A flow conditioner includes a group of flow conditioning units including a first flow conditioning unit and a second flow conditioning unit. The flow conditioner also includes a mixing space for developing a flow. The mixing space is located between the first and second flow conditioning units. One of the first or second flow conditioning units can include one or more of a shaper or a reducer, and the other of the first or second flow conditioning units can include one or more shapers.

A rectifier and a flowmeter, the rectifier including a fairing, wherein a first rectifying section () positioned at the upstream, a reducing section () positioned at the midstream and a second rectifying section () positioned at the downstream, can be arranged in the fairing. The first rectifying section and the second rectifying section are respectively provided with a group of rectifying channels parallel to the flow direction of fluid, and a through-hole () can be formed in the reducing section. The rectifier can provide improved rectification effects.

An ultrasonic flow meter includes a housing for attaching to a fluid pipe. A first piezoelectric element coupled to a transmitter and receiver is configured to emit ultrasonic waves in an axial direction perpendicular to a horizontal plane defined by the piezoelectric element. A lens combination is in a lower housing portion positioned radially outside the first piezoelectric element including a refocusing lens that is ring-shaped configured for redirecting received radial ultrasonic waves to travel in an axial direction perpendicular to the horizontal plane and has a thickness profile configured to act as a matching layer for reducing multiple reflections within the lower housing portion. A second lens that is disc-shaped below the refocusing lens is configured for redirecting the radial ultrasonic waves to travel in the axial direction.

A Static Random Access Memory (SRAM) array power supply circuit is presented. The circuit comprises an SRAM test unit having a substantially same structure as a basic SRAM unit in the SRAM array; a switch device connected to a power source, the SRAM test unit, and the SRAM array; and a switch control circuit connected to the SRAM test unit and the switch device. When a test voltage in the SRAM test unit is lower than a threshold voltage, the switch device is closed so that the power source begins to charge the SRAM array and the SRAM test unit. The SRAM test unit provides an early warning for the SRAM array, allowing the latter to be charged upon fulfillment of a condition (e.g., charge is low). Compared to conventional circuits, this circuit provides an output voltage that is more stable and less susceptible to the changes in external conditions such as temperature or pressure.
