摘要： An automatic hysteresis compensated method of level measuring a liquid in a tank includes providing an electromechanical liquid level gauge including a controller with a processor, a displacer on a wire from a measuring drum with a motor, where the processor controls a movement of the motor and executes a level gauging algorithm. A measured force displacer position (FS) profile is provided including a move-down FS curve determining Fd, Sd corresponding to a displacer center when moving down and a move-up FS curve to determine Fu, Su corresponding the displacer center when moving up. The algorithm provided a time derivative of F is essentially zero, initiates performing a down/up dip of the displacer moving the displacer down/up to below/above the liquid level, then moving the displacer up/down passing Su/Sd, then moving the displacer to return to Sd/Su, and determining the current liquid level from Fd/Fu upon the return to Sd/Su.

摘要： Fill level monitoring relates to a method for controlling the fill level of a collecting vessel, wherein the collecting vessel could be filled with a dielectric medium. A fill level is monitored by a monitoring circuit with a measuring capacitor, the capacity of which changes steadily in correlation with the fill level, at least beyond a fill level range of the collecting vessel. The method includes: determining a capacity of the measuring capacitor; determining the quality of the measuring capacitor; determining a permittivity of the dielectric medium on the basis of the quality of the measuring capacitor; determining a fill level of the collecting vessel on the basis of the determined capacity of the measuring capacitor and the permittivity of the dielectric medium; and fill level-dependent drainage of the dielectric medium from the collecting vessel.

摘要： The amount of processing liquid consumed from the processing liquid in the tank is calculated based on the history of opening and closing events of one or more of the valves, and that the anomaly detection controller of the substrate processing apparatus generates a level sensor failure alarm if the calculated amount of consumed processing liquid has increased beyond a state transition liquid consumption amount and yet the level sensor has not switched from the first state to the second state. The substrate processing apparatus and the level sensor are designed so that the level sensor switches from the first state to the second state when the calculated amount of consumed processing liquid has increased beyond the state transition liquid consumption amount.

摘要： A continuous measurement of the level of contents in a container is effected by a level measuring device functioning in accordance with the transit time principle by means of waves transmitted from a position located above the highest possible contents level onto the surface of the material in the container. A measuring circuit determines the contents level from the transit time of the useful echo reflected from the material surface. In addition, one or more limit sensors are located at the container, each of which furnishes a signal indicating whether the contents level is above or below a level to be monitored by the limit sensor and which is situated between the minimum and maximum contents levels of the container. The measuring circuit receives the output signals of all limit sensors and uses these output signals to check and eventually to correct the contents level measured value determined by the level measuring device. In particular, the measuring result furnished by the level measuring device can be compared with an exact contents level value every time the contents level reaches the level monitored by a limit sensor whereby the level indication of the limit sensor changes its status. In certain cases, a single limit sensor is sufficient for this purpose, which monitors a contents level which is regularly exceeded or undershot in the normal use of the container.
