Abstract: A lambda probe (1) is used with the measuring apparatus for monitoring residual oxygen in an exhaust gas, in which a measuring point for oxygen in a sensor (2) is connected via a diffusion gap (22) with a reaction chamber (24). During operation of the probe the reaction chamber drives a stream of oxygen IO2 along the diffusion gap by means of a controllably adjustable oxygen partial pressure pi. By means of an electro-chemical, oxygen ion pump driven by an electrical pump current Ip, an oxygen partial pressure pi predetermined as a desired value is set in the reaction chamber. In this arrangement the pump current, the strength of which is proportional to the strength of the stream of oxygen driven along the diffusion gap, can be used as a measurement parameter for the partial pressure pm of the residual oxygen in the exhaust gas or its concentration. The residual oxygen can be monitored during a normal operating phase, the phase N. The lambda probe can be operated for test purposes, at times, particularly intermittently in a phase H or a phase L. In these operating phases H and L the oxygen partial pressure pi in the reaction chamber (24) adopts a largely minimum value or a largely maximum value. By means of changing between the named operating phases, by registering the pump current Ip and by comparing the registered pump currents Ip with empirical values, conclusions with regard to the ability of the probe to function (1) can be derived, so that if necessary, in the case of a lacking or faulty ability to function, measures can be introduced to remedy the deficiencies or to exchange the sensor (2).

Abstract: An A/F sensor outputs a linear air-fuel ratio detection signal proportional to the oxygen concentration in an exhaust gas from an engine upon application of a voltage. A computer controls the applied-voltage in a stoichiometric control region, a lean burn control region, an atmosphere detection region and a rich control region to have a fixed value such that the change rate of the applied-voltage is reduced to be less than that in other regions. In addition, when changing the voltage applied to the A/F sensor, the computer variably sets the voltage change speed sequentially. Thus, the influence of the capacitive characteristic of the A/F sensor is eliminated.

Abstract: The instant invention relates to an apparatus for measuring a powder mass flow in a powder/gas mixture during the conveyance thereof through a feed pipe, the apparatus comprising a velocity measuring device for the powder/gas mixture, a mass measuring device for the powder mass per volume unit, and a calculating device to calculate the powder mass flow based on the velocity measured, the powder mass per volume unit measured, and the dimensions of the feed pipe. The mass measuring device comprises a microwave resonator and means for sensing the resonant frequency and/or the microwave amplitude of the microwave resonator. The microwave resonator is embodied by a coil which is applied on the outside of the feed pipe. The invention likewise proposes a method of measuring the powder mass flow in a feed pipe wherein measuring of the powder mass per volume unit involves establishing a reference resonance of a known powder mass flow, adjusting two measuring frequencies at either side of the reference resonance, measuring the resonator voltage at the adjusted measuring frequencies and forming the difference thereof for a powder mass flow to be measured, and determining the displacement of the resonant frequency based on the voltage differential.

Abstract: A system for evaluating multiphase flow of a fluid downhole in a borehole. Dielectric permittivity electrodes generate a capacitance output signal through the fluid, and conductivity electrodes generate a conductivity output signal through the fluid. The electrodes are powered with an AC generator operating at the same or different frequencies. The capacitance and conductivity output signals can be alternately generated by operating a controller, and such signals can be combined with a multiplexer engaged with the controller. The signal can be processed downhole or can be transmitted to a receiver positioned at the well surface for processing and interpretation of the multiphase data.

Abstract: The flowmeter comprising a first flow passage with a fixed cross section geometry and a second flow passage with a variable cross section geometry measures the volume and mass rates of fluid flow through the flowmeter as well as the density of the fluid. The variable cross section geometry of the second flow passage varies as a function of the dynamic pressure of the fluid flow and the difference in the volume or mass rate of the fluid flow between the two flow passages varies as a function of the variable cross section geometry of the second flow passasge. The volume or mass rates of the fluid flow through the two flow passages are measured and the dynamic pressure of the fluid flow is determined therefrom, whereupon the volume and mass flow rates of the fluid flow and the density of the fluid are determined from the data on the volume flow and the dynamic pressure, or from the data on the mass flow and the dynamic pressure.
