    Abstract: A field device detects the presence of terminal leakage between a first terminal and a second terminal in the terminal block area of the field device using a voltage variation ratio that is based on variations in a terminal voltage located across output terminals of a field device and variations in a current regulation voltage located within a current regulation circuit. Preferable, the field device measures an initial voltage variation ratio κ 0 and a subsequent voltage variation ratio κ 0 . Based on the initial voltage variation ratio κ 0 and the subsequent voltage variation ratio κ 0 the terminal leakage existing between the first terminal and the second terminal can be calculated.

    Abstract: The present invention relates to a method and a device for measuring volume flow rates of liquid phase components and gas and determinating their volume concentrations in a multiphase mixture along a pipeline. Measurements are executed with an ultrasonic system which includes a set of local acoustic transducers arranged in the interior of the pipeline. Each pair of an emitter and a receiver of the transducer forms a sampling volume of a medium being under control. Volume concentrations of mixture components are determined by timing of passage of acoustic pulses through the sampling volume of the medium. Volume flow rates of the mixture components are calculated by measuring phase velocities and volume concentrations in two pipeline divisions with different cross-section areas located in series at a distance one from the other in flow direction.

    Abstract: A method for controlling the gas flow within a digital mass flow controller. The method calculates a digitally enhance flow rate signal that more accurately represents an actual flow rate through the digital mass flow controller. The digitally enhanced flow rate is calculated using a sensed flow rate signal output from a flow sensor, a scaled first derivative of the sensed flow rate signal, and a scaled, filtered second derivative of the sensed flow rate signal. A set-point signal is compared to the digitally enhanced flow rate signal to generate a digital error signal. The digital error signal is provided to a digitally realized PI (proportional integral) controller. The PI controller generates a digital control signal which is used to control a valve in the digital mass flow controller.
