Abstract: A measuring arrangement for determining at least one measured quantity with a sensor device and a transmitter device that has a control device, a switch device and a signal output setting device. The control device is connected to the signal output setting device in the case in which the switch device is in the first state. The signal output setting device generates a fault signal as an output signal when the switch device is in the second state and/or that the signal output setting device is free of a connection to the control device. The sensor device keeps the switch device in the first state when the sensor device is supplied with energy above a definable minimum value. The control device reduces the power supply of the sensor device to a definable boundary value when it recognizes the presence of a fault state.

Abstract: A process variable transmitter, implemented in a dual PLL structure, includes a first PLL having a first bandwidth producing a first output signal, and a second PLL having a second bandwidth narrower than the first bandwidth of the first PLL. The first and second PLLs are operable to lock into a frequency of an input signal and produce first and second output signals, respectively. The second PLL is operable to lock into the frequency of the input signal with greater accuracy and greater immunity to noise than the first PLL. A switch is operable to switch an output signal of the process variable transmitter between the first output signal and the second output signal.

Abstract: A vortex flow meter includes a measuring tube in which a fluid is carried, a vortex generator provided in the measuring tube for developing a Karman vortex in the fluid, a magnetic field generator generating a magnetic field across the measuring tube downstream of the vortex generator, a pair of electromotive force measuring electrodes provided downstream of the vortex generator for measuring an electromotive force generated by the Karman vortex passing across the magnetic field, a pair of reference electrodes provided at locations upstream and downstream of the electromotive force measuring electrodes, respectively, for measuring a potential at each location, and a detector circuit electrically connected to the electromotive force measuring electrodes and the reference electrodes for calculating the flow of the fluid from the electromotive force and the potential measured by the reference electrodes. The flow is calculated by subtracting the potential difference of the reference potential measuring electrodes from the electromotive force measured by the electromotive force measuring electrodes. This allows the flow meter to have an increased measuring range, meet a wide range of flow conditions, have a simple construction, and have measurement accuracy.

Abstract: A vortex mass flowmeter includes a body for placement in a flow path of a fluid and four capacitive sensors. The body has a sleeve and a rod positioned within a chamber in the sleeve. Two of the capacitive sensors are mounted to sense lateral deflection of the sleeve relative to the rod and two of the capacitive sensors are mounted to sense axial deflection of the sleeve relative to the rod, thereby providing frequency signals related to shedding and drag, respectively. The shedding signal is dependent on the flow velocity, and the drag signal is dependent on the flow velocity and the fluid density.
