产品介绍
For applications with only little differential pressure, Bronkhorst High-Tech 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 mln\/min.highest range 20 ... 1000 m3n\/h.","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 High-Tech 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 High-Tech developed their digital instruments according to the flexible \"multibus\" concept, due to which the instruments can be equipped with on-board interface board with DeviceNetTM, Profibus-DP®, Modbus or FLOW-BUS protocol.
