    Abstract: Un método de uso de accesos de lavado por descarga (1A, B) cuando se limpia un acumulador de pistón (7), en el que se fuerza aceite hidráulico limpio al interior del acumulador de pistón (7) por medio de los orificios axiales (3A, B) de los accesos de lavado por descarga (1A, B) y además en unos orificios en pendiente (3C, D), llevando el aceite hidráulico al interior del volumen (8) de tal modo que este se encuentre con la pared interna de cilindro (10) y el lado inferior del pistón en una dirección tangencial hacia arriba por debajo del pistón (5), en una circulación de lavado por descarga, y devolviéndose aceite hidráulico sucio al exterior por medio de un acceso principal (2) y un paso de retorno (9) hasta que se haya alcanzado un grado de limpieza, caracterizado por que mediante la reducción de la presión de gas en el lado de gas (4) de un pistón (5) en relación con la entrada de presión de lavado por descarga a partir de una válvula (6), se crea un volumen (8) en el lado de aceite entre el pistón (5) y la parte inferior extrema (3); por que el paso de retorno (9) se cierra y el pistón (5) se lleva a su posición superior, de tal modo que se limpie una pared interna de cilindro (10), y por que con la acumulación de presión, el paso de retorno (9) se abre y el pistón (5) vuelve a su posición extrema en el lado de aceite mientras que se mantiene el suministro de aceite hidráulico limpio, y la operación se repite hasta que se haya logrado un grado de limpieza.

    Abstract: The invention relates to a downhole pressure- and vibration- measuring device integrated in a pipe section (1) as part of a production tubing (20). The sensor housing (2) of the measuring device with sensors has a two-part clamp (3) on the upper part of the sensor housing (2), from where an electrical multi- conductor cable connection (10) from at least four, preferably six, nipples in a tube (9) is clamped along the production tubing (20) with bushings through equipment installed in the wellhead to sensors with an electronics and control unit (12) above the wellhead. Evenly- spaced radially in an annular space (5) are a first set of strain gauges (7) attached to the outside wall of the production tubing (20) and a second set of strain gauges (8) attached on the inside of the external wall of the sensor housing (2). Strain gauges (7, 8) are connected by glass penetrators (4) of electrical conductors in cable tubes (9A) terminated in the tubing hanger (21) to an electronics unit (11) and a control unit (12). For the measuring of temperatures, a thermometer will be integrated. Pressure -measurement signals also measure vibration in the production tubing (20).

    Abstract: The invention relates to a method for measuring and controlling a fluid flow in a pipe system for liquid transport, such as oil flow during buoy loading, wherein there in each end of a the pipe system is spliced in a sensor (1) consisting of a pipe section (2) with a reinforced rubber bellows (3) positioned as a restriction within the transport pipe. The rubber bellows (3) is forced radially outward when there is oil flowing through the transport pipe, and compresses a gas filled volume in a pressure vessel (4) via a pipe connection (4B) in communication with an annulus (5), and a pressure transmitter (6A/B) gives signals to a control system (7). The sensor (1) on the platform and the tanker vessel measures relative changes in the liquid flow between the two measuring points, as the measurements from the tanker vessel is received via a telemetry system, and the signals from the two measuring points are compared continuously by the control system on the platform, which triggers an alarm and shuts down the loading process automatically at deviation in the measurement on the tanker vessel compared to the reference measurement on the platform.
