Applications
The fields of application for MASS-VIEW® mass flow meters are diverse:
Burner Control (furnace construction)
Welding (welding gas monitoring)
Leak measurements (quality, environment)
Coating (equipment construction)
Regulation of gaseous atmospheres (biotechnology)
Measurements of gas consumption (hospitals)
Test equipment (production maintenance)
Local preparation of a gas mixture
Flow rate monitoring (laboratories)
Cutting (steel sheets)
Cost centre billing
Analytical equipment
Measurement / control system
Flow range
20 mln/min .. 200 mln/min (sccm)
Mass flow units ln/min and SLM refer to normal operating conditions, i.e. 0°C (32°F) and 1013 mbar (14.7 psi)
Accuracy
± 2% RD for flow > 50% of max. capacity
± (1% RD + 0.5% FS) on lower flows
Technical specifications are based on Air at maximum FS
Repeatability
< 0.2% FS typical
Pressure coefficient
0.2% / bar typical at Air
Standard calibration gas
Hydrogen H2
Rangeability
up to 1:20
