What Is a Mass Flow Meter—and How Does It Work?

A mass flow meter is an instrument that measures the mass of a gas flowing through a pipeline per unit of time. This may sound simple, but the distinction from traditional volumetric flow meters is crucial. Volume is heavily influenced by environmental factors like temperature and pressure.
One cubic meter of gas at 1 bar and 20°C contains far fewer molecules (mass) than the same cubic meter at 10 bar. For chemical reactions, combustion processes, or accurate dosing, the number of molecules—the mass—is the determining factor, not the volume. 
(More info What is the difference between mass flow meters and volume flow meters?)

Unlike volumetric flow meters that must compensate for fluctuations using additional sensors and calculations, a mass flowmeter measures molecular mass directly. This makes them essential for processes where precision and repeatability are critical.
The instruments we offer primarily operate on the thermal measurement principle: a small portion of the gas stream is heated or a temperature difference is created. The degree to which the temperature changes (under constant heating) or the energy required to maintain a constant temperature difference is directly proportional to the mass flow rate and the heat capacity (Cp) of the gas.

With advanced sensor technology, this results in highly accurate, fast, and stable measurements—crucial for quality control in your process.

Why Choose a Bronkhorst Flow Meter?

If you work in industry, the name Bronkhorst is likely familiar. A Bronkhorst flow meter is globally synonymous with high‑quality Dutch engineering, robustness, and continuous innovation.
Bronkhorst High‑Tech B.V. has been the market leader in thermal mass flow meters and controllers for low‑flow applications for decades.

Massflow‑online is the official e‑commerce channel for Bronkhorst. This is an important distinction: you are not buying grey‑market imports or leftover stock, but brand‑new, factory‑original instruments that meet the strictest quality standards.

Customers choose a Bronkhorst mass flow meter from our MASS‑VIEW, MASS‑STREAM, or FLEXI‑FLOW series for the following reasons:

• Unmatched Reliability: Designed for long‑term, trouble‑free operation—even in industrial environments with vibration or fluctuating temperatures. MTBF values are exceptionally high.
• Versatility and Flexibility: Many instruments are multi‑fluid or suitable for several common gases (such as Air, N₂, O₂, CO₂, Ar, CH₄). One meter can cover multiple applications, simplifying inventory management.
• Innovation & Digitalization: Examples include the MASS‑VIEW series, the digital smart alternative to traditional VA meters (rotameters), or the new FLEXI‑FLOW series, which combines ultra‑fast response times with compactness.

The Evolution: From Rotameter to MASS‑VIEW

 Traditional rotameters (Variable Area meters) are still often found in laboratories and factories. While inexpensive, these analogue tubes with a floating ball come with disadvantages: parallax reading errors, fragile glass, and immediate accuracy loss when pressure or temperature fluctuates.For users seeking precision, they are no longer suitable.

This is where the mass flowmeter from our MASS‑VIEW series comes in. Designed to mimic the look and feel of a rotameter but with the performance of a modern mass flow meter.
You get a bright OLED display with a digital bar graph for instant readability. More importantly, the device offers electrical output signals (analogue or digital/Modbus), enabling data logging, alarms, and process automation.

Ordering an Online Mass Flow Meter: The Benefits

Traditional instrument procurement is often slow. For highly engineered custom systems, that makes sense. But for standard applications, it’s inefficient and costly. Looking for an online mass flow meter that can be delivered tomorrow? Our streamlined approach is the solution.

Benefits of Massflow‑online:

• Transparent pricing: No hidden costs or “price on request.”
• 24/7 ordering convenience: Buy when it suits you—no sales engineer required.
• Fast delivery from stock: Most orders ship within two business days.
• Complete documentation: Datasheets, manuals, and drawings available instantly.

Choosing the Right Mass Flow Meter: A Quick Guide

Selecting the correct meter is simpler than many think. Answer these core questions:

1. What Gas are you measuring?

Our instrument MASS-VIEW works on 100% pure gas. It's not possible to measure a mixture of certain gases.
If you know the gas mixture you can use the MASS-STREAM or FLEXI-FLOW to setup the mix of the gas in the instrument with Bronkhorst FlowSuite and measure. 
Always check material compatibility and its a clean gas. 

2. What is the required flow range?

Small laboratory flows (0-5 ml/min)? Or large industrial flows (hundreds or thousands of ln/min)?
• MASS‑VIEW: 10 mln/min → 500 ln/min
• MASS‑STREAM: up to 1000 ln/min
• FLEXI-FLOW: 5 mln/min → 500 ln/min

3. What are the process conditions (Pressure & Temperature)?

The MASS-VIEW and MASS-STREAM can measure up to 10 bar (g).
The FLEXI-FLOW up to 16 bar (g).
Temperature range is 0 … 50 °C

4. Do you need local display?

MASS‑VIEW and the MASS‑STREAM models include displays. 
The FLEXI-FLOW doesn't have a display, but can be readout with phone with Bluetooth connection.

5. What output signal is required?

Analogue (4–20 mA, 0–5 V) or digital (Modbus, FlowBus)
We have differente output, check the models which suits your needs

Massflow‑online vs. Other Providers

You may encounter brands like Krohne, Brooks, Alicat, or MKS. These are reputable alternatives, but differ in pricing, delivery time, and purchasing process.

At many vendors—including traditional Bronkhorst channels—you need a full quotation process.
At Massflow‑online, a Bronkhorst flow meter becomes an “off‑the‑shelf” product: same quality, faster and often cheaper.

Real‑World Applications: Where Are Our Meters Used?

Our mass flowmeter products are used across industries:

 1. Gas consumption measurement in hospitals and labs
