    • An oscillating jet type of fluidic flowmeter, for use as a domestic water meter, is provided with a conditionning disc (6) at its entry to increase the linearity of the meter. The disc is mounted upstream of an elongate jet-forming orifice, being at the mouth of a convergent entry passage leading into the orifice. The disc can be in the form of a slotted plate, having three slots (12) separated by elongate bluff blocking regions (13), the slots and blocking regions being in parallel with the jet-forming orifice. The conditioning disc has the effect under laminar and transitional inlet flow conditions of flattening the velocity flow profile and introducing turbulence into the flow, whereby fully developed turbulent flow conditions become simulated at the orifice.
    • 用作家用水表的振荡射流型流体流量计在其入口处设置有调理盘(6),以增加仪表的线性度。 盘安装在细长喷射形成孔的上游,位于通向孔口的会聚进入通道的口部。 盘可以是开槽板的形式,具有由细长的非截流阻挡区域(13)分开的三个槽(12),所述槽和阻挡区域与喷射形成孔平行。 调节盘在层流和过渡入口流动条件下具有平坦化速度流动分布并将湍流引入流中的作用,从而在孔口处模拟完全发展的湍流条件。

    • Disclosed herein is a processing station (10) for registering a passenger's luggage for a trip. The processing station (10) comprises an injector (14) for receiving a piece of luggage associated with the passenger. A plurality of sensors (16a-16i) are associated with the injector. A weighing machine (18) is also associated with the injector (14) for weighing the piece of luggage whilst in the injector (14). The luggage processing (station 10) also comprises a user interface (20) for receiving various inputs for confirming that a passenger has checked-in and to display information to the passenger during processing of the piece of luggage. A controller (28) is associated with the sensors (16a-16i) and weighing machine (18) and the user interface (20). The controller (28) is adapted to accept the piece of luggage if the input received via the passenger's boarding pass or identification card indicate that the passenger has checked-in for the trip, feedback from the sensors (16a-16i) indicates that predetermined criteria are met, and if feedback from the weighing machine (18) indicates that weight of the piece of luggage is within a predetermined limit.

    • An ultrasonic insertion flowmeter (100) is disclosed having a probe (101) which is adapted to be inserted into a duct, the probe having at least first and second ultrasonic transducer means, the probe (101) being adapted to measure the transit time difference of an ultrasonic pulse along a first path and a second path, the difference in transit time for signals along the two paths enabling the flow rate to be measured. Preferably, the probe takes measurements in both the forward and reverse directions along each path, and is adapted to rotate after initial insertion from an insertion position to a measurement position, whereafter the probe (101) may be drawn up against a wall of the duct so that alignment of the probe within the duct is readily achieved.

    • A capacitively coupled magnetic flowmeter is disclosed for measuring flow rate of fluid in a conduit in which the fluid flows, comprising means (10) for generating a magnetic field in the fluid in a direction transverse to the direction of fluid flow, electrode means (8) capacitively coupled to the fluid for measuring the potential difference induced in the fluid by the magnetic field, and electronic means (25) connected to the electrode means (8) to produce a signal proportional to the flow rate of the fluid, in which the electrode means (3, 4) comprises a pair of measurement electrodes (15), located at diametrically-opposed positions in the conduit, each measurement electrode (15) being insulated from the fluid by at least one dielectric portion (16), and a reference electrode (17) corresponding to each measurement electrode (15), each reference electrode being capacitively coupled to the corresponding measurement electrode (15) by at least one dielectric portion (18). Changes in capacitance of the dielectric portion (16) between the measurement electrode (15) and the fluid can therefore be compensated by changes in the capacitance of the dielectric portion (18) between the measurement electrode (15) and the reference electrode (17).
