A flowmeter suitable for replacement of differential pressure flowmeters comprising: a primary flow sensor, sensor electronics for proving a measurement signal; a signal processing unit for determining the flow, which can be set to produce a signal proportional to the flowrate or the square of the flowrate; and an output signal generator for generating an output signal proportional to the signal of the signal processing unit.

Flowmeter

A low power ultrasonic flowmeter to be powered by a two wire power supply loop is described, comprising: an ultrasonic flow sensor, a signal processing unit for determining a measurement result based on measurements performed by the ultrasonic flow sensor, an input/output unit to be connected to the two wire loop, for controlling a current of the power supplied to represent the measurement result, for receiving power from the power supply loop, and a power management system, for an energy efficient distribution of the power supplied to the flowmeter via the input/output unit, comprising storage means for storing energy during times of low power consumption and resupplying the stored energy during times of high power consumption.

Ultrasonic flowmeter

A sonic- or ultrasonic flowmeter, suitable for replacement of differential pressure flowmeters, comprising: a pipe segment, to be connected to a first and a second pipe, each having a diameter, which complies to an industry standard for pipe diameters used in differential pressure flow measurement, having a length (L), which is equal to a standard length for a flow restricting element of a differential pressure flowmeter, having a diameter (D), which is equal to a standard for pipe diameters used in differential pressure flow measurement, comprising a first standard connector located on a first end of the pipe segment, and a second standard connector located on a second end of the pipe segment, a primary flow sensor, comprising at least one sonic- or ultrasonic transducer for transmission and/or reception of sonic- or ultrasonic signals through the pipe segment, mounted on the pipe segment, and a sensor electronic for providing a measurement signal representing a flow of fluid through the pipe segment, based on signals received by the sonic- or ultrasonic transducers.
