MASS-STREAM THERMAL MASS FLOW METER FOR GASES
MASS-STREAM mass flow meters for gases are based on the thermal through-flow measurement principle.
Covering a wide measurement range, from 0.5…50 ln/min up to 10…1000 ln/min Air equivalent. Each Mass Flow Meter is equipped with exciting features, like our multi-functional on-board display for indicating actual flow, totalized flow, and alarms.
All 4 models, have 6 pre-installed gases: Air, N2, O2, Ar, CH4, CO2; analog 4-20mA output signals and Digital RS-232 communication. With Bronkhorst’s FLUIDAT Onboard it is possible to select other gases or mixtures via our free software Bronkhorst FlowSuite.
