High precision mass flow meters and controllers for gases, Type 8741 and 8745 offer a choice of industrial Ethernet protocols, including Profinet, EtherNet/IP, EtherCAT or Modbus TCP. Typical applications include metal, glass or ceramic processing, coating technology or in the production of foams in the food and plastics industries. Type 8741 handle nominal flow rates of up to 150 lN/min (relative to N2) while the Type 8745 devices permit a maximum of 2,500 lN/min (relative to N2). The mass flow controllers employ direct-acting proportional valves. The sensors measure directly in the gas flow, and the thermal measuring principle operates independent of pressure and temperature fluctuations.
