摘要： PURPOSE: To eliminate the discontinuity of display by measuring the intermediate and large flow rates by a fluidic oscillator based on the oscillation period of the oscillator, and by eliminating a complicate calculation upon switching to measure by a flow sensor in a small flow rate range to calculate by following up the change of the flow rate. CONSTITUTION: The fluid vibration of a fluidic oscillator is detected by a piezoelectric film sensor 1 to an electric pulse. The electric pulse is volume-converted by a volume converter 8, and stored in an intermittent processing buffer 18. The signal of a flow sensor 3 is volume-converted, then cancelled at forward and reverse flows, and simultaneously transferred to a arithmetical buffer 20 together with the content of the buffer 18 at each time to match the intermittent drive of the sensor 3. Thereafter, it is divided and output by a smoothing processor 21, and continuously displayed by a display unit 17.

摘要： PURPOSE: To alleviate the measuring error due to the insufficiency of the signal of a fluidic oscillator 'the missing of a pulse' or the excess of a signal 'whisker' of the oscillator when a supply gas pressure is varied. CONSTITUTION: The fluid vibration of a fluidic oscillator is detected by a pressure sensor 10, and shaped to a square wave by a waveform shaper 17. The period of the signal is measured by a period measuring unit 18, compared with a previously decided threshold coefficient, and its varying trend is sequentially obtained. The 'missing of a pulse' or a 'whisker' is recognized from the trend to interpolate the 'missing of the pulse' or the 'whisker'. A changeover switch 27 is operated by the interpolated signal to select the signals from the sensor 10 and a flow sensor 12.

摘要： PURPOSE: To obtain a fluidic flowmeter in which the measurement is insusceptible to the presence of a bypath. CONSTITUTION: The fluidic flowmeter comprises a target disposed in the downstream of a flowmeter section 37 and shunting a fluid to generate pressure oscillation therein, a differential pressure sensor for measuring the pressure of the fluid shunted by the target, and means for calculating the current velocity based on the frequency of pressure oscillation of the fluid measured by the sensor. A partition plate 35 disposed in the upstream of the flowmeter section 37 shunts the fluid to the flowmeter section 37 and a bypath 36 and a straightener mesh 22 is fixed at a port where the shunted fluids are combined.

摘要： PURPOSE:To lessen the undesirable effects of dusts flowing together with gases in a pipeline. CONSTITUTION:All gases taken in through an inlet part 11 of a fluidic flow meter come into collision against a magnet 51 installed immediate behind the inlet part 11 and flow to the down stream side through a space between a main body 10 composed of spacers 52 and the magnet 51. At that time, magnetic metal components, which are main components of dusts flowing together with the gases, are captured by the magnet 51 and inhibited from flowing to the down stream side. Meanwhile, the gases which pass the space between the main body 10 and the magnet 51 pass a first gas flow route 14, an open part 16, a second gas flow route 15, and a flow rectifiying member 22 in this order and go into a nozzle 21.

摘要： PROBLEM TO BE SOLVED: To accelerate the operating speed of the flow-speed converging data of a flow sensor. SOLUTION: In a graph which indicates the relation between an output value S of a flow sensor and a flow speed V of fluid by the beforehand regression with a curve 18, a point 20 corresponding to the maximum output value and a point 21 corresponding to the minimum output value are connected with a straight line 19. A point which is remotest in the perpendicular direction with respect to the line 19 on a regression curve 18 is made to be a first dividing point 23. The straight line 19 is divided into two parts at the first dividing point 23. By the same way, the straight line is sequentially divided, so that the approximate folded line is obtained. These values are stored in the memory device in the controller part as the flow-speed conversion data.

摘要： PROBLEM TO BE SOLVED: To obtain a high operation speed for flow rate conversion data of a fluidic flowmerter. SOLUTION: In a graph showing a relationship of an oscillation cycle T and flow rate conversion coefficient P of a fluid, a measuring point 20 corresponding to a maximum oscillation cycle and a measuring point 21 corresponding to a minimum oscillation cycle are connected by a straight line 19. Among the measuring points, a measuring point separated most from the line 19 in an orthogonal direction is set as a first dividing point 23. The line 19 is divided half at the first dividing point 23. The line is sequentially divided in the same manner, thereby to obtain an approximate polygonal line which is stored as flow rate conversion data in a memory device within a control part of a flowmeter.

摘要： PROBLEM TO BE SOLVED: To provide a gas flowmeter which correctly calculates the gas consumption amount of a gas piping in a predetermined time with the use of a program of simple contents even when the gas flow rate of the gas piping pulsates due to the use of gas of a gas appliance. SOLUTION: Whether or not a sampling interval (t) has passed is judged (S1). When it is judged that the sampling interval (t) has passed (S1: YES), it is waited until the gas pressure of a gas piping becomes a stationary value on the basis of an output of a pressure sensor fixedly set in the gas piping (S2). When it is confirmed that the gas pressure of the gas piping is a stationary value, a gas flow rate sensor fixed in the gas piping is driven (S3). The gas flow rate of the gas piping is calculated from an output of the gas flow rate sensor (S4).

摘要： PROBLEM TO BE SOLVED: To provide a gas flowmeter wherein the gas consumption by a specific gas equipment is judged by a simple method, when the consumption of a specific gas equipment and that or a normal gas equipment are individually accumulated based on such judgement as there exists gas consumption by a specific gas equipment such as gas engine heat pump. SOLUTION: In a pressure sensor 21, an analogue output part 21a which outputs an analogue signal corresponding to fluctuation in gas pressure within a gas piping 14 and a digital output part 21B which outputs a digital signal corresponding to the fluctuation in gas pressure within the gas piping 14 are provided. At a gas engine heat pump(GHP) consumption judgment program 36, using such simple method as a comparison of the fluctuation width in gas pressure fluctuation which is directly obtained from the output of the analogue output part 21A to a first regulation value and a comparison of the cycle in gas pressure fluctuation which is directly obtained from the output of the digital output part 21B to a second regulation value, the presence of gas consumption of GHP as a specific gas equipment is judged.
