an exciting circuit 4 to the coil L1 through a switch 6. When the coil L1 is separated from a float 2 and not coupled electrically with a resonance coil L0, the current flowing through the coil L1 is determined only by the self inductance. When a coil L2 proximate to the float 2 is selected, the coil L2 is coupled electrically with the resonance coil L0 and an electromotive force is induced in the secondary coil, i.e., the coil L0. Consequently, the current flowing through the primary coil, i.e., the coil L2, increases. The increment of current is measured and jnterpolated thus detecting the position of the float 2.
