| <P>PROBLEM TO BE SOLVED: To miniaturize a flow control device and to reduce the facility cost by enabling accurate flow control of a fluid in a further wide flow area by use of one flow control device. <P>SOLUTION: The pressure type flow control device is adapted to calculate the flow rate of a fluid passing through an orifice 8 using an orifice upstream pressure P<SB>1</SB>and/or an orifice downstream pressure P<SB>2</SB>as Qc=KP<SB>1</SB>(K is a proportionality factor) or Qc=KP<SB>2</SB><SP>m</SP>(P<SB>1</SB>-P<SB>2</SB>)<SP>n</SP>(K is a proportionality factor, and m and n are constant numbers). In this pressure type flow control device, a fluid passage between the downstream side of a control valve and a fluid supplying conduit is formed of at least two or more parallel fluid passages, and orifices differed in fluid flow characteristic are interposed in the parallel fluid passages, respectively. The fluid in a small flow area is distributed to one orifice in flow control of the fluid in the small flow area, and the fluid in a large flow area is switchingly distributed to the other orifice in flow control of the fluid in the large flow area. <P>COPYRIGHT: (C)2007,JPO&INPIT | ||||||

| PURPOSE:To obtain approximately the same output under the same conditions, by providing the inlet opening part of a bent pipe in the direction, which does not receive the dynamic pressure of an intake air flow with respect to the axial line of a Venturi part, and guiding a static pressure to the inlet opening part of the bent pipe. CONSTITUTION:An inlet opening part 18 of a bent pipe 12 is opened at a clearance angle theta as shown by a cutting line D with respect to an axial direction line C of a Venturi part 3. The intake air flows along the axial direction line of the Venturi part 3, but the inlet opening part 18 of the bent pipe 12 does not receive the dynamic pressure of the intake air flow. Therefore, the output of a heat sensitive resistor, which is arranged in a bypass air path 8 of an air flow rate detecting device, becomes approximately the same under the same conditions. | ||||||

| PURPOSE:To enable the flow rate control and the flow rate measurement to be simultaneously performed, by providing a cylindrical body provided with a flow rate curve to a rod which can vary the sectional area of a through hole in a main pipe having a by-pass including a tapered tube. CONSTITUTION:A valve 3 in which a through hole 2 has been bored is closely fitted into a main pipe 1, and a by-pass 7 which has a float 4 floating therein and includes a tapered tube 6 having a small hole path 5 is made to communicate with the main pipe, in front and the rear of the valve 3. Moreover, the valve 3 is provided with a rod 8 projecting therefrom and having a handle 9 provided with graduations showing the opening area of the through hole 2. When it is open, a differential pressure is provided between in front and the rear of the valve 3. Consequently, the float 4 in the tapered tube 6 is floated by the fluid Q flowing through the by-pass 7. Therefore, providing a flow rate curve 16 showing the relationship among the opening area (a) of the hole 2, the floating stop height H of the float 4 and the flow rate Q to a cylindrical body 15 secured to the rod 8 permits the flow rate to be obtained from the stop position of the float 4. | ||||||

| The flow measurement having a substantially cylindrical housing (12) with a valve element connected to an inner surface thereof. The valve is movable between an open position and a closed position in the bore (14). A secondary flow passageway is formed in the housing and extends along the longitudinal axis of the housing. A first end of the secondary flow passageway is in fluid communication with the bore below the valve element. A flow measuring device (10) is located near a second end of the secondary flow passageway for measuring the rate of fluid flow therethrough. The housing is adapted to be connected at each end thereof to well tubing. The present invention provides a flow measurement mandrel that diverts the production flow the secondary flow passageway by closing a hydraulically operated flapper valve and routing the fluid or gas through a venturi flume in the secondary flow passageway for flow measurement. After monitoring flow rate, the flapper valve is re-opened and full bore production is achieved. | ||||||

| A particle sensor uses an electrostatic particle charging section in the form of an ionization chamber. A flow sensor arrangement is used to produce a signal which is representative of the amount of gas flow between the outside of the ionization chamber and the inside of the ionization chamber. This information is indicative of the flow conditions, and can be used to determine when adverse flow conditions are present which may adversely affect the performance or lifetime of the particle sensor. | ||||||
