A method and system for determining a time-of-flight in an integrated flow meter, can include a housing including an inlet port and an outlet port, and a group of flow tubes connected in parallel to each other. Each flow tube among the group of flow tubes can include two or more transducers that can measure upstream and downstream time-of-flight. Each flow tube can further include one or more outlets connected to the outlet port of the housing via an outlet channel. A controller can be connected electronically to the transducers, wherein the controller is operable to measure the time-of-flight in a flow tube for a predetermined time using the transducers, toggle between the transducers of each flow tube to measure the remaining flow tubes within a predetermined time and determine the overall flow rate of the group of flow tubes in the integrated flow meter.

An electrical circuit and a method of operating the electrical circuit can include a group of transistors including one or more of a first transistor and a second transistor, wherein the first transistor is electronically connected to an input and an output of the electrical circuit, and the second transistor is electronically connected to the first transistor and the output. The electrical circuit can also include a group of resistors including a first base resistor and a second base resistor, wherein the first base resistor is electronically connected to a voltage supply, the first transistor, the second base resistor and one or more diodes. The electrical circuit may also include one or more capacitors electronically connected to the input, the first transistor, the second transistor, and the diode(s) and the output, such that an output voltage at the output is approximately double the supply voltage of the electrical circuit.

Methods and systems for flow measurement can involve calculating an absolute-time-of-flight with respect to a flow of a fluid in a flow channel by reflected signals, reflected and unreflected signals, or a pulse train, determining a delta-time-of-flight with a cross correlation of two signals with respect to the flow of the fluid in the flow channel, and calculating the flow rate of the flow of the fluid in the flow channel based on the absolute-time-of-flight and the cross correlation of the delta-time-of-flight.

A method and system for measuring a time of flight can involve correlating a signal comprising a reflected signal from a first transducer to a second transducer, or a subsequent reflected signal at the first transducer or the second transducer, with a previously received signal to produce a correlation for a measurement of a time of flight. The signal(s) can include one or more of a pulse train, acoustic sound; ultrasonic sound; or light, and the previously received signal can be a signal that has been reflected one or more times.

An apparatus for energy and data transfer, can include a first inductor and a second inductor, wherein the first inductor can be magnetically coupled to the second inductor, and a gap configured between the first inductor and second inductor, wherein the first inductor and the second inductor can transfer energy and data between a white meter and an electronic index. The white meter may be implemented as a flow meter. The electronic index can include an electronic display unit that can be attached to the white meter. The electronic display can include one or more of a display unit, a communications unit, or a combination of a display unit and the communications unit.
