    • A system of one or more configurable flowmeters allows an individual, locally or remotely, to selectively activate one or more functions of the flowmeters. The individual is capable of selecting which parameter of the process flow that the flowmeter is to measure, thereby effectively providing latent functions that may be selectively brought on line or shut off. The system may also allow an individual, locally or remotely, to selectively activate one or more latent flowmeters in the system. The system may be a distributed control system (DCS), which receives input signals from conventional meters and devices in the process flow and provides control signals to one or more devices in the flow process. The system may also provide a method of flowmeter selection and billing.

    • Method and device for acoustic flow measurement for measurement of the flow velocity (v) of gases and/or of quantities derived from same. A long-wave sound is transmitted into the measurement pipe (10) and, by means of two sound detectors (14a, 14b) placed at a certain distance (L) from one another in connection with the measurement pipe (10), the sound signals that propagate in the gas flow downstream and/or upstream are detected, the flow velocity (v) of the gas that flows in the measurement pipe (10) being determined by means of correlation of said sound signals.

    • Method and device of acoustic flow measurement for measurement of the flow velocities of gases and/or of quantities that can be derived from same. Long-wave sound is transmitted into a measurement pipe (10). The sound signals passing in the gas flow downstream and upstream are detected by means of two sound detectors (14a, 14b) placed in connection with the measurement pipe (10) at a specified distance (L) from one another, the flow velocity (v) of the gas that flows in the measurement pipe (10) being determined by making use of polarity correlation (15; 151, 152) of said signals. The frequency of the sound that is transmitted into the measurement pipe (10) is scanned between a certain minimum and maximum frequency (fmin...fmax). The measurement signals (fa &cir& _(t), fb &cir& _(t)) arriving from the two sound detectors (14a, 14b) are passed to a narrow-band filter (17a, 17b) or system of filters (17a1, 17a2, 17b1, 17b2). The passband of said filters (17) is scanned synchronously with the frequency scanning of the sound transmission. The duration of the frequency scanning and the width of the passband of said filters (17) are chosen so that, at the moment of the measurement sequence, the measurement signal detected by each sound detector (14a, 14b) has access through its filter (17) substantially without attenuation, as well as so that the interference frequencies substantially different from the mean frequency (f0) of the filters (17) are attenuated significantly.
