    • An apparatus for determining the concentration of solids or for measuring the interface between a liquid and settled solids in a settling vessel, comprising: (a) electrical conductivity or resistivity measuring means adapted to monitor electrical conductivity or resistivity within a liquid in a vessel; and (b) monitoring means which is capable of recording electrical conductivity or resistance levels within the vessel and which is capable of determining the concentration of solids from the electrical conductivity or resistivity results. Where the apparatus consists of a conductivity sensor (1) which is in electrical communication with and suspended by a cable (2) from a winch (3). The winch is controlled by the operation of a motor (4) which is controlled by a monitoring means (5). The conductivity sensor signals are transferred from the cable (2) by sliprings (6) to a conductivity meter (7). The conductivity data is then passed from the conductivity meter to the monitoring means (5) which measures positional data from a shaft encoder (8) and controls the position of the conductivity sensor by instructing the winch (3) to raise, lower or hold the sensor in any position inside the settlement vessel. The monitoring means is adapted to continuously examine conductivity data from the sensor.
    • 一种用于确定固体浓度或用于测量沉降容器中的液体和沉降固体之间的界面的装置,包括:(a)适于监测容器内的液体内的导电性或电阻率的导电性或电阻率测量装置; 和(b)能够在容器内记录电导率或电阻值并且能够根据导电性或电阻率结果确定固体浓度的监测装置。 该设备由电导率传感器(1)构成,电导率传感器(1)与绞盘(3)电连通并由电缆(2)悬挂。 绞盘由通过监视装置(5)控制的马达(4)的操作来控制。 电导率传感器信号通过滑环(6)从电缆(2)传送到电导率计(7)。 然后,电导率数据从电导仪传递到测量来自轴编码器(8)的位置数据的监视装置(5),并通过指示绞盘(3)升高,降低或保持电导率传感器的位置来控制电导率传感器的位置 传感器在沉降容器内的任何位置。 监测装置适于连续检查传感器的电导率数据。
