높은 정확도, 시스템 영향을 최소화한 다변량 유량 측정
압력 손실이 낮은 “Whisper” 시리즈 Mass Flow Meter는 시스템 충격을 최소화하여 대기압 근처 또는 시스템 압력이 거의 없을 때 유량 측정이 가능합니다.
광범위한 사용 유량 범위 및 다양한 가스를 위한 캘리브레이션 기능은 이 MFM을 오랫동안 작동 상태로 유지합니다.
특징
» 빠른 응답속도 (<10ms)
» Warm-up 타임 불필요, 1초 내에 측정 준비 가능
» 컴퓨터 또는 PLC와 함께 사용 가능 (컴퓨터 또는 PLC 없이 단독 유닛으로도 사용 가능)
» 모든 유량 데이터를 하나의 스크린에서 확인 가능 (Flow, Pressure, Temperature)
» 디지털 및 아날로그 출력
