MASS-STREAM Thermal Mass Flow Meter for GasesMS-105 and MS-109

MASS-STREAM mass flow meters for gases are based on the thermal through-flow measurement principle

Covering a wide measurement range, from 0.5...50 ln/min up to 10...1000 ln/min Air equivalent. 
Each Mass Flow Meter is equipped with exciting features, like our multi-functional on-board display for indicating actual flow, totalized flow, and alarms.

All 4 models, shown in the table below, have 6 pre-installed gases: Air, N2, O2, Ar, CH4, CO2;
analog 4-20mA output signals and Digital RS-232 communication.
With Bronkhorst's FLUIDAT Onboard it is possible to select other gases or mixtures via our free software Bronkhorst FlowSuite.

Which thermal mass flow meter is best for gas?

The thermal Mass Stream Bronkhorst® mass flow meters 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.

  • The MASS-STREAM thermal mass flowmeter series operate on the principle of direct thermal mass flow measurement (no by-pass); rather than measuring the volume flow it measures the actual mass flow, without the need of temperature and pressure correction.MASS-STREAM Thermal Mass Flow display
  • The modern multi-coloured TFT display provides an multi-functional display: actual flow, fluid sets, totalizer with memory and reset, alarm, setup and more.
  • With Bronkhorst’s FLUIDAT Onboard it is possible to select other gases or mixtures via our free software Bronkhorst FlowSuite
  • These models have 6 pre-installed gases on board that can be set via the onboard display; Air, Nitrogen(N2), Oxygen(O2), Argon(Ar), Methane(CH4), Carbon dioxide(CO2)
  • The digital thermal gas mass flow meters are standard equipped with 4…20 mA and RS-232 output signals.
  • The highly accurate FLUIDAT gas database ensures best in class conversion from Air to the customer gas. Additionally, the on-board gas database is used for real-time corrections of the flow measurement based on the actual process temperature.

Which Thermal Mass Flow Meter Is Best for Measuring Nitrogen or Air?

The MASS-STREAM thermal mass flow meter is factory-calibrated using air as the reference gas, which ensures high accuracy and reliability for air flow measurements. Bronkhorst High-Tech utilizes intrinsic fluid data such as molecular mass, critical properties, and boiling points to provide precise conversion factors. This allows the MASS-STREAM flow meter, originally calibrated on air, to be effectively used for nitrogen flow measurement and other gasses with minimal loss of accuracy.Thermal Mass Flow Meter MASS-STREAM

Key features of the inline MASS-STREAM series:

  • Multi-coloured TFT display with operator buttons (IP65 compliant)
  • Ideal for industrial gases (6 pre-installed gases and more with FluidatOnBoard 
  • Very good and competitive accuracy
  • Excellent repeatability
  • Less sensitive to contamination, like dirt, moisture and/or humidity
  • Low pressure drop across sensor
  • Compact and robust design
  • Suitable for sub-atmospheric applications

Whether you need a flow meter for industrial processes, research labs, or quality control, MassFlow-Online offers fast shipping, expert advice, and competitive pricing to ensure you get the best device for your specific nitrogen or air flow measurement needs.
