Abstract: PURPOSE: An apparatus for measuring flow rate of gas is provided to remarkably reduce inspection time for a flowmeter and to save manufacturing cost thereof by simplifying and lightening the flow rate measuring apparatus. CONSTITUTION: A flow rate measuring apparatus includes a body(110) connected to a pipe(66) so as to form a closed space for allowing fluid to be maintained in the pipe(66). The pipe(66) is coupled to the body(110) through an upstream cap(111). A nozzle plate is provided to a downstream end of the body(110). A plurality of nozzle sections are installed on the nozzle plate so as to allow fluid contained in the body(110) to flow into a predetermined fluid path. A branch pipe(130) is coupled to an outlet side of each nozzle section. The branch pipe(130) has a valve for opening/closing a fluid path. A downstream cap(133) is coupled to an end of the branch pipe(130).

Abstract: 누설율 모니터링 장치가 개시된다. 본 발명에 따른 누설율 모니터링 장치는 복수 개의 유로들중 하나의 유로를 선택하는 선택 수단과, 측정 범위에 따라 선택적으로 누설율을 측정하도록 유로별로 서로 다른 유량 측정 범위를 가지는 유량 센서를 구비하는 유량 측정부, 및 상기 유량 측정부로부터 출력된 데이터를 소정의 교정식을 사용하여 교정하는 중앙 처리부를 포함하는 것을 특징으로 한다.
본 발명에 따른 누설율 모니터링 장치는 서로 다른 유로에 그 유로의 용량에 해당하는 복수 개의 유량 측정기를 설치하고 측정 범위에 따라 선택적으로 누설율을 측정하는 것이 가능하므로 누설율의 측정 영역이 넓으며, 2차 교정식을 사용하여 센서로부터 출력된 데이터를 보정하여 결과적인 측정값으로 사용하기 때문에, 센서의 사용 기간이 오래되어 직선성이 떨어진 경우에도 비교적 정확한 결과를 얻을 수 있다. 또한, 본 발명에 따른 누설율 모니터링 장치는 일정 시간 동안의 측정 결과를 메모리에 저장할 수 있고, RS-232C 통신을 통하여 누설율 측정을 위한 각종 메뉴를 제어하고 측정 결과를 컴퓨터로 전송받을 수 있기 때문에 향후 측정 데이터를 인쇄하거나 분석하는데 편리하다.-

Abstract: PURPOSE: A wet gas flow measuring device is provided to easily adjust fluid level, to easily grasp integral value and to improve convenience by converting detected gas flow into flow under standard temperature and air pressure. CONSTITUTION: A device includes a drum(208); a magnetic coupling; an encoder; a level adjusting part; and a conversion/display part. The drum comprises a fixed number of compartments and an axis and has an inlet and an outlet of gas separated from each other and is filled with sealing fluid. The magnetic coupling couples the drum in a chamber(202) and the encoder outside the chamber by magnetism so that an axis of the encoder rotates by rotation of the drum. The encoder is driven by the magnetic coupling as the drum rotates to output pulse proportional to the rotation frequency of the drum. The level adjusting part has a bar(220) inserted by screw to adjust level of the sealing fluid by adjusting volume of the bar sinking under the sealing fluid. The conversion/display part calculates gas flow data based on the pulse to convert into flow under standard temperature and air pressure and display.

Abstract: The present invention relates to a flow meter and a system for measuring the flow rate of a pipe with the flow meter. The flow meter comprises: a first body having multiple total pressure holes; a second body overlapped with the first body and having multiple static pressure holes; and a differential pressure sensor connected to the first and second bodies to calculate the differential pressure between the pressures measured through the total pressure holes and the static pressure holes. In order that the differential pressure is measured as a mean value inside a pipe, the multiple total pressure holes are arranged along the circumferential direction of the first body and are connected by the first body to collect fluid entered through the total pressure holes at one point. Accordingly, the flow rate measuring device can conveniently measure the flow rate with less pressure loss. [Reference numerals] (130) Differential pressure sensor; (20) Flow rate calculator
