LOW-ΔP-FLOW
Mass Flow Meters/Controllers for low pressure drop or corrosive gas service

General

For applications with only little differential pressure, Bronkhorst® developed the LOW-ΔP-FLOW series mass flow meters and controllers. In these instruments, the flow resistance is minimized by a different sensor and by-pass construction.

lowest range 0,2 ... 10 sccm
highest range 660 ... 33,000 SCFH

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 Bronkhorst® has devised special control valves with pressure compensation bellows (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.

"Multibus" Digital Mass Flow Meters/Controllers

Bronkhorst® developed their digital instruments according to the flexible "multibus" concept, due to which the instruments can be equipped with on-board interface board with DeviceNet™, PROFIBUS DP, Modbus, EtherCAT® or FLOW-BUS protocol. More information about digital "multibus" communication.
