MASS-STREAM™  Thermal Mass Flow Meter for Gases

Direct Through-Flow Measurement

Bronkhorst High-Tech proudly presents the latest innovation in our MASS-STREAM series: the robust D-6400 generation, now available for online purchase exclusively on Mass Flow Online. With our streamlined ordering process, expect prompt dispatch within just 2 business days when items are in stock.

MASS-STREAM mass flow meters (MFM) for gases are based on the thermal through-flow measurement principle. 
Bronkhorst Instruments in Germany is fully focusing on this field-proven design since 1997.  Unlike thermal bypass flow meters, all gas flows through a straight channel, making MASS-STREAM instruments very robust, less sensitive to moisture or particulates, and easier to clean.

Mass Flow Online has selected four models for their online sales channel, covering a wide measurement range, from 0.5 to 50 up to 10 to 1000 ln/min air equivalent. 
Each Mass Flow Meter is equipped with an on-board display for indicating actual flow, totalized flow, and alarms.
