| The invention relates to a converter for providing a liquid at a measurement pressure corresponding to a revolution speed of a journal (2) rotating about an axis (1), in a measuring line (3). The journal (2) is fitted to slide in a fixed housing (5) and has a drilling (7) from one end (6) along the axis of rotation (1). The housing (5) has a first groove (9) surrounding the journal (2) which communicates with the drilling (7) via at least one transverse drilling (12) in the journal (2). The converter has a flow path for the liquid connectable to a tank (10) under a primary pressure on one side and to an unpressurised trough (8) on the other side which flow path comprises the first groove (9), the transverse drilling (12), the journal drilling (7) and a choke (11) and from which the measuring line (3) branches off between the transverse drilling (12) and the choke (11). According to the invention, the choke (11) is a gap (11) between a component (5, 24) rigidly secured to the housing (5) and the journal (2). Between the tank (10) and the tough (8) is formed a balance of flow depending on the revolution speed which determines the measuring pressure in accordance with the rotation speed. The converter is particularly suitable for controlling the rotation speed of a steam turbine (15), the journal (2) being fittable directly on a drive shaft (14) of the steam turbine (15). | ||||||

| The present invention discloses an improved system for measurement of the liquid flow rate and totalized liquid production of a producing well. In the method of the present invention, liquid production rate in a pumping well is determined by calculation based upon wellbore geometry and continuously monitoring the depth of the fluid level within the wellbore. It is applicable to any pump lifted well where it is possible to shut the pump off periodically. Accuracy is enhanced with this method by properly accounting for pump leakage and where pump leakage is either known or can be estimated within reasonable limits or where it is measured during the pump shut off cycle. | ||||||

| PURPOSE:To enable the measurement of an appropriate speed irrespective of limit of an installation space and a low-speed drive of a device in a hydraulic drive system, by a method wherein a low-capacity type hydraulic motor is located in the middle of a hydraulic circuit, and meters are connected to the low- capacity type hydraulic motor. CONSTITUTION:A hydraulic drive vehicle 1 is provided with a running drive system A ranging from a running engine 2 to a transfer 4 via transmission 3, and a hydraulic drive system B extending to the transfer 4 through a hydraulic motor 6. A low-capacity type hydraulic motor 7 is situated in the middle of a hydraulic circuit 8 consisting of a hydraulic pump 5 and a hydraulic motor 6. Even in case the pump 5 and the hydraulic motor 6 turn at a low speed, the motor 7 runs at an enougly high speed, and a speedometer 9 operates in synchronism with the low-capacity type hydraulic motor 7. This constitution causes the speedmeter to response accurately even if oil in the hydraulic circuit is brought to a comparatively less amount. Thus, even in the case of a low-speed drive, an appropriate measurement can be performed. | ||||||

| PURPOSE: To facilitate detection of a rotational speed so as to improve accuracy by providing an oil pressure vibration detecting means of oil pressure from an oil pump and an input rotational speed arithmetic means for calculating a transmission input rotational speed based on a signal of the oil pressure vibration detecting means. CONSTITUTION: A pressure sensor 99 is provided in a delivery pressure circuit from an oil pump, and a signal from this sensor is input to a control unit 300. In an input interface 311 of the control unit 300, a DC component of the signal obtained from the pressure sensor 99 is cut off, next a primary component of oil pressure vibration is detected and input to a central processing unit 313 by shaping a waveform of this primary component. The central processing unit 313 judges that an input rotational speed is one rotation per 9-pulse, in the case where the number of vanes or gear teeth of the oil pump is 9, and obtains the input rotational speed based on this judgement. An oil pressure is vibrated, and the oil pump is judged to have made one rotation in the case 9 waveforms are counted. COPYRIGHT: (C)1992,JPO&Japio | ||||||

| PROBLEM TO BE SOLVED: To provide a method and a system capable of easily and accurately measuring revolution of a pump motor. SOLUTION: This measuring system is provided with a pressure sensor on a pump delivery valve and composed so that a signal of the pressure sensor is supplied to a comparator (2) through a high-path filter (1), a threshold of the comparator (2) is adjustable as a function of temperature (T) for a pump vehicle, and an output of the comparator (2) is returned into an input of the comparator (2) through a delay circuit (3) to be supplied to a timer (4) counting cycles of the comparator (2) output signal. Thus the pump delivery valve measures a pressure signal (P) to determine the spacing proportional to the revolution between adjacent pressure pulses exceeding definable threshold, inhibits pressure fluctuation of high frequency generated between the above pressure pulses and also allows the above threshold to be adjusted as the function of temperature (T) for a pump vehicle, measuring revolution of the pump motor.

| A converter assembly for providing a liquid in a measuring line includes a stationary housing and a component being rigidly connected to the housing. A journal is slidingly supported in the stationary housing and defines a gap disposed between the component and the journal forming a throttle. The journal has an axis of rotation, an end, at least one transverse bore formed in the journal, and a journal bore formed in the journal from the end along the axis. The housing has a groove formed therein surrounding the journal and communicating with the journal bore through the at least one transverse bore. A liquid flow path communicates with a reservoir at a primary pressure and a pressureless sump and includes the throttle, the groove, the transverse bore and the journal bore. A measuring line branching off from the path between the transverse bore and the throttle carries the liquid at a measurement pressure corresponding to a rotational speed of the journal rotating about the axis. | ||||||
