Abstract: 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.

Abstract: 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.

Abstract: A static gas flowmeter for sensing a flow of gas includes an outer housing, a flow tube coupled to an outlet or an inlet, ≥1 sensor positioned for sensing gas flowing through the flow tube, and a controller including a memory including a flow calibration and flow measurement algorithm coupled to a sensor receiving a sensing signal. An integrated gas valve is connected to the inlet or outlet and/or there is an additional external valve positioned outside the housing coupled to the inlet to provide the gas flowmeter at least two state operation. Using the valve(s), the flow calibration algorithm triggers a zero-flow condition, then obtains a measured gas flow, and from the measured gas flow a flow offset is determined. If the flow offset is outside a predetermined limit, in-line calibrating is performed by adding the flow offset reflected as a correction factor to the flow measurement algorithm.

CPC classification number: G01F1/662

Abstract: 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.
