Abstract:
1. A sonic- or ultrasonic flowmeter which replaces a differential pressure flowmeter, comprising: a pipe segment connected to a first pipe and to a second pipe, each having a diameter, which complies with an industry standard for pipe diameters used in differential pressure flow measurement, a length, which is equal to a standard length for a flow restricting element of a differential pressure flowmeter, and a diameter, which is equal to a standard for pipe diameters used in differential pressure flow measurement; a first standard connector located on a first end of said pipe segment and a second standard connector located on a second end of said pipe segment; a primary flow sensor, comprising at least one sonic- or ultrasonic transducer for the transmission and/or reception of sonic- or ultrasonic signals across said pipe segment, said at least one sonic- or ultrasonic transducer being mounted on said pipe segment; sensor electronics connected to said primary flow sensor for providing the measurement signal representing a flow of a fluid through said pipe segment, based on the sonic- or ultrasonic signals received by said sonic- or ultrasonic transducers; a housing for said sensor electronics; and a mounting section located on an outside wall of said housing for mounting said housing apart from said pipe segment, said mounting section comprising two pairs of threaded bores, wherein: said threaded bores form a rectangle and their position is equal to a position of threaded bores in the normal oval flanges of differential pressure transducers.
