摘要： A network of remote sensing node assemblies, a first and second of which each has a sensor element, as well as associated technique and program code for transmitting information collected about a liquid environment. The network provides the capability of sensing the liquid to collect a wide variety of types of information/data about the liquid and any surrounding environments, and transmitting from the originating node assembly to a different node within acoustic transmission range, and then transmitting further to a third node assembly where the information may be processed and communicated to a user, or further transmitted by way of suitable medium, preferably as electromagnetic signals, to a host location for processing into a compilation of data. Each of at least two sensing node assemblies has at least one sensor element adapted for operation while immersed within the liquid, a source of power, and a transducer for receiving acoustic waves/signals transmitted from another node assembly. The transducer is adapted for emitting sensor information collected by one or more sensor element(s) at that node, as well as acting as a pass-through node for information collected at other nodes. A third node assembly of the network is adapted for receiving and processing sensor information acoustically transmitted from other nodes. The third node can have its own processor unit(s) and means for transmitting sensor information to a remote host, whether originating at the third node (if so equipped) or another node assembly

摘要： There is disclosed a method and apparatus for repetitively taking samples of a predetermined quantity of a test gas in a liquid and introducing these samples to a test chamber. Each sample is agitated to release therefrom the test gas. The released gas is then conveyed to a sensor, which monitors the released gas for the presence of a concentration above the threshold level to produce an alarm indicative thereof. The samples of the test gas in a liquid may be repetitively taken from one zone of a plurality at a time until each zone is sampled. After one sample has been tested in the test chamber, it is discharged therefrom and the test chamber is flushed with a sample of the liquid and test gas taken from the next zone of the plurality before introducing the next sample from the next zone.

摘要： There is a method and disclosed apparatus for detecting for the presence within a gaseous atmosphere of a gas of a concentration above a preset level. The detecting apparatus comprises a sensor including a heater/anode element and a collector/cathode element disposed to define a space therebetween through which the gaseous atmosphere flows. An actuable power supply is coupled to the heater/anode element and to the collector/cathode element for applying power thereto, whereby ionization of the gas causes a current flow through the collector/cathode element of a magnitude proportional to the concentration level of the gas in the gaseous atmosphere. An actuable alarm means provides an indication of the presence of the gas above the preset level. Detecting apparatus control operates the detecting apparatus in a monitoring mode, wherein the power supply is actuated and the alarm deactuated to detect and compare the current flow with the preset level. Upon first detecting current which is equal to or exceeds the preset level, the control operates the detecting apparatus in a leak wait mode, wherein the power supply is actuated and the alarm deactuated to initiate the timing of a period while comparing throughout the period detected current flow with the preset level. If the detected current flow remains equal to or greater than the preset level until the period times out, the control operates the detecting apparatus in an alarm mode, wherein the power supply is deactuated and the alarm is actuated.

摘要： There is disclosed apparatus for monitoring the concentration levels of halogen gas in a gaseous atmosphere as confined in an enclosure over a relatively extended period of time. Such monitoring apparatus includes a sensor including first and second electrodes disposed to define a space therebetween through which the gaseous atmosphere flows and a voltage source for applying a voltage between the first and second electrodes whereby an ionization current flows to the first electrode. A control mechanism illustratively in the form of a programmed microcontroller monitors the ionization current collected by the first electrode as the output signal of the sensor, to determine an increase therein as would be indicative of a halogen leak. Upon determining an increase of the sensor output signal above a predetermined difference, the control mechanism removes the energization from the halogen sensor whereby the ionization current is terminated and the life of the sensor extended. The control mechanism further causes an initial reading of the sensor signal to be taken and to be stored, whereby subsequent sensor readings may be compensated by subtracting the stored value therefrom to provide a compensated output indicative of the increased halogen level with respect to the initial background reading thereof. The relatively small halogen sensor output is amplified by a variable gain amplifier, whose gain setting is automatically set over a large range of sensitivities.
