  • Patent number: 7328611
    Abstract: An Arrangement for the measurement of a level of a medium in a container the arrangement allows for removal of the microwave level measurement device, without opening the container, which allows use of standard connectors. The arrangement comprises: a mounting section surrounding an opening of the container; a tubular adapter comprising a first standard connector located on a first end of the adapter and a second standard connector located on a second end of the adapter, which is mounted on the mounting section of the container by the first standard connector; an isolation window transparent for microwaves seating a passageway through the adapter having an outer rim, which is clamped between the mounting section and the first standard connector; and a microwave level measurement device, comprising a standard process connector to be mounted on the second connector of the adapter.

  • Patent number: 7194363
    Abstract: 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.

  • Patent number: 7044001
    Abstract: 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
