A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor is positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

Disclosed in the present invention is a system and method for supplying acetylene to an apparatus using acetylene, the system having at least one acetylene storage apparatus and an acetylene content analysis apparatus. The system and method disclosed in the present invention can utilize the capacity of an acetylene cylinder to a higher degree; before the solvent impurity concentration in acetylene gas reaches a level where it is no longer suitable, a more accurate understanding of the usable acetylene amount in the acetylene storage apparatus can be gained through detection, thereby reducing the number of times that the acetylene storage apparatus is refilled and replaced, and lowering the user's total costs.

An optimized, energy-sensitive system and method for fulfilling various data needs of gas utilities. In particular, the disclosure relates to optimized methods for discovering and reacting to an alarm. In one aspect, when an alarm is triggered a telemetry unit automatically alters its operating mode to begin transmitting live pressure reads every minute instead of every hour, as typically performed. This variance in operation eliminates the need for a user to monitor a pipeline system for an incoming alarm and manually request data by initiating a live communication session.

Herein pipeline pressure, temperature and NGL constituents are manipulated for the transportation and optional storage in a pipeline system of natural gas mixtures or rich mixtures for delivery of chilled Products for downstream applications. Pressure reduction from a last compression section delivers internally chilled Products for reduced capital and operating costs. A high lift compressor station before the pipeline terminus provides pressure differential for Joule-Thompson chilling of the pipeline contents. The chilling step can be retrofitted to existing pipeline systems, and the chilling steep can include a turbo expander or the like for recovery of pipeline pressure energy for power generation. For like throughout, with this higher pressure operation, the effects of enhanced NGL content results in a reduction in diameter of the pipeline by at least one standard size. Substantial overall reduction in energy consumption and associated CO2 emissions is thereby achieved through integrated pipeline/processing applications.

The embodiments of present disclosure provide a method for processing abnormality of a smart gas pipeline network implemented based on a smart gas safety management platform of a safety management Internet of Things (IoT) system for the smart gas pipeline network. The method may include: obtaining detection information of a gas pipeline in a target area; determining an abnormal pipeline in the target area based on the detection information; and determining an abnormality handling scheme based on the detection information corresponding to the abnormal pipeline.

Improved systems and techniques are disclosed for controlling the security states of anti theft security systems such as product display assemblies using security fobs. The tasks relating to fob authentication are offloaded to a computer system, and these authentications can be based on identifiers for the different security fobs. The computer system can maintain a list of identifiers for authorized security fobs that is easily updated when new security fobs are added to or existing security fobs are de-authorized from the system.
