摘要： A liquid level gauge for use on a vehicle indicates a liquid level in a start-up and in a running state in accordance with requirements designated by a user of the vehicle, the level being indicated with little or no time lag. Data detected in analog form by a fuel sensor is converted to digital signals by a sensor value reader. An indicator driver receives time signals from a timer and speed signals from a vehicle speed sensor and, in a suitably timed manner reflecting the vehicle speed, calculates fuel level data to be indicated based on the digital signals. The fuel level data thus calculated is indicated on a fuel level indicator. The fuel level data may be updated at intervals of one second if vehicle speed is less than 4 km/h and at intervals of 15 seconds if vehicle speed is at least 4 km/h. The indicator driver calculates the fuel level data using the digital signals unmodified or an average of digital signals obtained using a rapid averaging process, whereby fuel level is indicated with little or no time lag.

摘要： A sensor arrangement determines a condition and level of a liquid in a container. A first sensor has first electrodes forming a first measuring chamber communicating with the liquid and supplies a signal for determining an impedance of the first sensor and a condition of the liquid in the container. A second sensor has second electrodes forming a second measuring chamber communicating with the liquid via the first measuring chamber and supplies a signal for determining an impedance of the second sensor and a level of the liquid in the container. Electronic devices are coupled to the first and second sensors, and determine the impedance of the first and second sensors and the condition and level of the liquid in the container.

摘要： A method for measuring level with a plurality of capacitive sensors arranged next to each other along a filling section. The method steps are: subjecting a sensor to a measuring signal and subjecting an adjacent sensor to a phase-displaced measuring signal. Then the resulting signals on the sensors are measured. Next the phase displacement between the resulting signals is determined. Then the level is established in accordance with the phase displacement.

摘要： A capacitive sensor array is adapted to be disposed in a reservoir containing fluid or material along an axis of measurement of the fluid or material to determine the level of fluid or material contained within the reservoir. The sensor array includes a plurality of reference electrodes, wherein the capacitance of each of the electrodes varies in accordance both with the extent of the array's immersion in the fluid or material and the dielectric constant of the fluid or material. The plurality of reference electrodes preferably includes a lower electrode adapted to be immersed within the fluid or material in the reservoir and whose capacitance provides an estimate of the dielectric constant of the fluid or material contained within the reservoir. The reference electrodes also include an upper electrode adapted to be positioned above the fluid or material level that provides an estimate of the dielectric constant above the level of the fluid or material in the reservoir, and a middle electrode whose capacitance varies from a calibrated initial value to a value that is dependent on the level of and the dielectric constant of the fluid or material contained within the reservoir as determined from the capacitance of the lower electrode.

摘要： A sensor for detecting levels of fluids and particulate matter is based on differences in dielectric constants of the various materials. The difference is reflected in different capacitance across electrodes immersed to different depths in such materials. A square-wave clock pulse is input into circuit composed of the capacitance and a resister in series. The output voltage is fed into a logic unit (such as exclusive-OR), which converts the exponential decay of the voltage into a pulse of uniform height with duration proportional to the time constant (proportional to the capacitance) of the exponential decay. The pulse is optionally fed through a low-pass filter to give a signal proportional to the duration.

摘要： The subject matter of the present invention is the optimization of a capacitive liquid level sensor which is suitable, in particular, for determining the location of a boundary layer 12 between water 10 and oil 11 in a separator tank. The known sensor principle is based on measuring the environmentally dependent capacitance between neighboring electrodes 13, 4; 4, 5; 5, 6 of a rod-shaped probe 1. According to the invention, the probe 1 is designed such that large ionic double-layer capacitors occur on the electrodes 4, 5, 6, 13 in the more conductive medium 10, and small capacitors occur between electrodes 4, 5, 6, 13 in the insulating medium 11. For this purpose, the electrode height h is selected to be large, the ratio of the electrode height h to the electrode spacing a is preferably selected to be in the range of 1

摘要： The object of the invention is the detection of a given threshold (optionally zero) for filling, with an electrically conductive product, a reservoir made of electrically insulating material having a storage cavity connected to an outlet channel. An excitation signal is applied to the cavity, in periodic square waves, and a measurement signal is taken off, one characteristic of which varies substantially with the quantity of product contained in the cavity reaches the filling threshold. From this characteristic, by comparison with a reference threshold, a binary signal C,C′ is derived, which is filtered digitally whilst multiplying it (convolution product) by a signal which is identical to it, but with a delay equal to a multiple, at least equal to one, of the period of the square waves.
