| <P>PROBLEM TO BE SOLVED: To provide a flow rate detecting method using a heat signal allowing accurate flow rate measurement by eliminating the factor of measuring error. <P>SOLUTION: In the flow rate detecting method using the heat signal, the heat signal of temperature variation is written into a medium moving in a flow channel 1, this heat signal is detected by a heat signal detecting means disposed at a position separated from a write-in position, and the moving speed of the medium is measured. A first temperature sensor 20A and second temperature sensor 20B of the heat signal detecting means are arranged on the downstream side of the write-in position at a predetermined interval L, and the moving speed is calculated based on the interval L and the difference between times when these two temperature sensors 20A and 20B detect the heat signal. <P>COPYRIGHT: (C)2007,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To make it possible to carry out accurate measurement with little disturbance, by detecting the resonance frequency or the change of amplitude with a resonator provided with a wire coil outside a feed pipe in a metal cylinder for obtaining the powder quantity. SOLUTION: A wire coil 44 which is a spiral or coil-like resonant member surrounding a feed pipe 10 is arranged in a shield metal cylinder 38 to form a microwave resonator 36. The resonator 36 requires a very little space, it guarantees high quality, and it can improve the measurement sensitivity of powder density. The coil 44 is formed on the thin film metal layer of the pipe 10. When the coil 44 is made of gold, its quality is further improved, and measurement sensitivity can be improved. The reference resonance frequency is detected on the known reference powder quantity, and two measurement frequencies are set on both sides of it. The resonance voltages of the powder quantity to be measured on these measurement frequencies are detected and compared, and the powder quantity per unit capacity is obtained from the potential difference.

| PURPOSE: To accurately detect speed and the direction of a conductive liquid medium even if a wall of a conductive material is arranged between a device and the medium by arranging a primary magnetic field and the acting direction of a measuring member at a right angle to a component of flow speed, and arranging the measuring member before and behind the flow direction. CONSTITUTION: A liquid medium flows through a primary magnetic field which is generated by constitutive members 2 arranged on an outside surface of a passage 1 and has plural spatial gradients. Constitutive members 4 to measure this magnetic field are arranged on an outside surface of the passage 1 on a plane 3 at a right angle to the lengthwise directional axis of the passage 1 between them and the members 2 so as to be opposed to the members 2. Signals of the members 4 are introduced by an evaluating unit 5. Flow speed can be directly regulated by mutual intervals of the members 4 and a time delay between continuous respective signals since heterogeneity of a flowing medium and the interaction with a generated magnetic field are almost simultaneously generated in the whole members 4. Therefore, motional speed and the direction of the medium can be accurately measured through a conductive constitutive part. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE:To measure a speed without any influence to an optical property of a substance by feeding a microwave to the substance transferred through a pipe at two points which are apart from each other and detecting a speed of the substance from a time difference of a modulation component of a reflected wave which receives an amplitude modulation by the substance. CONSTITUTION:The microwaves oscillated at microwave oscillators 6, 11 pass through circulators 7, 12 respectively, enter directional couplers 4, 5 and advance through a transferring pipe 1 in the same direction as a transferring direction A of the substance. A part of the wave reflected by the substance in the pipe 1 passes through the couplers 4, 5 and is made incident to detectors 8, 13 through the circulators 7, 12. A voltage of the modulation component of the reflected wave detected by the detector 8 becomes the voltage of a waveform shown in a figure (a) corresponding to a rough or dense state of the transferring substance. A voltage of the modulation component of the reflected wave detected by the detector 13 becomes the voltage of the similar waveform delayed by a timer tau for transferring the substance by the distance L. Accordingly, the transferring speed V of the transferring substance is detected by obtaining V=L/tau. | ||||||
