LOW-ΔP-FLOW Series, Low Pressure Drop Mass Flow Meters and Controllers
Designed for low pressure drop or corrosive gas service applications with only little differential pressure. The LOW-ΔP-FLOW Series mass flow meters and controllers are able to minimize the flow resistance by a unique sensor and by-pass construction.
- Lowest range 0.2…10 mln/min
- Highest range 20…1000 m3nh
Control of Mass Flow with Small Pressure Differences
The control of mass flow with small pressure difference comprises the LOW-ΔP-FLOW Mass Flow Controller in compact construction; control valve and flow meter are integrated in one body. The maximum flow in these compact models is 1-50 ln/min Air, depending on the operating conditions. For the control of higher flow rates at very low differential pressures, special control valves with pressure compensation bellows may be used (types F-004AC/F-004AI/F-004BI). These control valves are piped on to the flow meter while the electronic PI-control function is an integral part of the flow meter.
