MASS-STREAM Thermal Mass Flow Meters / Controllers for Gases

Direct Through-Flow Measurement

The digital MASS-STREAM™ series D-6300 & D-6400 work on the basis of direct through-flow measurement, following the constant temperature anemometer principle.

Lowest range 0,01…0,2 l_n/min
Highest range 200…10000 l_n/min

Video MASS-STREAM Thermal Mass Flow

Video animation explaining the functions and features of Bronkhorst's MASS-STREAM Mass Flow Meters and Controllers for gases, following the direct through flow measuring technique.

IP65 design with optional multi-functional and multi-colour display

The instruments have IP65 protection as a standard and are operated with a main-board with all functions for accurate flow measurement and control. They can be supplied with commonly used digital or analogue input/output signals. Along with the standard RS232, CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS are available as an option.

One key element and innovative improvement is the optionally integrated, modern, multi-functional and multi-colour display, fully IP65 compliant with operator buttons on the instrument. With its multiple functions, such as actual flow indication, totalisation and alarms, MASS-STREAM™ series D-6300 offers an excellent price-performance ratio. The instruments are suitable for application in laboratories, production machinery as well as industrial installations.
