Laboratory & instrumentation Mass Flow Meters and Controllers for gas applications with an electronic housing suitable for laboratory conditions. EL-FLOW® series instruments are truly unique in their capability to control flow ranges between 0...0.7 mln/min and 0...1670 ln/min with pressure rating ranging between vacuum and 400 bar - all in one range of instruments. This versatility in flow ranges and in operating conditions has ensured that the EL-FLOW® series remains our most popular and field proven of instruments. ♦ Best accuracy: ± 0.5% of reading + ± 0.1% of F.S. ♦ Analog and digital (fieldbus)...

LOW-AP-FLOW series Mass Flow Meters and Controllers are derived from the EL-FLOW series. The special construction of both sensor and flow restriction makes this series suitable for low pressure drop applications (the sensor only requires 0.5 to 5 mbar). Furthermore the larger flow channels minimize the risks of clogging and facilitate the cleaning and purging of these LOW-AP-FLOW instruments. ♦ Very low pressure drop ♦ No moving parts ♦ Suitable for corrosive gases ♦ Also available with IN-FLOW ♦ All stainless steel construction industrial housing ♦ Analog and digital (fieldbus) communication...

Liquid - thermal mass flow Mass Flow Meters and Controllers for liquids in ranges between 0...100 mg/h and 0...1000 g/h (water equivalent). The flow meters only require a small differential pressure. Despite utilizing direct measurement (i.e. without a by-pass) the temperature rise of the fluid is minimal; only approx. 1.5 °C. This greatly limits the danger of evaporation or degradation of the fluid. ♦ Fast and accurate measuring signal ♦ Analog and digital (fieldbus) communication ♦ Thru-flow measurement (no by-pass) ♦ Insensitive to mounting position ♦ Industrial style (IP65) available > Flow...

♦ Accurately controlled gas/liquid mixture (mass flow) ♦ Very stable vapour flow ♦ Handles water, solvents, liquid mixtures The Bronkhorst® electronic pressure meters and controllers have a well-proven compact thru-flow design and are available in pressure ranges for 0... 100 mbar up to 0...400 bar. A differential pressure transmitter can also be supplied in the range ofO.,,15 bar. The pressure controller performs with high accuracy and repeatability and should be specified for forward pressure control or backward pressure control. ♦ Suitable for liquids and gases ♦ Analog and digital (fieldbus)...

Digital 'multibus'instruments The product series mentioned in this brochure can be supplied with analog or digital communication. Bronkhorst developed their latest digital Mass Flow Meters/Controllers according to the "multibus” principle. The basic pc-board on the instrument contains all of the general functions needed for measurement and control, including alarm, totalization and diagnostic functions. It has analog I/O-signals and also an RS232 connection as a standard feature. In addition to this there is the possibility of integrating an interface board with DeviceNet™, PROFIBUS DP, PROFINET,...
