MASS-STREAM™ D-6400 Mass Flow Meters and Controllers for Gases

The thermal Bronkhorst® mass flow meters and controllers for gases based on direct through-flow measurement are produced in Germany since 1997. The MASS-STREAM™ series D-6400 works following the constant temperature anemometer principle. Our MASS-STREAM™ instruments cover a wide range of measurement and control applications in almost every industry sector - like mechanical engineering and process industry, gas production, food and beverage industry as well as environmental engineering and the chemical industry. We are committed to a long lasting cooperation with our customers and of course we...

The digital MASS-STREAM™ mass flow meters (MFM) and controllers (MFC) are operated with a main-board with all functions for the flow measurement and control. The instruments can be supplied with commonly used digital or analog input/output signals and when ordering a digital instrument please forward the required presettings. Along with the standard RS232 interface the additional fieldbuses CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus (RTU, ASCII or TCP/IP), EtherNet/IP, POWERLINK and FLOW-BUS are also available. The digital MASS-STREAM™ model series is characterized by a high...

> Standard measurement ranges Mass flow meter/controller Flow ranges (Air) Model intermediate ranges are available Technical changes and alterations in construction are reserved. > On-board FLUIDAT®gas database The on-board gas database contains the physical gas properties and is used for real-time corrections of the flow measurement based on the actual process temperature. As an optional feature, you may simply select your process gas, and benefit from the multi fluid, multi range possibilities of the D-6400 series. With the on-board gas database, it is very easy to switch to another gas or...
