Thermal mass flow-meter for harsh environment
max. 11 000 m³n/h, IP65, ATEX Zone-2 | IN-FLOW Bronkhorst

IN-FLOW Series Mass Flow Meters/Controllers are thermal mass flow meters of modular construction with a 'industrial style' pc-board housing. Control valves can either be integrally or separately mounted, to measure and control gas flows from:

lowest range 0,2 ... 10 mln/min
up to highest range 220 ... 11000 m3n/h

The control valve design distinguishes itself from competitive designs in its truly modular construction and it can be field replaced or changed by the user without any adjustment. The standard valve is normally closed and is available up to Kv-values of 6.0.
Normally opened valves can also be supplied. Patented constructions enable us to handle high flows and/or pressures at differential pressures up to 700 bar in the IN-FLOW program, which is unique.

Features

- High accuracy (typical 0,8% of Rd plus 0,2% of FS)
- Pressure ratings up to 700 bar (higher on request)
- Electro-chemical polish of all surfaces
- Rugged, weatherproof housing (IP65, dust and waterproof)
- Available with ATEX approval for Zone 2
- No moving parts
- Analog or digital communication (RS232 or fieldbus interface)

Applications

- Process gas measurement in food industry, chemical and petrochemical industries, in fermentation installations and in biotechnology
- Sample gas measurement in environmental analysis
- Gas consumption measurement for internal accounting
- Systems for environmental air sampling
- Hydrogen techniques
- Burner control
