| PURPOSE: To measure the pressure in a pressure chamber together with the volume of the chamber by connecting a pressure sensor to the chamber. CONSTITUTION: A pressure chamber 15 is provided above a piston 13 and the chamber 15 is communicated with an injection nozzle 17 through a passage 16. Another passage 22 is formed in an acceptor 21 and the passage 22 is communicated with a solenoid valve 23. A hole 24 is branched off from the passage 22 and the hole 24 is communicated with a pressure sensor 25. In addition, a cable 26 is lead to an electrical measuring instrument from the sensor 25 and the stroke (h) of the piston 13 is also impressed upon the instrument through another measuring instrument in a pedestal 10 after the stroke (h) is converted into a signal. The stroke (h) varies depending upon the amount of a pressure medium injected into the chamber 15 through the nozzle 17 in one working cycle. The pressure medium causes the piston 13 to make the stroke (h). The values of both the stroke (h) and the pressure of the medium are evaluated in a suitable form in the electrical measuring instrument. Thus the pressure in the chamber 15 can be measured together with the volume. COPYRIGHT: (C)1990,JPO | ||||||

| PURPOSE:To correct humidity simply regardless of the change in relative humidity, by performing the flow rate measurement of only the gas in a wet gas, by correcting the temperature pressure of a dry gas and multiplying the result by a humidity correcting factor. CONSTITUTION:An operating and integrating flowmeter is constituted by the following parts: a flow-rate operating circuit 1, which receives a flow rate signal Sin and computes a flow rate; a dry air correcting circuit 2, which obtains a temperature pressure correcting factor K1 by K1=P/Pb.Tb/T (where P is the pressure of fluid, Pb is a reference pressure, Tb is a reference temperature, and T is the temperature of the fluid); a humidity-correcting-factor operating circuit 3, which obtains a humidity correcting factor K2 by K2=18.02/(HM+18.02), (where M is the molecular weight of the dry air and H is a mixing ratio); a correcting circuit 4, which performs the multiplications of the temperature-pressure correcting factor K1 and the humidity correcting factor K2; and an integrating circuit 5. The measured rate value is multiplied 4 by the factor K1 and the factor K2, which is based on the molecular weight M and the mixing ratio H of the wet gas. Therefore, the humidity can be corrected by the simple operation regardless of the change in relative humidity due to the change in temperature and pressure. | ||||||
| 124 | Nozzle for constant quantity discharging device | JP5001683 | 1983-03-24 | JPS59174720A | 1984-10-03 | SAITOU SUSUMU; MATSUDA CHIYUUICHI |
| PURPOSE:To obtain a contant quantity discharge device, which is not affected by the change in temperature, by providing a dual structure, wherein a material having a small thermal expansion coefficient is used for an outer pipe and a material having a large volume expansion coefficent is used for an inner pipe, and automatically changing the cross section of a nozzle hole in correspondence with the change in temperature of discharging fluid. CONSTITUTION:An outer pipe 2 is formed by using a material having a small thermal expansion coefficient such as Invar alloy and super Invar alloy. An inner pipe 3 is formed by a material having a large thermal expansion coefficient such as synthetic resin. A discharge pipe having a dual-tube structure is constituted by the two pipes. Even though the ambient temperature and the temperature of a liquid 4 are decreased, the nozzle is expanded to the inside by the amount of the volume expansion of the inner pipe 3, and the cross section of a nozzle hole 1 becomes small. Even though the viscosity of the liquid 4 is lowered as the result of the increase in temperature, discharge resistance is increased due to the decrease in the diameter of the nozzle hole 1. Therefore, the low viscosity and the discharge resistance are offset, and the amount of the discharge is hardly changed. A constant pressure is applied to the liquid 4 by a piston 6, and the constant quantity discharge can be performed. | ||||||

| PURPOSE:To perform simply and inexpensively highly accurate temperature correction in accordance with the difference of the specific gravity of LPG, by varying the actuation rate to a variable speed gear by adjusting the position of a temperature-displacement conversion part in accordance with the properties of liquid. CONSTITUTION:A rotary sliding plate 19 is supported with a pin 18 of a base board 16 and a temperature-displacement conversion part 20 provided with a temperature sensitive tube 13 is fixed piercing into the plate 19. The plate 19 is attached to a long hole 21 with a lock screw 23. A rotating lever 27 is abutted to a spindle 20a of the part 20 and an actuation element 10a of a variable speed gear 10. Now, when the temperature of LPG is varied, the spindle 20 is actuated and the temperature correction is carried out through the lever 27 by varying the rate of the variable speed of the gear 10. In case the specific gravity of the LPG is different, the plate 19 is approached to an axis 26 and the turning of the lever 27 is made quick at the time when the specific gravity is small and it is actioned reversely at the time when the specific gravity is large. For this reason, the correction of the specific gravity is performed by varying the turning angle of the lever 27 and varying the actuation rate of the gear 10 corresponding to the dimensions of the specific gravity. Hereby, highly accurate temperature correction is performed in accordance with the difference of the specific gravity. | ||||||

| PURPOSE:To prevent an error of flow rate due to vapor in fuel, by providing a flow rate sensor and a thermosensor to a fuel pipe and correcting the value of the flow rate from the flow rate sensor in accordance with a signal of the thermosensor. CONSTITUTION:A detection signal of a flow rate sensor 1 provided between a gasifying passage and a fuel pump is inputted into a microcomputer 16 through a waveform shaping circuit 14 and a detection signal of a thermosensor 15 for detecting a temperature of fuel in a fuel pipe is inputted into the microcomputer 16 through an AD converter 15. Vapor containing in the fuel pipe is increased with increasing temperature, and a real flow rate QM and a flow rate Q per one pulse from the sensor 1 are varied as curves A(T<=To), B(To<T<=T1), C(T1<T<=T2), D(T2<T) shown in the figure. Accordingly, each of the temperature curves A-D is selected in accordance with a signal of a thermosensor 2 by the microcomputer 16 and the flow rate in the fuel having no error of vapor is found by correcting the signal of the sensor 1. | ||||||

| The inline measuring device comprises a vibratory-type transducer and a measuring device electronics electrically coupled with the vibratory-type transducer. The vibratory-type transducer includes at least one measuring tube being inserted into the course of a pipeline and serving for conducting a mixture to be measured. An exciter arrangement acting on the measuring tube for causing the at least one measuring tube to vibrate and a sensor arrangement sensing vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers an excitation current driving the exciter arrangement. Further, the inline measuring device electronics is adapted to produce a measured value representing the physical, measured quantity of the mixture to be measured. Therefor, the measuring device electronics estimates from the excitation current and from said at least one oscillation measurement signal a Coriolis coupling coefficient. This Coriolis coupling coefficient corresponds with an instantaneous coupling between a first natural eigenmode of the measuring tube currently driven by the exciter arrangement and a second natural eigenmode of said measurement tube. In this second eigenmode the measurement tube has an eigenform corresponding with a mode of vibration caused by Coriolis forces induced in the flowing mixture. Due to a variation of a concentration of at least one of a component of the mixture the Coriolis coupling coefficient varies in time. | ||||||
