This paper describes a system for measurement and control of a gas flow. In order to measure the flux of gas and control a vavle according to flux, this system was developed. This system is implemented on the personal computer and its environment is developed tool called TMS. This system includes a main program and Tele-Metering Unit for transmitting correcting flow value based on temperature and pressure in flow computer and AD converter for transmitting instantaneous flow rate, temperature and pressure as interface part of personal computer. This system was made by Visual C++ program. Using this system, inspected data for the recognition of transmitting flow value are generated on the screen, file and printer. The activity, reliability of this system was verified on Daegu-Citygas that aids the system for the acquisition of inspected data by realtime application.

The real-time modeling system, named AirWatch System, has been developed to evaluate the environmental impact from a large source. It consists of stack TMS (TeleMetering System) that measures the emission data from the source, AWS (Automatic Weather Station) that monitors the weather data and computer system with the dispersion modeling software. The modeling theories used in the system are Gaussian plume and puff models. The Gaussian plume model is used for the dispersion in the simple terrain with a point meteorological data while the puff model is for the dispersion in complex terrain with three dimensional wind fields. The AirWatch System predicts the impact of the emitted pollutants from the large source on the near-by environment on the real -time base and the alarm is issued to control the emission rate if the calculated concentrations exceed the modeling significance level.

오염물질을 실시간으로 측정해 배출사고를 예방할 수 있는 원격측정시스템(TMS : Tele-metering System)이 폐수 배출사업장에도 도입된다. 환경부는 오는 2007년까지 1~3종 배출업소와 하$\cdot$폐수종말처리시설 등 2,443개 폐수배출사업장에 오염물질 측정기기를 부착해 환경관리공단에 설치될 관제센터에 연결한다고 밝혔다. 이를 통해 한해 동안 배출되는 폐수의 86.2%가 실시간으로 관리될 전망이다. 배출사업장은 폐수의 특성에 따라 유량계, 자동시료채취기, 생물학적산소요구량(BOD)$\cdot$화학적산소요구량(COD),$\cdot$총질소(T-N)$\cdot$총인(T-P)$\cdot$부유물질(SS)측정기기 등을 최소 1종부터 최대 7종까지 설치해야 한다. 그러나 자동측정이 어려운 총대장균군수$\cdot$색도$\cdot$노르말헥산 등은 수동측정법을 유지키로 했다. 업체별로 최대 1억7천~2억원까지 예상되는 설치비는 사업자의 부담을 덜기 위해 융자 지원할 계획이다. 이에 본지에서는 그 내용을 간략히 파악해 보고자 한다.
