LOW-ΔP-FLOW Series, Low Pressure Drop Mass Flow Meters and Controllers

LOW-ΔP-FLOW Series, Low Pressure Drop Mass Flow Meters and Controllers

Product Overview

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.

Description

  • Very low pressure drop
  • Longer lifetime when used on corrosive gases
  • Lower contamination risk
  • Easy to clean
  • Electro-polished stainless steel wetted parts
    Available with control valve to constitute a complete, compact control loop
  • Available with industrial (IP65 weatherproof) housing with optional ATEX Zone 2 Cat. 3 or FM Class I, Div. 2 approval.
  • Best in class mean-time-between-failure (MTBF) data based on the IEC 61508 standard

Applications

  • Environmental air sampling at atmospheric conditions
  • Leak rate tests
  • Gas consumption measurement, for example of natural gas, in low pressure gas distribution systems
  • Burner control
  • Diamond deposition HFCVD

“Multibus” Digital Mass Flow Meters and Controllers

LOW-ΔP-FLOW Series low delta pressure mass flow meters and controllers have a flexible “multibus” concept, which allows the instruments to be equipped with on-board interface board with CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocol.
