MASS-STREAM™ Series D-6300 Digital Direct Mass Flow Meters and Controllers for Gases


The new digital MASS-STREAM™ series D-6300 works on the basis of direct through-flow measurement, following the constant temperature anemometer principle, and replaces the analogue series D-5100 / D-6200.

The MASS-STREAM™ series D-6300 is characterised by significant improvements, covers flow ranges from 0.01…0.2 ln/min up to 100…5000 ln/min (Air). 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, PROFIBUS DP, DeviceNet, FLOW-BUS and Modbus-RTU 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, the new 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.
