MASS-VIEW Mass Flow Regulator with Display for Hydrogen ( lowest flow)
The MASS-VIEW®series operate on the principle of direct thermal mass flow measurement. A major advantage of using this type of sensor is that the instruments measure direct mass flow, without the need for temperature and pressure correction.
Virtually independent of pressure and temperature variations
Low pressure drop
Wide flow ranges
Alarm and counter functions (2 alarm contacts)
Analog (0..5 Vdc) and digital communication (Modbus-RTU, RS-232 interface)
Configurable password protection
3 selectable ranges
High resolution needle valve
Free software tools
The fields of application for MASS-VIEW(r) are diverse:
Measurements of gas consumption
Local preparation of a gas mixture
Flow rate monitoring (laboratories)
Cost centre billing
