A method for controlling a discrete level FLUID AND SYSTEM (UNIT) involved in its implementation

摘要

1. A method for the control of discrete fluid levels comprising occupancy level sensors with the control points in the vessel, cyclic alternating connection of sensors to a measuring apparatus, measuring the parameters of all sensors from the bottom up or top down at each polling cycle, averaging the measured values ​​over a certain period time, transmission of the information signal on the sensor condition, the connection of adjacent sensors as sensor parameters change when immersed or and attraction of the liquids, the compound sensitive elements together in measuring circuits on printed circuit boards, with which the measuring channel signals are fed to the measuring input of the device, a controller which alternately cyclically connects the outputs of the measuring circuits, and comparing the signal with a threshold value, determines the medium (liquid or gas ) at the control point, characterized in that the series connection is carried neighboring sensitive elements together in the measuring circuit on the circuit board, with koto swarm to the input of the measuring device receives the sum signal, the value of which changes over the predetermined time interval is compared with a threshold value, the signal from the measuring circuit changes abruptly at the transition boundaries of the liquid-gas or gas-liquid interface any sensor element included in the measuring skhemu.2. The system (apparatus), which provides an implementation of method according to claim 1, comprising a block level sensors with sensing elements made in the form of a printed circuit board with holes, which are arranged above the substrate
