HIGH PRESSURE / High ΔP
Digital GAS Mass Flow Meters & Controllers

General

Bronkhorst® 의 EL-FLOW® and IN-FLOW Series 열 질량 유량계 / 컨트롤러 는 적용 장비의 고압 (차압)에 대하여 특별한 기능을 제공합니다. 특허를 받은 PN400/PN700 제어벨브는 일체 또는 개별적으로 설치 가능하며, 가스의 흐름을 측정 및 컨트롤 할 수 있습니다. 유량의 범위는 다음과 같습니다 :

질량 유량계                 0,2...10 mln/min 부터 10...500 m3n/h 까지
질량 유량 컨트롤러      0,2...10 mln/min 부터  2...100 ln/min 까지

"Multibus" Digital Mass Flow Meters/Controllers

EL-FLOW Select series 모든 모델은 디지털 PC-보드를 갖추고 있어 자가진단, 경보, 카운터, 디지털 통신(RS-232) 및 원격 제어기능 등이 있습니다. Bronkhorst® 디지털 기기는 멀티버스 컨셉으로 높은 유연성을 가지고 있습니다. 옵션에서 해당 인터페이스 보드를 장착하여 쉽게 DeviceNet™, PROFIBUS DP, Modbus, EtherCAT® 또는 FLOW-BUS protocol에 대응 할 수 있습니다(MBC3 pcb 필수).  Digital "multibus" communication에대한 자세한 정보.
