摘要： An electricity meter comprising an electrically-controlled electromechanical switch is disclosed. The electromechanical switch comprises a rotary actuator comprising a generally-cylindrical permanent magnet rotor having a central axis, a stator comprising a closed stator core and first and second opposite stator poles inwardly-projecting from the closed stator core towards the rotor and first and second coils wound around the first and second stator poles respectively. The electromechanical switch comprises a switch comprising at least one pair of first and second contacts wherein the first contact is movable. The electromechanical switch comprises mechanical linkage between the rotary actuator and the movable contact(s) configured such that rotation of the rotor from a first angular position to a second angular position causes the switch to be opened, and rotation from the second angular position to the first angular position causes the switch to be closed.

摘要： An electricity meter (17) is described which includes a conductor (19) for transferring energy from a supply (20) to a load (21). The electricity meter (17) also includes a multi-layer printed circuit board (18) mechanically attached to the conductor (19). The multi-layer printed circuit board (18) includes two or more insulating layers (26, 27, 33, 34). The two or more insulating layers (26, 27, 33, 34) include a first insulating layer (26, 27) having an attachment surface (28) facing the conductor (19). The multi-layer printed circuit board (18) also includes a first conductive layer (29) including a first planar sensor coil (30). The first insulating layer (26, 27) is between the first conductive layer (29) and the conductor (19). The multi-layer printed circuit board (18) also includes a second conductive layer (31) including a second planar sensor coil (32). The multi-layer printed circuit board (18) also includes a second insulating layer (26, 33) between the first (29) and second (31) conductive layers. The first planar sensor coil (30) and the second planar sensor coil (32) are electrically connected to one another by a buried via (40), or the first planar sensor coil (30) and the second planar sensor coil (32) are electrically connected to one another by a blind via (38) extending inwards from a back surface (35) of the multi-layer printed circuit board (18), the back surface (35) being opposed to the attachment surface (28).

摘要： An electromagnetic flow sensor for an electromagnetic flow meter (201) is disclosed. The sensor comprises a body (204) or frame, a flow passage (252) through the body or frame, a part of a magnetic circuit (248, 295) supported by the body or frame for applying a magnetic field across the flow passage, and at least first and second electrodes (298) supported by the body or frame, the at least first and second electrodes arranged to sense a voltage in response to a conductive fluid flowing through the flow passage. At least a portion of the body supporting the magnetic circuit part and the at least first and second electrodes is configured to be insertable into a flow tube (206) through a single aperture in the flow tube.

摘要： A method for an ultrasonic time-of-flight flow meter (1) includes driving an ultrasonic transducer (2, 3) using a first waveform (V1(t)) for a first duration (Δt1), the first waveform (V1(t)) configured to cause oscillation (21) of the ultrasonic transducer (2, 3). The method also includes driving the ultrasonic transducer (2, 3) using a second waveform (V2(t)) for a second duration (Δt2). There is a discontinuity between the first waveform (V1(t)) and the second waveform (V2(t)). The second waveform (V2(t)) and the second duration (Δt2) are configured to maintain a voltage (VT(t)) across the ultrasonic transducer (2, 3) within a predetermined range (VH, VL).
