| PURPOSE: To minimize force of a spring holding a valve head in the closing position and to shorten its length by using a very narrow main flow packing sheet, providing a pan-shaped edge in a shutting off mechanism, and narrowing a ring type chamber side face conically. CONSTITUTION: When a differential pressure is increased further in compliance with increase in quantity of water flowing through an auxiliary pipe, a shutting off mechanism 9 starts moving against the force of a compression spring 12, while an elastic lip packing 27 is still closed. However, a pan-shaped edge 17 of the mechanism 9 reaches the center of a slit zone 51 through a neutral zone 14. In this process, an auxiliary flow shifts the edge 17 into a conical weir stepped part, 52. In this case, a narrow width ring slit 20 between the edge 17 and a ring type chamber side face is continuously reduced. Therefore, the edge 17 moves to end part back side of the stepped part 52, the packing 27 is separated from a sealing edge 49, and the main flow water passes through a main water measurement device 1 and a main flow penetrating zone 22. This opening process is carried out very quickly, so that no measurement error is generated. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: To measure a wide range of flow rate with good accuracy by providing a flowmeter of a thermal flow velocity sensor type and a correcting flowmeter in a flow passage, and correcting the measured value of the flowmeter in accordance with the measured value of the correcting flowmeter in a predetermined range of the flow rate. CONSTITUTION: A flowmeter 1 of a thermal flow velocity sensor type and a Karman vortex flowmeter 2 as a correcting flowmeter are provided in a flow passage 11. The measured value of the flowmeter 1 input through a first driving circuit 3 is integrated or multiplied in an integrating/multiplying circuit 6 of a control part 5. Moreover, the measured value of the flowmeter 2 input through a second driving circuit 4 is integrated or multiplied in an integrating/ multiplying circuit 7. A predetermined correction is performed on the basis of the outputs from the circuits 6, 7. At the same time, the circuits 3, 4 are controlled on the basis of the outputs of the circuits 6, 7. An output signal is output from a correcting/outputting circuit 8. In this manner, even when the composition of a gas is changed, the flowmeter of a thermal flow velocity sensor type can be used as a volume flowmeter in a wide range with high accuracy.

| PURPOSE: To realize the composite flowmeter of a small-sized and simple structure by combining a Karman's vortex flowmeter for measuring a flow rate of a high flow rate area and a microbridge sensor for measuring a flow rate of a low flow rate area. CONSTITUTION: A composite flowmeter for measuring a flow rate of a fluid flowing in the direction as indicated with an arrow F consists of a microbridge sensor 1 and a Karman's vortex flowmeter 2a, and as for a high flow rate area, a flow rate is measured by the Karman's vortex flowmeter 2a, and as for a low flow rate area, a flow rate is measured by the microbridge sensor 1. In such a way, since the microbridge sensor 1 and the Karman's vortex flowmeter 2a whose structure is simple and small in size are combined, this composite flowmeter becomes smaller than a conventional composite flowmeter formed by combining with a fluidic flowmeter, and also, the microbridge sensor 1 can be attached easily, and accordingly, the cost is reduced. Moreover, by correcting an output signal value of the microbridge sensor 1 by an output signal value of the Karman's vortex flowmeter 2a, the continuity and the accuracy of an output signal can be held.

| PURPOSE: To obtain a compact flowmeter by measuring the flow rate of fluid by coupling the outputs from two out of three detection means and obtaining an error signal to be employed for recalibration of measurement by coupling the outputs from three detection means. CONSTITUTION: A flowmeter 36 provided for a bypath 33 comprises a recalibration circuit to be mounted internally or externally, a density transducer 37, a microbeam flow sensor 38, and a pure fluid flowmeter 39. The density transducer 37 is set in the dead zone of bypath 33 substantially containing a stationary fluid and surrounded by a fine filter 40 so that the surrounding fluid is kept stationary. Flow rate of the fluid is then measured by coupling the outputs from the sensor 38 and transducer 37. Furthermore, an error signal to be employed for recalibration of measurement is obtained by coupling the outputs from the flowmeter 36 additionally. COPYRIGHT: (C)1989,JPO | ||||||

| PURPOSE:To measure the flow rate accurately regardless of the magnitude of the flow rate, by arranging a plurality of flowmeters having different measuring ranges in series in the flow of liquid, and bypassing only the required flowmeter in response to the flow rate. CONSTITUTION:For example, when the flow rate is 80m<3>/min or less, a flow rate regulating valve 5 is closed, the entire liquid flows in the first flowmeter 1, and the flow rate is measured. Meanwhile, when the flow rate exceeds 80m<3>/ min, the valve 5 is opened, and the fluid which is joined with the fluid through a bypass pipe 4 is measured by the second flowmeter 3. By the arrangement of the flowmeters in response to the flow rate, the flow rate up to 5,000m<3>/min is accurately measured in the entire range. | ||||||

| PURPOSE: To obtain a wide range of measurement without being restricted by the fluidity of the fluid to be measured by combining the heating metal wire for detecing Kalman's vortex with a function of a hot-wire current meter. CONSTITUTION: Heating metal wires 5 and 5' serving as a hot-wire current meter are provided behind a vortex generator 4 provided in the suction tube leading to the engine. The output of the metal wires 5 and 5' is inputted into the hot-wire circuit section 9 in such a manner that the electric signal VDC is outputted from the output terminal A corresponding to the hot-wire current meter while the AC signal VAC is outputted from the out terminal B corresponding to the Kalman's vortex current meter. When the suction tube 2 is under a fixed vacuum, that is, the sucking pulsation is large, the switch 11 is activated to halt the action of the 12. The output V 1 of the hot wire current meter is produced by the signal selection circuit 14. When the sucking pulsation is small, the switch 11 fails to work. Thus, the calibration device 12 calibrates the output V 1 of the hot-wire current meter while the output V 2 of the Kalman's vortex current meter is produced from the signal selection circuit 14.
